The mass of an elephant on the moon
would be
a. less than its mass on mars.
b. more than its mass on mars.
c. the same as its weight on the moon.
d. none of the above

The correct answer is d. None of the above

Explanation:

The largest land animal on our planet is the African elephant. An elephant can weigh 6 tons, but not everywhere it is. If we could transport the elephant in a spaceship, its weight would be different on each planet.

On the Moon, the weight of an elephant would be reduced to one-sixth that on Earth, that is, it would weigh 1 ton. On the planets closest to Earth, Venus and Mars, their weight would be 5.4 tons on Venus and 2.25 tons on Mars.

If we move away, on the planet Jupiter the elephant would multiply by 2.5 its weight. In Neptune, its weight would increase by one tenth, reaching 6.6 tons, and in Uranus it would decrease by one tenth, weighing 5.4 tons.

10 years is the answer
