Use the fact that speed of light in a vacum is about 3.00×10 to the 8 m/s to determine how many kilometers a pulse from a laser beam travels in exactly 1.5 hour (s)
To determine how many kilometers a pulse from a laser beam travels in 1.5 hours, we can use the formula:
Distance = Speed × Time
First, we need to convert the speed of light from meters per second to kilometers per hour.
1 meter = 0.001 kilometers
1 second = 3600 hours (since there are 3600 seconds in an hour)
Therefore, the speed of light in kilometers per hour is:
Speed (km/h) = (Speed (m/s) × 0.001 km/m) × (3600 s/h)
Now, we can calculate the distance traveled by a pulse from a laser beam:
Distance (km) = Speed (km/h) × Time (h)
Let's substitute the values into the equation and solve for the distance:
Speed (km/h) = (3.00 × 10^8 m/s × 0.001 km/m) × (3600 s/h)
= 1.08 × 10^9 km/h
Distance (km) = 1.08 × 10^9 km/h × 1.5 h
= 1.62 × 10^9 km
Therefore, a pulse from a laser beam would travel approximately 1.62 billion kilometers in exactly 1.5 hours.
distance = speed * time
so, plug and chug
