Suppose an intelligent society capable of receiving and transmitting radio signals lives on a planet orbiting Procyon, a star 95 light years away from Earth. If a signal were sent toward Procyon in 1999, what is the earliest year that Earth could expect to receive a return message?

Respuesta :

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.
