In the light of physics, pressure is the amount of force applied per unit area. That is P=F/A. Now in case of cutting something using a knife, you have to put pressure on the thing you want to cut. It is mentionable that,less the area is, more the pressure will be. That means pressure is inversely proportional to area. You know that, a sharp knife have less area on the cutting edge than the blunt one. As a result, by giving equal force the pressure by the sharp knife will be more than the blunt one. To do the same work, you have to give more pressure on the blunt knife for which the possibility of slipping the blunt knife with greater force will be more. And that would be dangerous for you as this can cause serious damage. For this reason, it is recommended to use sharp knives rather than blunt knives to cut vegetables.  less

    If you’re using a knife to peel a potato or carrot, the dull knife can stop on an irregular surface, forcing you to use excessive pressure to get past it. If the knife blade suddenly slips, you’re likely to cut yourself as it suddenly speeds up.
    Dull blades make cutting meats harder and make you use extra force to cut through any tougher part of the meat. Once it cuts through and can move easily, quite often you’ll cut your other hand when the blade moves quickly due to the force you’re using.
    A sharp blade cuts easily through most foods and only light to moderate pressure is required. It’s easier to guide and control a sharp blade due to its consistent cutting ability.  less

    A blunt knife, on the other hand, is quite likely to slip off the surface of some harder or tougher objects - and this means it will go in a direction you did not intend - perhaps in the direction of your fingers. To compensate for the loss of cutting action, you'll find yourself applying more force - which means you may no longer be in control of the blade; you might not even be holding it properly any more - and then, when the blade still slips and goes where it isn't meant to, it will arrive with far greater force, possibly cutting you quite badly.
    A blunt knife also tends to crush the food, rather than cutting it - so with something like an onion, the layers will...    less

But a blunt knife will create laceration which will create irregular edges in the wound creating a risk of infection. According to physics, we know that a unit of force (1 newton) applied to a unit area (1 meter squared) perpendicularly will create 1-pascal pressure. The formula being P=F/A (n/m^2). So, the more we apply pressure to the handle of the knife, the more the pressure is in a smaller surface area. This makes the point of contact of the vegetables precise and allows swift and clean cutting. Whereas the blunt knife having a larger surface area, won't have the same penetrating force which will result in a twisting force called torque. So the knife will rotate and cause injuries to the hand.  less

Sharp must have a thin edge and the Blunt has a thick edge. So the edge area of blunt is bigger than sharp. When you put the same force on both of them, the force is distributed in the smaller portion of Sharp's edge area and makes more pressure directly on surfaces and makes a quick cut. The same force will be distributed in the bigger portion of the Blunt's edge area and as the force spreads in a bigger place, the pressure becomes weaker on the surface and makes it harder to cut thoroughly. Sharp knife bite the surface with its thin edge and the blunt knife can't sit properly, so it becomes slippery and risky.
    In physics term, force/area=pressure. Here, forces are equal. Sharp knife has a smaller and blunt knife has a bigger area. When you divide the same number with a small and a large number, they result in a big and a small number(pressure) respectively. So the pressure of a sharp knife will be greater than blunt one.  less

But if he had used the sharp knife where the edge so sharp and it can go through anything. The area of a sharp knife is so small, and from that equation, you have guessed that the pressure will be high. So it will be so easy to cut vegetables into dices or any shape he wanted, That's why chefs sharpen their knife before use. But during the cut, he needs to careful that it doesn't hurt him.  less

    Sourav Chowhan With a sharp knife, he doesn't have to give much pressure on cutting, so that's why it will be safer.
    That's why it is safe to use a sharp knife than a dull knife. It will save you both time and energy.

    P=F/A
    where, P= applied pressure on the object
    F= force applied on the object
    A= the area of the object where pressure is applied
    Let's consider in above circumstances, adam applied the same amount of force on the carrot he was cutting with both the sharp and blunt knife. His ease of cutting will be dependent on whether the area of applied force is lesser than the other or not. Now, with common sense, we can easily understand that the sharp one has a lesser area of pressure than the blunt one because the edge is much narrower. So, more pressure will be put on using the sharper one.
    The risk of using a blunt knife is that it may slip the vegetable adam is cutting and may severely injure his hand. We don't want any harm to be done to this nice fellow. That's why his instructor advised him to use a shape knife in order to cut them with ease and safety while taking less time.  less

    Adam tried to cut the carrots using a blunt knife. He couldn't do that in brunoise cut and he almost cut his hand. His teacher mentioned that the sharp knife is efficient to cut any food. If you try to cut a cucumber using a blunt knife it would require you to exert more strength/force. The knife may slip if the sharp end is too thick. Whereas if you use a sharp knife you can efficiently do that by exerting less strength/force
    
    This is because of the force and the surface area. The surface area of the sharp end of a blunt knife is more than that of a sharp knife. We get from pascals law that Pressure is inversely proportional to the surface area. So if you apply the same amount of force for both the knife, the sharp knife would be more efficient. So sharper knife is safer in cutting food...    less

So he has to apply force in the knife which makes the pressure cut the Carrots. Here another physics term arises that is cutting Area of the knife. With all of these things, we can get a relation from physics that is Force=Pressure/Area
    Here we can see that Force is inversely proportional to Area . This means that if Area is increasing then Force will decreasing & similarly if the Area is decreasing then the Force will increasing with the proportion to each other.
    To cut the Carrots properly Adam had to give more pressure when he used the dull knife. Because the dull knife’s cutting area is more than the sharp knife. Moreover while giving more pressure for dull knife it might be slipped and cut his hand. As cutting Area of the sharp knife is less. So he had to give less pressure & did his work nicely and more safely.  less

    The elementary mathematical expression for pressure is giving by ,
    P = F/A
    Here, P is the pressure , F is the force acting perpendicular to the surface to which this force is applied and A is the area of the surface .
    The same force applied by a sharp knife with a smaller area of contact will exerts a much greater pressure than a blunt knife having a considerable larger area of contact .
    Once a blunt knife is through the object (vegetable or other food), there is a greater chance for the pressure to lead to slippage, skidding and injury. A sharp knife can cut using the edge of the e knife with a safer slicing. Rather, cuts from sharper knives can actually heal more easily than those from dull knives. A sharp knife is a safer knife than a dull knife.  less

According to the equation, force is directly proportional to pressure. A blunt knife has more area around the cutting edge than a sharp knife. So a blunt knife requires more pressure for the same amount of force to be exerted, as the pressure applied increases the chances of the knife slipping and cutting Adam's hand increases. Similarly, a sharp knife would require less pressure to be applied for the same amount of force to be exerted, this not only allows Adam to cut through the food but also prevents the knife from slipping and cutting his hand.  less

    So what can he do? In fact, what can guys like Rafiq do??
    Well, there are two things to keep in mind-
    A. Short-Term Immediate Solution
    B. Large-Scale initiatives
    These days almost every nation has good mobile internet coverage. Rafiq can use that to his advantage as internet service providers don't usually cover rural areas. Basically, he can buy a 4G router, a LAN cable, and insert a sim in the router. Buying a
    4G modem from Grammen Phone is another good option to consider. Implementing these methods will give him a better internet connection. So this is the immediate solution.
    However, a poverty-stricken guy like Rafiq will have to spend a decent amount of money every month to maintain the whole. This is where his teachers or classmates must step in. They can raise a fund and make sure that he has everything he needs. This is the classic ALL FOR ONE ONE FOR ALL METHOD. It has to be implemented all over the country on a large scale.  less

    Actually you can get internet access on Android without data plan or WiFi. Fast, simple and unlimited.
    
    Most of USB OTG-capable devices would have no problems with USB Ethernet adapters, at least RINDS-compatible ones.
    
    It's fast - you could easily saturate USB 2.0 with Gigabit Ethernet
    adapter, that's up to 480Mbps. It’s simple - if the network you're
    plugging into has DHCP (most do), it's just plug-and-play. It's
    unlimited - usually there's no traffic accounting on copper ports, at
    least on small networks. And a lot of Ethernet ports available has an
    internet access, be sure to choose one with greater speed.
    
    So, all you need is an USB Ethernet adapter, internet-connected Ethernet
    port at a router (it may look as wall socket with RJ-45 receptacle) and
    a patch cable long enough to get yourself comfortably seated. Enjoy!  less

    classes. Students need an internet connection that’s not only fast enough to handle any assignment or software program their courses require but also cheap
    enough to fit into their budget. So mobile operators in our country should offer affordable STUDENT INTERNET PACKAGES....    less

In the village, there is lots of obstacle to the mobile networks, such as trees, multitude house and so on. But in terms of a certain height, he will you can get enough network speed.
    1. He can make a Ladder to get the height to reach network level, many freelancers works in this method.
    2. Make a network booster like a dish antenna network booster by the semiconductor material. or Simply buy it from daraz.
    3. Use a Pocket router or mobile device at a certain height and in an open space, then open the hotspot and get internet access via wifi system.
    4. Best way He can borrow the internet via coaxial cable dishline from local ISP if there a dish cable network.  less

    As Rafiq got no money, he can lend some money from his students. He can use that money to buy a broadband connection. Thus he can continue his classes and his tuitions as well.
    
    He can also gather more people like him who are facing the same problem and together they can buy a broadband connection and router. Which will result in solving everyone's problem.
    
    He can also get a student loan from his Univesity.  less

    -A Pocket Router and a good quality USB extension cable can solve his problem. To get network inside his home, he can place the router on the bamboo-head or as high as possible, using a USB extension cable of 10 meters or as required. The router must be covered with waterproof something like polythene.
    -GP Pocket Router supports all SIMs. The SIM which provides best network in his village, he can purchase that SIM's data package from the retailer at least at one-third lower price.
    -For the first month, the full cost including the data package, can be up to a maximum of 3500 takas. If Rafiq does not have this amount, he can request to get the tuition fees in advance as the student is known to him. Otherwise, he can borrow the money for a month from somewhere reliable.  less

    1.Getting broadband connection, & connecting it to a router that will cost 2-3 thousand tk for setup and 5-800 tk monthly.
    2. If it's not possible then, second option is buying a router (which can be connected to a modem), a modem and a sim. Thus he can connect the sim to the router through modem. This will cost 2-4000 for set up and 500-1000৳ monthly. This need to be placed in a tall tree or on top of a bamboo stick where the network is good. As connecting electricity at that high place will be tough, he can attach a battery based power system which will backup for minimum 3-4 hours.
    Obviously, he can share his connection to other people who need it and thus reducing the cost to bear by himself.  less

Though this device is a bit expensive (10,000 TK), it has no additional cost for set up. It is free of all the hassle of set up.

Also, each university is now offering it's students 'student loan' in this pandemic, so he can take a loan and go for it easily.

    Rafiq is a University student who earns for himself. Because of Covid's situation, he has to move to his native village. The issues start from here. All income source has stopped.
    
    The situation is, Rafiq does not have a proper internet connection and as a result, he is not able to continue his tuition along with his own classes. Because of his poor financial condition, he must need tuition. An adequate network at the home is the major issue in this case. As he is in the village, the electricity cut-off possibility is high. So, we cannot suggest him for broadband or wifi connection. So, the solution could be a POCKET ROUTER.  less

    Firstly, I will tell them the famous quote of Napolean Bonaparte, "Give me an educated mother, I shall promise you the birth of a civilized, educated nation". By saying this quote I will try to make them understand the how an educated woman contribute to the development of a nation. If a woman is not given proper education, she will not be able to run her family successfully. I will give them a example like, if a woman take her sick child to a pir, fakir or any other superstitious person instead of taking her to doctor and if the child died by maltreatment , it would not the fault of that mother. The family and the society who didn't provide her proper education are the responsible for the child's death.

How a successful girl could change her and her family's social, economic, and all over status by his education. There are many examples of the excellence of girls in our society. The point I will definitely highlight to convince her family and villagers to promote education among girls is that self-independence socially, economically as well as educationally. If we can just highlight some successful girls' biography from our surroundings society to them half of the work will be done by encouraging and make awareness among them. Lastly, try to give her some opportunity to practice and make perfect on the field of the mechanics of technical production on theater, working with presenting, lighting, sound, and vocal effects, and so on technical issues...    less

    At first,education will bring a job for her surely, though job isnt the ultimate goal of education. But I have to convince her family & the villagers to detect their lackings.
    In every religion, education is the basic needs,I will highlight it with the help of Quran,Gita,Bible etc.
    The another barrier is society.In this pandemic, I can show them a great example,if anyone of her family is covid positive,99% people of society won't come to help them.So,society is just illusion.
    Yes,technology can remove the prejudices a little bit.Now there are so many e-commerce, an woman can sell her own nakshi katha,vegetables etc in online.But if she wanna take this opportunity she should have minimum educational background.By earning,she can be empowered also.If she can contribute in her family...    less

And with her permision I will show it to the world. When a person is really talented and the rest of the world know this then no one can stop that person to shine. By the help of technology their parents will know it. And when social pressure will come to them in a good way then the family will feel proud too. This is what things works according to history and I'll do the same.

    a playwright is given below:
    
    
    
    • I will inform
    her about the rights of being independent and making her own choice and decision.
    
    
    • I must educate
    the mentioned girl, her family members, and the villagers about women empowerment
    thoroughly.
    
    
    • I will work
    on diminishing the prejudices that prevail in the rural areas.
    
    
    • I will try
    to eliminate misogyny and male dominance.
    
    
    • I will let
    them know about the benefits of becoming a playwright, about how a playwright can
    get exposure, popularity, financial independence, financial stability etc.

    as a PDF file on Google like Munzereen
    Shahid who has uploaded her spoken
    English Book as a PDF file on Google.
    
    
    I will approach her family with
    the definition of happiness and the meaning of life. I will make a clear concept
    about the possibility of creative work and, How economically profitable it is. An
    educated girl can make herself like Mahfuja
    Minna who lives in Bera, Pabna. And she is a successful dairy farm entrepreneur.  less

    The first thing is to make the parents realize that girls are
    also gifted and talented. She may not be good at other things like cooking, but she has some talent in music or dance which can help her become a playwright later on.
    
    Secondly, we need to convince them by showing how they will benefit if their daughter becomes educated. She can earn for her family in the future and give them better living conditions.
    
    Thirdly, we need to educate them about the virtues of girls
    education by telling stories of famous female writers or other women who have achieved success through learning; this could be a good way to start
    conversations with parents on how they could better support their daughter's interest with small efforts like reading books at home together, etc.
    
    The last thing is to work towards changing the social norms such that girls are given opportunities so they do not feel inferior.  less

University is that platform; it’ll give her proper appreciation & opportunities for raising her talent.
    I’ll approach her instead of her family & introduce her to university & its opportunities. She has to convince her family with her educational performance. No family can marry off her daughter who has a chance to get a great job. Our society emphasizes job than talent. I'll let them do so. A girl with the wonderful educational result can easily persuade his family & society to take part in the university admission test. If she can get herself admitted, the university will do the rest of making her a playwright. Technology can play a big role....    less

To rescue young girls and girls with promising futures out of this curse the society needs to be educated and need to know the value of an educated woman. Firstly, the parents and society need to acknowledge the talent and potential of the girl. If she is promising in activities like dancing or singing then she can build a career around that and help her village and people to improve their lifestyle. Secondly, it's essential to know the side effects of early marriage. The health and mental risk, abuse of the in-laws, and many more. Technology can play a vital role to educate society and giving training and guidelines to reach the girl's goal. Like showing what women around the world have done and link the girl with professionals for proper guidelines.
    This is how I will approach her, her family, and villagers to stop her marriage and give the opportunity to pursue her future.  less
