Find the intensity of electromagnetic radiation at the surface of the sun (radius r=R=6.96×105kmr=R=6.96×105km). Ignore any scattering of the waves as they move radially outward from the center of the sun.

.

Explanation:

Intensity of the electromagnetic radiation is given by

where is the distance from the EM source (the center of the sun, in our case), and is the power output of the sun and it has the value

Since the radius of the sun in meters is , the intensity of the electromagnetic radiation at the surface of the sun is

The intensity of the electromagnetic radiation at the surface of the sun is .

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
