A centrifuge used in DNA extraction spins at a regular rate of 7000 rpm. Producing a "g force" on the sample that is 6000 times the force of gravity. If the centrifuge takes 10s to come to rest from the maximum spin rate a)what is the angular acceleration of the centrifuge b) what is the angular displacement of the centrifuge during this time?

What are the factors that affect the resistance of a wire?
