In 6 seconds, a total of 3 waves crash onto the shore of a beach. The distance between each wave crest on the water is 8 meters. Find the: Wavelength
Period
Frequency
Wave Speed v=d/t.

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
