1. The gas in a cylindrical container occupies a volume of 45 cm^3 and exerts a pressure of 3.8 kg/cm^2. If the volume V varies inversely as the pressure P, find the pressure if the volume is reduced to 30 cm^3.

2. The intensity of illumination I of light varies inversely as the square root of the distance d from the light. At a distance of 40 m, a light has an intensity of 200 candela. Find the intensity of the light at a distance of 50m.
