Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x 50 cm and x 50 cm. The charge densities on the planes are 50 nC/m2 and 25 nC/m2 , respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x 80 cm

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
