Suppose an electrical wire is replaced with one having every linear dimension doubled (i. e., the length and radius have twice their original values). How is the resistance of the wire affected?

a. The wire has the same resistance as before.

b. The wire has more resistance than before.

c. The wire has less resistance than before.

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.
