Aphysics major is cooking breakfast when he notices that the frictional force between the steel spatula and the teflon frying pan is only 0.350 n. knowing the coefficient of kinetic friction between the two materials (0.04), he quickly calculates the normal force. what is it (in n)?

Around faucet handle is part of a(n) a. lever b. screw c. inclined plane d. wheel and axle

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

You can watch static electricity in action by rubbing an inflated balloon against your hair. your hair will actually stand on its end! it does this because each hair becomes charged, and they all repel one another.
