A sinusoidal electromagnetic wave from a radio station passes perpendicularly through an open window that has area of 0.500 m2. At the window, the electric field of the wave has an rms value 0.0300 V/m. How much energy does this wave carry through the window during a 30.0-s commercial?

1/0.14nm = 10^10/1.4 a lot

it has to be b, about 97 percent.

3. dark matter

empty space could also be a simple vacuum

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
