Use the fact that the speed of light in a vacuum is about 3.00 108 m/s to determine how many kilometers a pulse from a laser beam travels in exactly 4.9 hour(s)
This is a duplicate question. The answer remains the same.
To determine the distance traveled by a pulse of light from a laser beam in 4.9 hours, we need to use the given speed of light in a vacuum.
Step 1: Convert the speed of light from meters per second to kilometers per hour.
We know that 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds.
Speed of light in kilometers per hour = (Speed of light in meters per second) * (3600 seconds/hour) * (1 kilometer / 1000 meters)
Speed of light in kilometers per hour = 3.00 * 10^8 m/s * 3600 s/h * (1 km / 1000 m)
Speed of light in kilometers per hour = 3.00 * 10^8 * 3600 / 1000 km/hr
Speed of light in kilometers per hour ≈ 1.08 * 10^9 km/hr
Step 2: Calculate the distance traveled by the pulse of light in 4.9 hours.
Distance = Speed * Time
Distance = (1.08 * 10^9 km/hr) * (4.9 hours)
Distance ≈ 5.29 * 10^9 kilometers
Therefore, a pulse from the laser beam travels approximately 5.29 * 10^9 kilometers in exactly 4.9 hours.
