An object may have:
  • A
    Varying speed without having varying velocity.
  • B
    Varying velocity without having varying speed.
  • C
    Nonzero acceleration without having varying velocity.
  • D
    Nonzero acceleration without having varying speed.

Answer

  1. Varying velocity without having varying speed.
  1. Nonzero acceleration without having varying speed.

Explanation:

Velocity and acceleration are vector quantities that can be changed by changing direction only (keeping magnitude constant).
