An electric appliance is connected by wires to a 240-volt
source of voltage. If the combined resistance of the appliance
and wires is 12 ohms, how much current is flowing through the
circuit?
a
12 amps
25 amps
20 amps
18 amps

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.
