alleryInstantaneous speed is the magnitude of:
AVacancy
BVelocity
CVicinity
DViscosity
Answer & Solution
Correct answer: B. Velocity
1. Speed and velocity differ in one respect only.
2. Dropping the direction of velocity leaves its size.
3. Instantaneous speed or simply speed is the magnitude of velocity.
4. So the answer is velocity.
