Question

The sun is continuously releasing nuclear energy in the form of radiation. This:

• A. prevents it from collapsing under its own weigth
• B. makes it ligher
• C. makes it heavier than the stars
• D. prevents light from other stars from reaching the sun

Answer 1

Answer: (A)

prevents it from collapsing under its own weigth

The sun has a huge mass and has great gravitational force as a result of its huge weight. Thus, it always has a tendency to collapse under self-weight and in order to prevent this it keeps on radiating energy in the form of radiation.
