Remove the positive charge by dragging it back to the box at the bottom, and drag a negative charge (blue) toward the middle of the screen. determine how the electric field is different from that of the positive charge. which statement best describes the differences in the electric field due to a negative charge as compared to a positive charge?

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.
