Question

Planet Tatoone is about 1.7 AU from its Sun. Approximately how long will it take for light to travel from the Sun to Tatoone in minutes? Use 3 × 108 m/s for the speed of light.

Answer 1

Answer:

The value is   $t = 14.129 \ minutes$    

Explanation:

From the question we are told that

  The distance of planet Tatoone is  $d = 1.7 \ AU = 1.7 *1.496* 10^{11}=2.543*10^{11} \ m$

   The  speed of light is  $c = 3.0*10^{8} \ m/ s$

Generally the time taken is mathematically represented as

     $t = \frac{d}{c}$

=> $t = \frac{2.543*10^{11}}{3.0*10^{8} }$

=>    $t = 847.7 \ s$

Now converting to minutes

       $t = \frac{847.7}{60}$

   =>     $t = 14.129 \ minutes$
