The distance to mars is 7.5 x 1010 meters how long does it take for a radio signal from mars pathfinder to be received by nasa on earth?

light travels at approximately 300,000,000 m/s, so to pass 7.5*1010 meters it would take:
7.5*1010/300,000,000=250 seconds
= 4.167 minutes
P.S. Mars is not that close, in real life the signal takes about ten minutes to travel either way.

But note that the actual distance from Mars to Earth is tremendously larger than 8 kilometers.

How are signal received in radio station?
transmissions
What does a pre amp do for a cb radio?
A preamp intensifies the signal being received.
What radio frequency is 89.0?
The wavelength of a signal at 89.10 MHz is 3.37 meters. Divide the speed of light, which is about 300,000,000 meters per second, by 8,910,000.
Does the t.v use radio waves?
Yes. A TV set is a radio receiver.Some of the information it receives on the signal is intended to be heardand is sent to the loudspeaker.Other information received from the signal is intended to be seen and isdisplayed on the screen.
If a spacecraft is approaching the earth relative to the radio signals it send out the signal received on the earth have?
Shorter wavelength, higher frequency.
Television signal cannot be received beyond a particular distance because?
curvature of earth
Where is your turn flasher located on a 2000 Pathfinder?
The 2000 Nissan Pathfinder turn signal flasher relay switch is located behind the drivers side dashboard. The turn signal flasher switch will be above the gas pedal.
What number in the fuse box of 1996 pathfinder is the turn signal?
it should be number four, a fifteen amp fuse
How hub handles a signal received in one port?

What is the maximum distance a IrDa device can send a signal to another IrDa device?
The maximum distance an IrDA device can trasmit is 1 meter. The effective range between two IrDA devices is 2 meters.
What number in the fuse box of 1997 pathfinder is the turn signal?
The Turn signal Fuse should be number 11 (7.5Amp) in the fuse box. Hazard Lights are on number 14 (15Amp).
Where is the turn signal flasher unit on a 1996 Nissan Pathfiner?
The 1996 Nissan Pathfinder turn signal flasher unit is located beneath the drivers side dashboard. The turn signal flasher unit will be above the brake pedal.
What is the frequency of a signal whose wavelength is 1.5 meters?
The answer will depend on what type of signal it is: acoustic, electromagnetic and in what medium the signal is propagated.
What is radar duplexer?
duplexer is the device that can separated the trasmitted signal and received signal.
How many meters long is a wavelength that measures 10 squared m?
Wavelength is a measure of distance not area. It is the distance traveled by a signal from a Zero state to a Plus One state back through Zero to Minus One and returning to Zero.
What effect will increasing the required transmission distance have on transmitting the signal clearly?
Increasing the required transmission distance of a signal will have a negative effect on the clearness of the signal. As the source is moved farther away from the receiver, a weaker signal will be present.
What are the ratings and certificates for No Signal - 2009?
No Signal - 2009 is rated/received certificates of: Australia:MA
