The diagram below shows data about five satellites orbiting planet X.
6. Which satellite likely experiences the greatest gravitational force, and astronauts will likely weigh the most on these planets?
a. Satellite A
b. Satellite B
c. Satellite C
d. Satellite D
e. Satellite C and D

c. C
d. D
This image shows a candle before (A) and after it is lit (B).
8. Compare the amount of chemical potential energy in A to the chemical potential energy in B.
a. Candle A and B have equal potential energies, because energy is not created or destroyed.
b. Candle A has less potential energy.
c. Candle B has less potential energy.
d. None of the above.
9. When the candle is lit, is energy destroyed?
a. Yes, because the fire burns the potential energy of the wax, destroying the potential energy.
b. Yes, because the fire burns the potential energy of the wick, destroying the potential energy.
c. No, the energy changes forms from chemical potential to thermal kinetic, but the total amount of energy is the same.
d. No, the energy changes forms from chemical potential to thermal potential but the total amount of energy is the same.
