Answer 2

hii..

The ratio of mean absolute error to the mean value of a quantity is known Fractional error.

Force acting on a body is directly proportional to the rate of change of Momentum.

Area under a velocity time graph gives Total Displacement.

When no external torque act on a system of particles then Momentum of the system remains constant.
