A radio signal travels at 3.00 ⋅ 108 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54 ⋅ 107 meters? Show your work.
We can start by using the formula:
distance = speed × time
In this case, the distance we want to calculate is the distance from the satellite to the surface of the Earth, which is the sum of the radius of the Earth and the height of the satellite above it:
distance = radius of Earth + height of satellite
distance = 6.37 × 10^6 + 3.54 × 10^7
distance = 4.18 × 10^7 meters
The speed of the radio signal is given as 3.00 × 10^8 meters per second, so we can set up the equation:
4.18 × 10^7 = 3.00 × 10^8 × time
Solving for time, we get:
time = distance / speed
time = 4.18 × 10^7 / 3.00 × 10^8
time ≈ 0.139 seconds
Therefore, it will take approximately 0.139 seconds for a radio signal to travel from the satellite to the surface of the Earth.
To calculate the time it takes for a radio signal to travel from a satellite to the surface of the Earth, we can use the following formula:
Time = Distance / Speed
In this case, the distance is the height of the satellite from the surface of the Earth, which is 3.54 ⋅ 10^7 meters, and the speed is the speed of light, which is approximately 3.00 ⋅ 10^8 meters per second.
Plugging the numbers into the formula:
Time = 3.54 ⋅ 10^7 meters / 3.00 ⋅ 10^8 meters per second
Dividing 3.54 ⋅ 10^7 by 3.00 ⋅ 10^8 gives us:
Time ≈ 0.118 seconds
Therefore, it will take approximately 0.118 seconds for a radio signal to travel from the satellite to the surface of the Earth.
To calculate the time it takes for a radio signal to travel from a satellite to the surface of the Earth, we can use the equation:
Time = Distance / Speed
In this case, the distance is the height of the satellite above the Earth's surface, which is 3.54 ⋅ 107 meters. The speed of the radio signal is given as 3.00 ⋅ 108 meters per second.
Plugging these values into the equation, we get:
Time = (3.54 ⋅ 107) meters / (3.00 ⋅ 108) meters per second
Simplifying, we get:
Time = 0.118 seconds
Therefore, it will take approximately 0.118 seconds for a radio signal to travel from the satellite to the surface of the Earth.
