Which scenario describes a change in velocity? A. A skydiver that has reached terminal velocity (a constant speed) while falling.

B. A ride that spins clockwise and then counterclockwise.

C. A car traveling east at 55 km/hr.

D. A plane traveling at 800 mph at cruising altitude.

B

Explanation:

Velocity is the distance covered in a specific direction per time taken. It is a vector quantity.

When an object reaches terminal velocity, the velocity will be constant.

But a ride that spins clockwise and then counterclockwise. Will experience many changes in velocity. Since velocity is a vector quantity which has both magnitude and direction.

Change in direction is tantamount to change in velocity. Therefore, the scenario that describes a change in velocity is a  ride that spins clockwise and then counterclockwise

c)as speed changes, wavelength and frequency change.

everything changes!

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
