How does a fuse differ from a circuit breaker? O A. A fuse must be replaced after use, but a circuit breaker can be
reset.
OB. A fuse works by flipping open, while a circuit breaker melts.
O C. A fuse opens the circuit to stop current, but a circuit breaker
closes the circuit.
O D. A fuse works when it detects a high resistance, but a circuit
breaker works when it detects a high voltage.

A.  A fuse must be replaced after use, but a circuit breaker can be

reset.

Explanation:

A fuse works by actually melting, so there is physical damage that interrupts conduction of current due to lack of conductive material.

The circuit breaker is a switch operated automatically when there is excess flow of current. It interrupts that way the flow of current, but can simply get reset (back to its original close position) once the problem that caused the overflow of current in the circuit is found.

This better agrees with answer A in the list of possible choices.

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.
