Two conducting parallel plates 5.0 × 10−3 meter apart are charged with a 12-volt potential
difference. an electron is located midway between the plates. the magnitude of the electrostatic
force on the electron is 3.8 × 10−16 newton.

calculate the magnitude of the electric field strength between the plates, in newtons per coulomb

Aball bearing at 220.0 °c is dropped into a cup containing 250.0 g of water at 20.0 °c. the water and ball bearing come to a temperature of 30.0 °c. what is the heat capacity of the ball bearing in j/°c? (hint: how are the algebraic signs of q related for the ball bearing and the water? )

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
