Astudent of mass m = 89 kg takes a ride in a frictionless loop-the-loop at an amusement park. the radius of the loop-the-loop is r = 19 m. the force due to the seat on the student at the top of the loop-the-loop is fn = 142 n and is vertically down. what is the apparent weight of the student at the bottom of the loop-the-loop?

What is a carrier wave and how does it affect what you hear on the radio

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

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.
