Chapter 20, Problem 18QP

Interpretation Introduction

Interpretation:

The corresponding loss of mass in kg/s by the sun is to be determined, with given total energy output of sun.

Concept introduction:

Energy is the ability of a system to do work.

Equivalent energy is defined as the mass multiplied by the speed of light and its square.

Mass defect refers to difference in the mass of an atom and the sum of mass of protons, electrons, and neutrons present in the atom.

Energy is given by the expression as:

$\Delta E=\Delta m{\text{c}}^{\text{2}}$

Here, $\text{Δm}$ represents mass defect and $\text{ΔE}$ is thenuclear binding energy.
