Under which set of circumstances will the pressure of a gas definitely increase? a) increasing the moles and increasing the volume of the gas. b) raising the temperature and reducing the volume of the gas. c) lowering the temperature and reducing the volume of the gas. d) raising the temperature and increasing the volume of the gas.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

as technology advances, new experiments often expose problems in accepted theories. c
