1. in this experiment what force acts between the two coils? 2. when the two coils are attracting, how do you balance the upper coil? 3. what will you measure in this experiment? 4. if we increase the current through the coils, will the magnetic force increase or decrease? 5. if we increase the distance between the coils, will the magnetic field increase or decrease?

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.
