8. The moon has about 1/6th the gravity of the Earth. How would the potential energy of an object be different on the moon if it
topjm [15]

The potential energy on the moon would be 1/6 of the potential energy on Earth

Explanation:

The potential energy of an object is the energy possessed by the object due to its position in a gravitational field, and it is given by

PE=mgh

where

m is the mass of the object

g is the strength of the gravitational field

h is the height of the object above the ground

In this problem, the potential energy of the object on the Earth is

PE=mgh

On the Moon, the gravity is

g'=\frac{1}{6}g

Therefore, if the same object (same mass) is placed at the same height h on the Moon, its potential energy would be

PE' = m(\frac{1}{6}g)h = \frac{1}{6}(mgh) = \frac{1}{6}PE'

Which of these objects has the largest volume?
motikmotik

Answer:

The balloon

Explanation:

Since there are 100 cm or 1000 mm in a meter, you can rewrite the dimensions in the following way:

A cube of metal with a volume of 10,000 mm^3

A spherical balloon with a volume of 50,000,000 mm^3

A sample of water with a volume of 1,000 mm^3

Therefore, the balloon clearly has the most volume. Hope this helps!
