The document calculates the intensity of a radio station's power output of 200 watts at a distance of 2 miles. It determines the area of a spherical shell at that distance and uses it to find the intensity, resulting in an intensity of 1.53 x 10^-6 watts/m2. The calculations involve converting miles to meters and applying the formula for intensity.

A radio station has a power output of 200 watts. What is the intensit.pdf
- 1. A radio station has a power output of 200 watts. What is the intensity in watts/m2 at a distance of 2 miles from the station? A car has an interior volume of 3.5 m^3 and is at a temperature of 30 degrees C Solution 2) Intensity, I = Power/area = P/A So, for a distance of radius, r = 2 miles, the total area of spherical space: A = 4*pi*r^2 So, A = 4*pi*(2*1.61*1000)^2 = 1.303*10^8 m2 So, I = 200/(1.303*10^8) = 1.53*10^-6 W/m2
