Ariel skiing involves speeding down a steep ramp that curves sharply upward at the end to launch the skiers into the air. Once airborne skiers twist and turns into Contacts combinations to score points in the competition. Consider an aerial launch ramp that has a final launch slope of 52.9° above the horizontal. Given this angle a skier flies to 17.1 m above the end of the ramp. From this information determine the skiers launch speed

Which statement best describes resistance? resistance is a. how well a current will flow in a material and is measured in volts. b. how well a material conducts an electrical charge and is measured in ohms. c. the ability of a material to attract a positive charge to create a current. d. the ability of a material to repel neutral charges and is measured in ohms.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
