Question

The temperature of the sun varies from 10,900˚F on the surface to 27 billion ˚F at its core. Write these in scientific notation.​

Answer 1

→Answer :

Given: The surface temperature of the sun is T

0

and it is at average distance d from a planet. The radius of the sun is R.

To find the temperature at which planet radiates the energy.

Solution:

Let P be power radiated by the sun

Given, R is radius of the sun, d is average distance between sun and planet and T

0

is the surface temperature of the sun

if T is the temperature at which planet radiates the energy.

Energy received by the planet = WA=σT
