Constructive interference means that the waves combine instead of negate. if they are both amplitude x, adding them together would result in 2x, or doubling the amplitude of one of the waves
As it is given to us
also it is given that
P - Q + R = 0
so here we can rearrange it to find the value of R
so here we have
so the vector is given by above equation
According to Newtons 3rd law of Motion, for every action, there is an equal and opposite reaction. So if the boy is pushing forward on a crate with a force of 100 newtons, the crate is pushing back on the boy with a force of 100 newtons. Hope this helps
