Askier is pulled up a slope at a constant velocity by a tow bar. the slope is inclined at 21.5 ° with respect to the horizontal. the force applied to the skier by the tow bar is parallel to the slope. the skier's mass is 55.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.212. find the magnitude of the force that the tow bar exerts on the skier.

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
