Answer:
The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.
Answer:
Sun light takes 8.5 minutes to reach Earth.
Explanation:
Light travels in vacuum at constant speed
, so we can find the time it takes to travel the given distance from Earth to Sun using a kinematic equation.
Finding the time it takes for Sun light to reach us.
Using the kinematic equation
, we can solve for time t, which will give us

We can replace the equation with the given values, but before doing that, we need the values to be on SI units, thus the distance becomes

Replacing the values on the time equation give us

We get as result 510 seconds, then we must convert them in minutes.

So we can conclude that Sun light takes 8.5 minutes to reach Earth.
