Chapter 8, Problem 21SEQ
Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
*21. The Lifetime of the sun. The Sun’s Mass is about 2 Ă— 1030 kg. ; This mass was about 70% hydrogen when the sun formed, with about 13% of this hydrogen available for eventual in the core.
a. Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the Sun.
b. The Sun fuses about 600 billion kilograms of hydrogen each second. Based on your result from part a, calculate how long the Sun’s initial supply of hydrogen can last. Give your answer in both seconds and years.
c. Given that our solar system is now about 4.6 billion years old, when will the Sun run out of hydrogen for fusion?

For example, cams open and close the valves in your car engine to admit gasoline vapor to each cylinder and to allow the escape of exhaust. The principle is illustrated in the figure below, showing a follower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of a rotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, between the pushrod and the wedge, or between the rod and the guide through which it slides. When the wedge is pushed to the left by the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, the motion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of 0 = 15.0°. Suppose you want the wedge and the rod to start from rest and move with constant acceleration, with the rod moving upward 1.00 mm in 8.00 ms. Take m…arrow_forward
