The answer is the option a. <span>a. a ball moving at a constant speed around a circular track.
Acceleration is the change in velocity. This change may be either on speed or on direction (or both).
A ball moving at a constant speed around a circular track is continously changing its direction so it is under acceleration (centripetal acceleration).
All the other cases are of objects moving at the constant speed and in straight line, i.e. constant velocity, which is not accelerating.

Boyle's law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 4l , the pressure is 720 kpa (kilopascals). What is the pressure when the volume is 10l ?
Answer:
3.78 m on the left side of the seesaw
Explanation:
The net torque in this situation is zero, so the torque from each side of the pivot point must balance each other out:
(50.0 kg x 10.0 m/s^2)(3.4m) = (450 N) r
Solve for r, and you get 3.78 on the left side.
Hope this helps!
