The following charges are located inside a submarine: 2.75 μc, −9.00 μc, 27.0 μc, and −43.5 μc.(a) calculate the net electric flux through the hull of the submarine.(b) is the number of electric field lines leaving the submarine greater than, equal to, or less than the number entering it?

Answer with Explanation:

We know that by Gauss's Law

Where

is permitivity of free space

is the net charge in the hull

Part a)

Applying the given values we get

Part b)

Since the sign of the electric flux is negative we conclude that the electric field lines entering the submarine are more than the electric field lines leaving the submarine. Since negative sign implies that flux by negative charges is dominant.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
