A 1500 kg car sits on top of a car carrier truck 2.5 meters above the ground how much potential energy does the car have

36,787.5 Joules

Explanation:

Potential Energy = mass * acceleration due to gravity * height

U = mgh

We know the following:

   mass = m = 1,500 kg

   acceleration due to gravity = g = 9.81 m/

   height = h = 2.5 m

When we substitute each value into the formula we get the following:

U = 1,500 kg * 9.81 m/ * 2.5 m = 36787.5 kg = 36,787.5 Joules

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
