If an object with 80 j of gravitational potential energy is raised twice as high, what would be its new gravitational potential energy? a. 100 j
b. 160 j
c. Can't be calculated without
knowing its weight.

The gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy. And like this.

So, the answer is b. 160J

i got something better   a catchphrase here it is

ahem  

ahem

what the squwock

explanation:

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
