Two coils have mutual inductance M = 4.15×10−4 H. The current i1 in the first coil increases at a uniform rate of 250 A/s. (a) What is the magnitude of the induced emf in the second coil? (b) Suppose that the current described is in the second coil rather than the first. What is the magnitude of the induced emf in the first coil?

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.
