What is the intensity in W/m2 of a laser beam used to burn away cancerous tissue that puts 374 J of energy into a circular spot 2.00 mm in diameter in 4.67 s? Compare this to the average intensity of sunlight (about 700 W/m2).
answer blank times 10^7
The intensity of solar radiation at the top of the Earth’s atmosphere is 1 370 W/m2. Assuming 60% of the incoming solar energy reaches the Earth’s surface and you absorb 50% of the incident energy, make an order-of-magnitude estimate of the amount of solar energy you absorb if you sunbathe for 60 minutes.
The distance between Planet X and a star is 1.8 x 1011 m. At the surface of Planet X, the average intensity of the radiation from the star is 13440 W/m2. If the star radiates isotropically, which of the following is the average power of the star?
a. 7.64 x 1024 W
b. 5.47 x 1027 W
c. 9.69 x 1026 W
d.4.95 x 1028 W
