When a fisher casts his line into the water, the location where he sees the fish is not actually where the fish is, due to refraction light. given that the index of refraction is higher in water than in air, is the fish actually farther from the fisher or closer compared to where he sees it?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
