How much kinetic energy does 2200kg car have if it is moving at 35m/s

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? )

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Explain what happens at the saturation point when adding salt to water at room temperature.
