Answer:
the earliest year that Earth could expect to receive a return message =2189 year
Explanation:
Given that the distance from the earth to the source where the radio signals is 95 light years. The time taken by the signal to receive a return message when the signal sent toward Procyon in 1999 is :
1999 + 2(95)
=2189
Thus; the earliest year that Earth could expect to receive a return message =2189 year
The earliest year that Earth could expect to receive a return message will be 2189 years.
What is a light-year?
The distance traveled by light in one year is measured in light-years. Light travels through interstellar space at a speed of 186,000 miles per second.
The given data in the problem is;
d is the distance between Earth and the source of radio transmissions =95 light-years.
The year when the signal was transmitted toward Procyon was 1999
t is the time it took for the signal to get a response message =?
So the time it took for the signal to get a response message is found as;
[tex]\rm t= 1999 + 2 \times 95 \\\\ \rm t=2189 \ years[/tex]
Hence the earliest year that Earth could expect to receive a return message will be 2189 years.
