A rock had 100J of potential energy before it fell down a 100m high hill. After it fell halfway down the hill (50m) half of the potential energy was transferred to kinetic energy. How much potential energy and kinetic energy does the rock now have? (Make sure your units are in Joules)

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
