The distance between the sun will exhaust all of its energy in about ten billion years. by that time, it will have radiated about 1.2x10^-44(joules) of energy. express this amount of energy in kilojoules

Explanation:

1 Joule () is equivalent to . So, we have to make the conversion:

Joules   KiloJoules

? ----------

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.
