The position of a particle going along a straight line is x1 = 50 m at 10.30a.m. and x2 = 55 m at 10.35 a.m.The displacement between 10.30 a.m and 10.35 a.m. is :
2 m
5 m
7 m
9 m

A particle is travelling with a constant speed. This means that
its position remains constant as time passes
it covers equal distances in equal time intervals
its acceleration is zero
it does not change its direction of motion
Velocity is a
scalar quantity
vector quantity
Both scalar and vector
none of these
The sound produced by musical instruments in big halls may linger even after the instrument stops producing sound. This is known as
