The force of gravity pulls down on your school with a total force of 400,000 newtons. The force of gravity pulling down on your school would be exactly twice as much if your school: a Had twice as much mass b Was twice as tall c Had twice as much volume d Covered twice as much area

A) Had twice as much mass

Explanation:

Given that the force of gravity pulling down on school = 400,000 N

The force of force of gravity is the product of mass of the body and the acceleration due to gravity. The acceleration due to gravity is constant on the earth surface with a constant value of 9.8m/s²

Hence,

F = mg = 800N

F = force of gravity, m = mass of body, g =! acceleration due to gravity.

since g is constant, to have 2F, then mass has to be doubled, that is 2m(2 * mass)

it is b. absorbs thermal energy
