5. A 4 kg ball that is moving straight upward has 17 J or kinelic energy and ils lolal mechanical energy is 25 J. a) Find the gravilalional polenlial energy of the ball.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

answer: a. same unit

explanation:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
