how long would it take a radio wave with a frequency of 7.25 x 10to the 5th to travel from Mars to earth if the distance is approx. 8.0 x 10 to the 7th?
If the distance is 8.0E7 WHAT? miles? km? feet? gallons?
distance = rate x time.
Radio waves travel at 3E8 m/s
Oh I am sorry, the distance between mars and earth is measured in kilometers.
Substitute into distance = rate x time and solve for time. You will need to change the distance from km to m or rate from m/s to km/s.
reverse the reciprocal and divide by 12 and measure by comcast remote. Then rub with lemon juice to remove stain. After, crack the egg with 2 fingers as that is the most effective way to do so. Last but not least, add 2 1/2 cups of ice tea vodka to take it all down. This should get you to your desired result.
To determine the time it would take for a radio wave to travel from Mars to Earth, we can use the equation:
time = distance / speed
The speed of a radio wave is the speed of light, which is approximately 3 x 10^8 meters per second.
Given:
Frequency of the radio wave (f) = 7.25 x 10^5 Hz
Distance (d) = 8.0 x 10^7 meters
First, we need to find the wavelength (λ) of the radio wave. The wavelength of a wave is given by the speed of light divided by the frequency:
wavelength = speed of light / frequency
wavelength = (3 x 10^8) / (7.25 x 10^5)
wavelength ≈ 413.79 meters
Now that we have the wavelength, we can calculate the time it would take for the radio wave to travel the distance from Mars to Earth:
time = distance / speed
time = (8.0 x 10^7) / (3 x 10^8)
time ≈ 0.2667 seconds
Therefore, it would take approximately 0.2667 seconds for a radio wave with a frequency of 7.25 x 10^5 Hz to travel from Mars to Earth.
