A solid uniform cylinder with a radius of 0.3m and a mass of 12kg is free to rotate about its axis, which is supported by frictionless bearing a constant tangential force of 10N is applied to the cylinder calculate (i)the torque applies to the cylinder (ii) what's the angular acceleration of the cylinder (iii) what's the angular velocity of the cylinder 3 secs after the force applied.

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.
