A space probe on the surface of Mars sends a radio signal back to the Earth a distance of 7.03 x 107 km. Radio waves travel at the speed of light (3.00 108 ms). How many seconds does it take for the s?
70,300,000,000 divided by 30,000,000,000 equals 2.34333333 seconds.
Why is only 50 percent of the solar energy that reaches the outer atmosphere absorbed by Earths surface?
The Earth looks bright - thus much of the light reaching Earth is reflected back into space.
Where did friendship 7 land when it came back to Earth?
All of the Mecury space capsules were designed to land in the ocean, where they would be recovered by Navy helicopters.
Back in space?
Back in space is good name. Space is to mestirous and interesting subject. I think about space, star, planets, satellite and so many things
What is a scientific probe?
A probe is a spacecraft that travels through space to collect science information. ... Probes send data back to Earth for scientists to study. The First Probes. Sputnik 1 was the first probe to go into space.
What do space probes to send information back to earth?
radio
What do space probes use to send information back to earth?
radio
How did the Apollo 13 communicate back and forth from space to Earth?
They used a radio.
Speed of radio communication from earth to space?
Radio signals travel at the speed of light and all other forms of electromagnetic radiation. That means roughly 2.5 seconds to the moon and back, 8.7 minutes to Mars and back when it's closest to earth, 17 minutes to the sun and back, 9 years to the nearest star and back, etc.
Does a Space Telescope have an antenna?
Yes. Space telescopes require many radio antennas to transmit their observations back to Earth.
How spacewave came back to the earth?
Radio waves are often referred to as space waves because they have the ability to move through space. Radio waves are a type of electromagnetic radiation.
A space probe on the surface of mars sends a radio signal back to the earth, a distance of (9.03*10^7 km). Radio waves travel at the speed of light (3.00*10^8 m/s). How many seconds does it take for the signal to reach the earth?
0.301 seconds
How Do sunspote relate to the incidence of radio and tv disturebances?
The radiation emitted by sunspots ionizes the upper layers of the Earth's atmosphere. When that happens, radio waves (TV & radio) refract (bend) more in the ionization rather than shoot off into outer space as much. The radio waves by bending back to Earth travel much farther than if they just went straight. In the right conditions, these bent radio waves can bounce up off the Earth's surface and refract again in the ionized layers of the atmosphere, coming back down. In this ways, radio waves can travel long distances. The result is, that these long-distance radio waves come back to Earth where there are other radio and TV stations using the very same frequencies, and the long-distance radio waves interfere with the local programing.
If a ball is thrown in space and on earth which ball will travel the greatest distance?
Naturally the ball in space will travel the longest distance as long as it does not bump into something along the way. Gravity on earth will cause the ball thrown to fall back to earth.
How do we know that EM wave don't need a medium and can travel through vacuum?
Because of all the EM radiation we receive from the sun.Also . . .we can see the moonwe can see the sunwe can see other starswe can communicate by radio with astronauts on the moonwe can communicate by radio with the Curiosity on Marswe can communicate by radio with our space probes that have left the solar systemwe can bounce light and radio from Earth to moon and back to Earth
Does the ionosphere bend radio waves back toward the earth?
it refracts the radio waves back towards the earth
How do long radio signals get back down to earth?
How do THEY get back to earth?!
