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 membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 Ă— 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
