7. Reina is making museum exhibits about two different rock types. How could energy have played a role in the different rock types forming?

Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces.

Explanation:

Different sources of energy are required in the formation of rocks. A source of energy like the sun is vital in the facilitation of processes pertaining to rock formation that occur on the surface of the earth. Some of these processes include; erosion and weathering.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
