Explanation / Answer

29) d) Displacement is a vector , Distance is a scalar

Distance : the length of a path travelled by an object.

so, distance does not have a particular direction. so, it is not a vector. it is only a scalar.

Dispalcement: The shortest distance between initial point and final piint is called displacement.

So, displacement has a particular direction. so, it is a vector.

speed = distance/time taken so, speed is a scalar

velocity = displacement/timetaken so, velocity is a vector.
