In 2003, NASA launched the rover Spirit onto the surface of Mars to explore our planetary neighbor. Near the end of January 2010, Mars was 99.33 million km away from Earth. Assume the speed of communication is at the speed of light, which is 300,000,000 m/s. If a researcher on Earth requested information from Spirit about its temperature, how long did the researcher have to wait for a reply after sending the request? Express your answer in the form minutes and seconds.You will enter minutes in part I and seconds in part II.
Enter minutes and seconds
"You will enter minutes in part I and seconds in part II"
How do you expect us to enter the values into your online webpage ?
no i need help and i will enter it
well,
300,000,000 m/s = 300,00 km/s
just the 99.33 million km by 300,000 km/s
that will be your answer is seconds, divide by 60 to get minutes, multiply the decimal part ONLY of your answer by 60 to get the seconds
thanks
To calculate the time it took for the researcher on Earth to receive a reply from the Spirit rover after sending the request, we need to determine the time it takes for the signal to travel from Mars to Earth.
First, we need to find the distance between Mars and Earth when the request was sent. We know that Mars was 99.33 million km away from Earth, but we need the distance in meters to match the speed of light.
Converting 99.33 million km to meters:
99.33 million km = 99,330,000,000 meters
Next, we need to calculate the time it takes for the signal to travel this distance at the speed of light.
Time = Distance / Speed
Time = 99,330,000,000 meters / 300,000,000 m/s
Time = 331.1 seconds
The time it took for the signal to travel from Mars to Earth is approximately 331.1 seconds.
To convert this time into minutes and seconds:
Minutes = 331.1 seconds / 60 seconds/minute
Minutes = 5.51 minutes
So, the researcher had to wait for approximately 5 minutes and 31.1 seconds for a reply after sending the request.
