It’s voltage can easily be modified and it allows power to be transmitted at a high voltage rate before being lowered to a smaller voltage rate to be safe.
Answer : Time taken for the light to reach earth is 
Explanation :
Given that,
Speed of Ultraviolet light, 
Distance covered by the light, 
We have to find the time taken (t) by the light to reach on the surface of earth.
t = 133333333.333 seconds
or
Hence, this is the required solution.
When the voltage is turned on and the droplet either rises or falls, the type of forces which are acting on the droplet are:
1) Gravitational force,
2) Electrical repulsion
<span>When the drop rises, it means that the upward electrical force is acting on it and a gravitational force is acting in downward direction. But in this case, the upward electrical force will be greater than the downward gravitational force.</span>
