Chapter 15, Problem 71GP
A dark blue cylindrical bottle is 22 cm high and has a diameter of 7.0 cm. It is filled with water. The bottle absorbs 60% of the light that shines on it as it lies on its side in the noonday sun, with intensity 1000 W/m2. By how much will the temperature of the water increase in 5.0 min if there’s negligible heat loss to the surrounding air?

A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail." Suppose a sail of area A = 6.40 ✕ 105 m2 and mass m = 4,900 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1,370 W/m2.
A) If the solar sail were initially in Earth orbit at an altitude of 360 km, show that a sail of this mass density could not escape Earth's gravitational pull regardless of size. (Calculate the magnitude of the gravitational field in m/s2.)
B) What would the mass density (in kg/m2) of the solar sail have to be for the solar sail to attain the same initial acceleration of 1193 µm/s2.
The Intensity of solar radiation at the Earth's orbit is 1370 W/m2. However, because of
the atmosphere, the curvature of the Earth, and rotation (night and day), the actual
intensity at the Earth's surface is much lower. At this moment, let us assume the
intensity of solar radiation is 575 W/m2. You have installed solar panels on your roof to
convert the sunlight to electricity.
If the area of your solar panels is 4 m2, How much power is incident on your array?
Watts
Submit Answer
Tries 0/2
Unfortunately, solar panels are only about 20% efficent...Only 1/5 of the light is
converted to electricity. This being the case, how much electrical power are you
actually producing for your home at this moment?
Watts
Betelgeuse, a red-giant star in the constellation Orion, has a peak in its radiation at a frequency of 3.09 X 10^14 Hz. What is the surface temperature of Betelgeuse?

Your body emits a good deal of thermal radiation; a typical human body has a surface area of 1.8 m2, a surface temperature of 30∘C, and an emissivity e = 0.97 at infrared wavelengths.
