Object a attracts objects with a gravitational force of 5 newtons from a given distance. if the distance between the two objects is reduced in
half, what will be the changed force of attraction between them?
a 2.5 newtons
b. 10 newtons
c 15 newtons
d. 20 newtons
e 25 newtons

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

The discovery of the electron as a subatomic particle was a result of

What accounts for an increase in the temperature of a gas that is kept at constant volume? a. energy has been removed as heat from the gas. b. energy has been added as heat to the gas. c. energy has been removed as work done by the gas. d. energy has been added as work done by the gas.
