57. Solar Power Collectors. This problem leads you through the
calculation and discussion of how much solar power can in
principle be collected by solar cells on Earth.
a. Imagine a giant sphere with a radius of 1 AU surrounding
the Sun. What is the surface area of this sphere, in square
meters? (Hint: The formula for the surface area of a
sphere is 4rr2.)
b. Because this imaginary giant sphere surrounds the Sun,
the Sun's entire luminosity of 3.8 × 1020 watts must pass
through it. Calculate the power passing through each
square meter of this imaginary sphere in watts per square
meter. Explain why this number represents the maximum
power per square meter that a solar collector in Earth
orbit can collect.
c. List several reasons why the average power per square
meter collected by a solar collector on the ground will
always be less than what you found in part b.
d. Suppose you want to put a solar collector on your roof. If
you want to optimize the amount of power you can
collect, how…
Based on what you know about main-sequence stars, select all of the correct statements from the following list.
1. Since the interiors of stars cannot be observed, there are no theories about their structure.
2. More massive stars are hotter and brighter.
3. The weight of a star must be balanced by internal pressure.
4. More massive stars live longer; they take longer to use up all their energy.
5. Stars change position on the main sequence throughout their lives.
6. Outward energy flow in a star is by conduction only.
A group of graduate students, bored during a cloudy night at a the observatory, begin to make bets about the time different stars will take to evolve.
If they have a cluster of stars which were all born roughly the same time, and want to know which star will become a red giant first, which of the following stars should they bet on?
a. a star that would type O on the main sequence star
b. a star about 1/2 the mass of our sun
c. a star about 8% the mass of our sun
d. all stars reach the red giant stage in roughly the same number of years
