Use the fact that the speed of light in a vacuum is about $3.00 \times 10^{8} \mathrm{m} / \mathrm{s}$ to determine how many kilometers a pulse from a laser beam travels in exactly one hour.
Added by Canary C.
Step 1
Given: Speed of light = $3.00 \times 10^{8} \, \text{m/s}$ To convert meters to kilometers, we divide by 1000: Speed of light in kilometers per second = $\frac{3.00 \times 10^{8}}{1000} = 3.00 \times 10^{5} \, \text{km/s}$ Show more…
