(1)Before the rod is brought near, the stream of water is uncharged. (2) When the positively charged rod is brought near the lower part of the stream, it attracts the negative (-) charges in the water and they shift a little closer to the rod. The plus ( ) charges stay where they are. (3) With the negative charges in the water closer to the rod, the attractive force between them and the positively charged rod is stronger than the repulsive force between the positive charges in the water and the rod. Thus, there is a net attractive force and the lower part of the water stream is attracted to the rod, and so the stream bends. How would you evaluate the written part of his explanation

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
