1. A star such as our Sun will eventually evolve to a “red giant” star and then to a “white dwarf” star. A typical white dwarf is approximately the size of Earth, and its surfacetemperature is about 2.5×10 3K. A typical red giant has a surface temperature of 3.0×104 K and a radius ~100,000 times larger than that of a white dwarf.a) What is the average radiated power per unit area by each of these types of stars?b) What is the ratio of total power radiated from the white dwarf over the power of the red giant

2. Can we Estimate the Solar Constant? A result from theoretical physics, known as the Stefan-Boltzmann law, states that the total power radiated by a blackbody at temperature T (K) per unit surface area is given by E=GT* where E is radiated power per unit surface area of the blackbody and o is the Stefan-Boltzmann constant equal to 5.67 x 10* Wm?K*. Let's assume that the sun is a perfect blackbody at T= 5783 K and apply the laws of energy conservation to estimate the average incidence of solar energy [W/m] arriving at the top of Earth's atmosphere (we call that incident energy the solar constant). Compare your calculated estimate of the solar constant to that commonly used to model the sun. Assuming the following constants: d = 1.39e9 m=Diameter of the sun de = 1.27e7 m = Diameter of the earth Res = 1.49el1 m = Mean earth-to-sun distance (HINT: use this distance as the radius of a sphere centered on the sun).

5. It is 5.0 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h (which uses up energy at the rate of 700 W), or you could walk it leisurely at 3.0 km/h (which uses energy at 290 W). Which choice would burn up more energy, and how much energy (in joules) would it burn? Why is it that the more intense exercise actually burns up less energy than the less intense exercise?
