Question

Think and ink.
1. A man does not eat for two days. The man feels very hungry.
However, he can still walk around. How is it possible?

Answer 1

Explanation:

While mass and weight are not interchangeable (weight is variable, while mass is constant), Cavendish's “weighing the world” experiment yielded a result of approximately 6 sextillion tons. The total mass of Earth's atmosphere is about 5.5 quadrillion tons, or roughly one millionth of Earth's mass.
