The space probe Pioneer 11 was launched April 5,1973, and reached Jupiter in December 1974 traveling a distance of 998 million km. How long did it take an electromagnectic signal to travel to earth from Pioneer 11 when it was near Jupiter.
time=distance/veloctyoflight
distance is 998 million km
what is veloctyoflight
To determine how long it took for the electromagnetic signal to travel from Pioneer 11 to Earth when it was near Jupiter, we need to calculate the signal travel time based on the speed of light.
First, we need to know the distance between Earth and Jupiter when Pioneer 11 was near Jupiter. According to the question, Pioneer 11 traveled a distance of 998 million km from Earth to Jupiter.
Next, we need to calculate the time it takes for an electromagnetic signal to travel 1 kilometer. The speed of light in a vacuum is approximately 299,792 kilometers per second.
Now, we can calculate the signal travel time. Divide the distance between Earth and Jupiter (998 million km) by the speed of light (299,792 km/s):
Signal Travel Time = Distance / Speed
Signal Travel Time = 998,000,000 km / 299,792 km/s
Now, let's calculate the result:
Signal Travel Time ≈ 3327 seconds
Therefore, it took approximately 3327 seconds for the electromagnetic signal from Pioneer 11 to reach Earth when it was near Jupiter.
