Consider two blocks of copper. block a contains 800 atoms and initially has a total of 20 quanta of energy. block b contains 200 atoms and initially has 80 quanta of energy. the two blocks are placed in contact with each other, inside an insulated container (so no thermal energy can be exchanged with the surroundings). after waiting for a long time (for example, an hour), which of the following would you expect to be true?
a. the temperature of block a and the temperature of block b are equal
b. approximately 50 quanta of energy are in block a, and approximately 50 quanta of energy are in block b.
c. the entropy of block a is equal to the entropy of block b.
d. approximately 80 quanta of energy are in block a, and approximately 20 quanta of energy are in block b

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
