Q47P - Fundamentals Of Physics

Question

An astronomical unit (AU) is the average distance between Earth and the Sun, approximately ${}^{\mathbf{1}\mathbf{.}\mathbf{50}\mathbf{\times }{\mathbf{10}}^{\mathbf{8}}\mathbf{ }\mathbf{km}}$ . The speed of light is about ${}^{\mathbf{3}\mathbf{.}\mathbf{0}\mathbf{\times }{\mathbf{10}}^{\mathbf{8}}\mathbf{ }\mathbf{m}\mathbf{/}\mathbf{s}}$. Express the speed of light in astronomical units per minute.

Step-by-Step Solution

Answer

The speed of light in astronomical units per minute is ${}^{\mathbf{0}\mathbf{.}\mathbf{12}\mathbf{ }\mathbf{A}\mathbf{.}\mathbf{U}\mathbf{.}\mathbf{/}\mathbf{min}}$

Step 1: Given data

Step 2: Understanding the unit conversion

Unit conversion is the conversion between different units of measure for the same quantity, usually through multiplier conversion factors.

Step 3: Determination of the speed of light

The speed of light in astronomical units per minutes is, 

Thus, the speed of light in astronomical units per minute is${}^{\mathbf{0}\mathbf{.}\mathbf{12}\mathbf{ }\mathbf{A}\mathbf{.}\mathbf{U}\mathbf{.}\mathbf{/}\mathbf{min}}$.
