A 300 gg ball on a 70-cmcm-long string is swung in a vertical circle about a point 200 cmcm above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height 600 cmcm above the floor. Part APart complete What was the tension in the string an instant before it broke? Express your answer to two significant figures and include the appropriate units. TT = 34 NN

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?

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

How does changing the frequency affect the energy of the wave?
