(a)

Interpretation Introduction

Interpretation:

The power flux radiated by the Sun, in W/m2 is to be calculated.

Concept introduction:

The radiant energy is defined as the power per unit area. It is given by the expression as follows.

PA=σT4

In the above equation, PA is radiant energy, σ is Boltzmann constant and T is temperature. The value σ for a black body is 5.6705×108watt/meter2K4.

(b)

Interpretation Introduction

Interpretation:

The total power emitted by the Sun, in watts, having surface area 6.087×1012m2 is to be calculated.

Concept introduction:

The radiant energy is defined as the power per unit area. It is given by the expression as follows.
