- 0.012 Au/min
- 0.12 Au/min
- 1.2 Au/min
- 12.0 Au/min
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Average distance between the earth and sun, is approximately $1.5 \times 10^{8} km$. Speed of light is $3.0 \times 10^{8} m / s.$
$\therefore$ Speed of light in astronomical unit per minute
$=0.12\, Au / \min$
$\therefore$ Speed of light in astronomical unit per minute
$=0.12\, Au / \min$

Physical World
The physical world includes the complications of the natural world around us. It is a type of analysis of the physical world around us to understand how it works. The fundamental forces that control nature are:
- Gravitational Force is a universal force that exists as an outcome of mutual attraction between any two objects with respect to their masses.
- Electromagnetic Force can be understood as the force that is present between the charged particles. The force is stated by Coulomb’s law.
- Strong Nuclear Force is the force that ties the protons and neutrons in a nucleus. Of all the elemental forces in nature, a strong nuclear force is the strongest as its name suggests.
- Weak Nuclear Force can only be noticed in some of the nuclear processes such as the beta decay of the nucleus.
