Answer:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Explanation:
Answer:
The SI units of A, B and C are :
Explanation:
The position x, in meters, of an object is given by the equation:

Where
t is time in seconds
We know that the unit of x is meters, such that the units of A, Bt and
must be meters. So,


So, the SI units of A, B and C are :

So, the correct option is (B).
