Textbook Question
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?

An object is propelled off of a platform that is 75 feet high at a speed of 45 feet per second (ft./s). The height of the object off the ground is given by the formula h(t) = - 16t+45t+75, where h(t) is the object's height at time (t) seconds after the -16 object is propelled. The downward negative pull on the object is represented by Solve for t.arrow_forward
