A10 g sample of aluminum and a 10 g sample of iron were each heated by 100 joules of energy. the temperature of the aluminum sample rose 11˚c, while the temperature of the iron sample increased 23˚c.

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
