Physics Questions

A body is initially moving with a velocity of 5 m/s. It undergoes an acceleration of 2 m/s2 for 4 seconds. Find the displacement (in m) of this body in these 4seconds.

The reflection formed by the plane mirror is ________________.

_______________ states that the ratio of the potential difference across a conductor to the current flowing through it, is a constant, provided that its physical conditions, such as temperature, remain constant.

Due to an acceleration of 4 m/s2 the velocity of a body increases from 10 m/s to 30 m/s in a certain period. Find the displacement (in m) of the body in that period.
