How much time is required for reflected sunlight to travel from the Moon to Earth if the distance between Earth and the Moon is
mafiozo [28]

1.3 second of time will be required for reflected sunlight to travel from the Moon to Earth if the distance between Earth and the Moon is 3.85 × 105 km

<h3>What is Speed ?</h3>

Speed is the distance travelled per time taken. It is a scalar quantity. And the S.I unit is meter per second. That is, m/s

In the given question, we want to find how much time is required for reflected sunlight to travel from the Moon to Earth if the distance between Earth and the Moon is 3.85 × 10^5 km.

What are the parameters to consider ?

The parameters are;

  • The distance S = 3.85 × 10^{5} km
  • The Speed of Light C = 3 × 10^{8} m/s
  • The time taken t = ?

Speed = distance S ÷ Time t

Convert kilometer to meter by multiplying it by 1000

C = S/t

3 × 10^{8} =  3.85 × 10^{8} / t

Make t the subject of formula

t = 3.85 × 10^{8} / 3 × 10^{8}

t = 1.2833

t = 1.3 s

Therefore, 1.3 second of time will be required for reflected sunlight to travel from the Moon to Earth if the distance between Earth and the Moon is 3.85 × 105 km

A child is sledding. He starts at the top of the hill with a velocity of zero, and 3 seconds later he is speeding down the hill
Flauer [41]

Magnitude of acceleration = (change of speed) / (time for the change) =

                                             (12 m/s  -  0)   /   (3 sec)  =

                                               12/3  =  <em>4 m/s²</em>

What's a challenge question ?  Have we all passed the event horizon
and been spaghettified without knowing it ?
