This would explain why when they are playing at the same time, there was an odd but clear sound that they were not supposed to produce.
    
    The reason for this is because whenever any objects vibrate or moves, it produces interference. When one object moves in a particular direction or changes its motion suddenly, there will be waves forming in all directions. If another object has these waves hitting them as well while moving around by itself then there will be interference which will result in having waves being lost or changed.
    
    The concept of physics used is applied in the principle of interference. When two or more objects cause vibration or motion, there will be waves colliding with each other and either being canceled out or changed by a small fraction. This is an example of interference that can lead to many different problems down the road.  less

Here when they both play the guitar simultaneously both of them produce waves of similar Frequency. These waves are produced interact with eachother & produce constructive & destructive superposition. This leads to amplitude at a few points to become double as displacement at that point is high. This leads to the loud noise as high amplitude is responsible for high sound. To avoid this they need to play different cords or change the frequency of the waves produced.  less

    the acoustic guitar synchronously,two sound waves were generated from two guiters at the exact same time.I mean each one produced the same sound wave and both the waves were in same phase.Now,what is phase!
    
    
    If two waves have the same amplitude,same frequency and same wavelength,then it is said that both the waves are in same phase.
    
    
    So when two or more same-phased
    waves arrive at the same point (when both started playing their guitar),the waves superimpose themselves on one another.Actually the amplitudes of the wave superimpose.This term is known as-Superposition.So,the resultant wave will simply be the addition of the amplitudes of the individual waves.This superposition
    produces Constructive Interference which produces a wave that has twice the amplitude of the individual waves.The higher the amplitude,the louder the sound
    will be.
    
    
    On the other hand,it can be said very easily...    less

    each other,the resulting amplitude is zero which is known as-Destructive Interference.It means the two waves cancel each other.Therefore,no sound will be produced.
    
    From this discussion,it has been realized that when Sarah & Ali started playing at the same time,the sound waves generated from their instrument superimposed on each other and created the wave which had twice the amplitude of that individual wave.So a loud thumping noise was
    generated.But their ear were get used to it slowly.So,it didn’t affect that much later  less

    Hasnain Tariq actually this happens due to resonance frequency . this is the frequency where superposition of waves can generate. same happen in the case of Sarah and Ali frequency of both musical instrument match suddenly this create loud thumping noise.

Moment of force is the idea to make a body to rotate on a pivot. Moment has a simple rule that is the closer you are to the pivot or the point the more energy you would require to rotate the body. This rule is obeyed by many objects which we use in our day-to-day life. Like a spanner handle is placed far from the pivot to rotate the nut or nail easier with less force. Similarly, in this case the pivot is the root of the tree, it is the turning point for the tree, when the crowd gathered they applied force very close to the pivot or the root this cause the tree not to budge but when Andy positioned the force on the far end from the pivot it made it easier for the crowd to move the tree. In simple, we can sum it up that the greater the distance the less the force needed and the smaller the distance the more force is needed which this scenario perfectly portrayed.  less

Momentum is the product of force and the perpendicular distance between the pivot and line of force. He considered providing a force greater than the weight of the tree, but this is only feasible if the force is delivered on the other side of the root.
    It is a fact that when a force is applied far from the pivot, the force is sufficient to elevate the other force/weight. Mr. Andy used that notion when assisting the individual.

The idea about moments is that the further a force acts away from the pivot(the turning point of an object), the more effective it will be in turning the object. For example, the knob of a door is situated the farthest from its pivot, the hinges. In the picture, we can see that the tree is tilted down towards the side of its roots. From this, we can guess that(counting the car as a pivot) there is a greater load acting downwards in that side of the tree, than the side with the leaves. The way the people were doing it before, they were wasting strength overcoming all the those forces and uprooting the tree. They were using the car as a pivot, and the distance between their force and the car/pivot was not much. However, pushing in an anticlockwise direction on the other side, with the leaves, shifts the pivot from being the car to being the roots, all the way on the other side of the tree. The pivot being far away, the forces proved effective.  less

As mentioned in the scenario, the roots of the tree were fixed with the ground so it was a fixed point and a fixed point is called a pivot. This pivot allowed the tree to be removed over the car. According to the principles of moment, the distance from the pivot to the point where the force is applied is directly proportional to the moment, meaning the longer this distance, the greater the rotation of the tree and that is why Mr Andy applied his force on the farther end of the tree so that with less force would produce greater moment due to the longer distance, away from the tree and was successful to remove it and save the passenger.  less

    The car was acting as a pivot here because the weight of the whole tree was on the car. The bottom side of the tree was not uprooted, so it was heavier than the upper part, so more force was needed to lift it from near the roots. Therefore, it was easier to lift the tree upwards at a certain distance away from the root of the tree as there was less weight in the upper direction.
    Today, we learned about a great example in the field of physics. this topic can be identified as the 'moments'. Moments are directly proportional to the force and distance of a body, just like this one! Easy-Peasy!  less

According to a research by The Asia Foundation its seen that from 1999/2000 to 2016/2017 the number of female workforce has increased from 8.6 million to 19.9 million which is more than twice & this is largely due to the increased literacy rate of women which stands at 71.95% & safety of women in job sector. The rise in women workforce is also due to Introduction of programmes like Microfinance from NGO’s like BRAC & others. Bangladesh also is the 2nd largest exporter of RMG & the workforce in this sector is largely made up of women. All these has lead to the rise of women involvement in job sector & this has lead to huge economic growth of the country.
