Agirl and a boy are riding on a merry-go-round that is turning at a constant rate. the girl is near the outer edge, and the boy is closer to the center. who has greater angular displacement?

Both have equal angular displacement.

Explanation:

Angular displacement in rotational motion is analogous to displacement in linear motion. It is the measure of angle in radians moved by a point about an axis.

In the given question, both girl and boy are riding same merry-go-round which is turning at a constant rate. Both would move the same angular displacement in a given time. This is because angular displacement does not depends on the distance from the axis of rotation.

it has to be b, about 97 percent.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
