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 ×  km km
- The Speed of Light C = 3 ×  m/s m/s
Speed = distance S ÷ Time t
Convert kilometer to meter by multiplying it by 1000
C = S/t
3 ×  =  3.85 ×
 =  3.85 ×  / t
 / t
Make t the subject of formula
t = 3.85 ×  / 3 ×
 / 3 × 
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

Magnitude of acceleration = (change of speed) / (time for the change) =
                                             (12 m/s  -  0)   /   (3 sec)  =
                                               12/3  =  <em>4 m/s²</em>

Answer:
False
Explanation:
Vector has a magnitude and direction.
A scalar is just a magnitude or size.
