Chapter 19, Problem 41E

Interpretation Introduction

Interpretation: The energy radiated by the sun into space every second is given. The rate at which mass is lost from the sun is to be calculated.

Concept introduction: Energy change of a system can be calculated by Einstein’s theory of relativity. When a system loses or gains energy, it also gains or loses a quantity of mass given by ${\text{E/c}}^{\text{2}}$.

To determine: The rate at which mass is lost from the sun.
