A strong lightning bolt transfers 32 C to Earth. If each water molecule donates one electron, what mass lost an electron to lightning? One mole of water has a mass of 18 g.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The pressure proportional to the area a- inversely b- directly c- increase d-decrease
