Describe how fuses and circuit breakers protect against electrocution and household fires. how do you restore a broken circuit after the problem has been corrected?

Fuses: is a device that is designed to break the circuit when the current exceeds a certain level.

Circuit breaker: the circuit breaker “trips,” shutting off the current. Once the problem is solved, the circuit breaker can be reset and re close the circuit.

Explanation:

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.
