<span>The total mass that should be placed in the right cap so
that the caps equilibrate at equal height is also 1 kg. if equilibrium should
be maintained the force in each side should cancel out, so to balance a 1kg
mass, a 1 kg mass should also be place on the opposite direction</span>
Answer:
The equilibrium temperature of the surface of the moon can be found by the formula as follows:

Where
is the solar constant and
is the Stefan's Boltzmann constant.

Thus, the equilibrium temperature of the surface of the moon is 273 K.
