An iron that is properly used with rated voltage of 220V for 15 minutes consumes 720kJ of power. Let's calculate: a) Electric capacity of the iron

b) The current flowing through the iron and its resistance then.

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.
