Questions & Step-by-Step Solutions
If the speed of light in a vacuum is approximately 3 x 10^8 m/s, what is its value in km/s?
Step 1: Understand that the speed of light is given as 3 x 10^8 meters per second (m/s).
Step 2: Know that 1 kilometer (km) is equal to 1000 meters (m).
Step 3: To convert from meters per second (m/s) to kilometers per second (km/s), you need to divide the value in m/s by 1000.
Step 4: Perform the calculation: 3 x 10^8 m/s ÷ 1000 = 3 x 10^5 km/s.
Step 5: Recognize that 3 x 10^5 is the same as 300000, so the speed of light in km/s is 300000 km/s.
Unit Conversion – Understanding how to convert between different units of measurement, specifically from meters per second (m/s) to kilometers per second (km/s).
