Please help 4. What are the lowest points on a transverse wave called?
a. Crests
b. troughs
C. compressions
d. rarefractions

5. Any substance that a wave moves through is called a
a. medium
b. vibrate
C. crest
d. frequency

4. Low points are called troughs

5. Medium: substance through which a wave can travel

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
