________________ refers to the superposing of two or more coherent waves to produce regions of maxima and minima in space, according to the principle of superposition.
Due to an acceleration of 1 , the velocity of a body increases from 5 m/s to 10 m/s in a certain period. Find the displacement (in m) of the body in that period.
A body is initially moving with a velocity of 10 m/s. It undergoes an acceleration of 2 m/s2 for 5 seconds. Find the displacement (in m) of this body in these 5 seconds.
