Out in the ocean, a wave crest 3.2 m high meets a wave trough from another direction which is 2.6 m deep. How high is the resulting wave??

Height of resulting wave = 0.6 meters

Explanation:

Let the higher wave (wave crest) be A while the lower wave (wave trough) be B.

Given the following data;

A = 3.2m

B = 2.6m

To find the height of the resulting wave;

Height = A + B

But the lower wave becomes negative because it is below i.e on the lower trough.

Height = 3.2 + (-2.6)

Height = 3.2 - 2.6

Height of resulting wave = 0.6 meters

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.
