Has the entropy of the aluminum bar decreased or increased?
A. Since the entropy change of a system is always positive, we can deduce that the entropy of the aluminum bar has increased.
B. Since the final lower temperature of the bar means lower average speed of molecular motion, we can deduce that the entropy of the bar has decreased.
C. We don't have enough information to determine whether the entropy of the aluminum bar has decreased or increased.

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
