Period of a simple pendulum = 2π √(L/G)
(360s/100) = 2π √(1.2m/G)
1.8s / π = √1.2m / √G
√G · (1.8s/π) = √1.2m
√G = (π · √1.2m) / 1.8s
Square each side:
G = π² · 1.2m / 3.24 s²
G = (1.2 · π² / 3.24) m/s²
G = 3.66 m/s²
So I just went and looked up Mars gravity. Floogle says it's 3.711 m/s² there.
That seems awfully close ... only 1.4% greater than our astronauts measured.
You don't suppose . . . . .

As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy.
Answer:
Yes, the battery's store of chemical potential energy will have decreased. Work is done on the positive charge in moving that charge to the battery's positive terminal. Chemical potential energy is converted into electrostatic potential energy in pushing the positive charge up a voltage gradient. Hope this helps!

More massive than Jupiter
