To say that one wave is out of phase with another is to say that the waves area) of different frequencies. b) of different amplitudes. c) of different wavelengths. d) out of step. e) all of the above

v=ir = 3x15 =45 v

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.
