Potential Energy = Mass * Gravitational Constant * Height
What We Don't Know: Potential Energy
What We Know:
Mass
Gravitational Constant (9.8 m/s)
Height
Ep = mgh
Ep = 4 * 9.8 * 2
Ep = 78.4 Joules
The Potential Energy of the Rock is 78.4 Joules, based on the given information! Hope this helps you!
Answer:
e. B and C
Explanation:
When the sun ignited in our solar system evaporation of the material closest to the sun took place. The low density material were pushed further. The rocks that remained formed the protoplanets. As, the early solar system was very hot parts of the protoplanets melted. This caused the melted material to flow towards the center of the planet. As the mass of the planet increases this causes more accretion which causes materials of different densities to mix.
