Explanation:

The word LED means light emitting diode. It is an electronic component capable of emitting visible light transforming electrical energy into light energy. This process is called electroluminescence. LEDs are made of semiconductor materials. By replacing some of your atoms with others in a process called doping, you can control the color emitted by the device.

These devices typically operate at voltages between 1.5V and 3.3V. White LEDs, also known as RGB (red, green and blue) are made up of three LEDs: one red, one green and one blue . It is now common to find televisions that use LED technology on their panels.

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.
