A car is accelerating at 5.0 km/hr/sec. Explain what is happening to the car.

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? )

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v
