Kal-El's mass on Krypton is 120 kg. If the gravitational force on Krypton is, I mean, was 4 times greater than that of Earth's, his mass would be:

• 120 kg

• 480 kg

• 30 kg

• 60 kg

If an astronaut has a mass of 88 kg on the Earth, her mass up in orbit on the International Space Station would be:

• 88 kg

• 0 kg

• 44 kg

• You can't tell because she would be weightless.

On Earth, SpaceGodzilla has a mass of approximately 23,000 kg. If the gravity near the black hole when he came from is 1,000,000 times that of Earth's, his mass at the black hole is:

• 23,000 kg

• 23,000,000,000 kg

• Infinite since he's near a black hole.

• Objects have no mass when they're in space.
