Question

a quantity is a value of 10m/s . it may be the​

Answer 1

Answer:

Explanation:

Required Answer:-

The given quantity is -10 m/s.

The unit is metre/sec which means length is divided by time which results in this quantity. This can be either velocity or speed. Now, we can see them both in the options.

   Velocity is a vector quantity which is expressed by both direction and magnitude. It can positive, negative or zero.

   Speed is a scalar quantity which is expressed by magnitude only. It can be positive only for a moving body

Hence:-

The quantity represented by the value -10 m/s is the velocity of particle i.e. Option B.

Rest options:-

   Displacement has a unit of m. (A/q)

   Position can't be negative (distance travelled is the actual length covered).

   Speed can't be negative.
