Problem 81AE

Problem 81AE

The Sun radiates energy into space at the rate of 3.9 * 1026 J/s.

(a) Calculate the rate of mass loss from the Sun in kg/s.

(b) How does this mass loss arise?

(c) It is estimated that the Sun contains 9 × 1056 free protons. How many protons per second are consumed in nuclear reactions in the Sun?

Step-by-Step Solution:
Step 1 of 3

Week 2 Lecture 4 9/7/16 Mass spectrometry - Mass spectrometry is how we determine the percentages of each naturally occurring isotope - Magnetic field separates ions based on ratio of mass to charge Uncertainty and Significant Figures - When a measurement is made, there is always some uncertainty, because we can only approximate the measurement - Cost of measurement, different measuring tools cost different amounts the more accurate of the measurement or further out in decimal places, the more expensive the device. - This last digit is an estimate and is said to be uncertain
