12. An object in uniform circular motion has a constant velocity while experiencing centripetal acceleration.
13. An object travelling in uniform circular motion experiences an outward centrifugal force that tends to pull
the object out of the circular path.

increase as the applied force increases.

In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using?
