A. Calculate the acceleration of a skier heading down a 10.0º slope, assuming the coefficient of friction for waxed wood on wet snow. b. Find the angle of the slope down which this skier could coast at a constant velocity. You can neglect air resistance in both parts. Explicitly show how you follow the steps in the problem-solving strategies.

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?

If the pressure in a gas is doubled while its volume is held constant. true or false
