Answer:
Explanation:
We shall apply Gauss's theorem to calculate the electric flux through a closed surface due to charge contained in side
Total charge inside surface = zero
So total electric flux through closed surface will be zero.
or electric flux going out = electric flux coming in
(a) The electric field is zero everywhere on the surface. True
(b) The electric field is normal to the surface everywhere on the surface. - false
(c) The electric flux through the surface is zero. True
(d) The electric flux through the surface could be positive or negative - false
(e) The electric flux through a portion of the surface might not be zero - True
When you are sitting in a chair your body exerts a FORCE, the chair exerts the SAME force back.
B. When the ball is rolling across the floor at a constant velocity, the change in its kinetic energy is zero.
<h3>
What is change in kinetic energy?</h3>
The change in kinetic energy of an object is the dereference between the final kinetic energy and the initial kinetic energy.
ΔK.E = K.Ef - K.Ei
ΔK.E = 0.5m(vf² - vi²)
where;
- K.Ef is the final kinetic energy
- K.Ei is the initial kinetic energy
- vf is final velocity
- vi is initial velocity
At constant velocity, the initial velocity and final velocity are equal.
ΔK.E = 0.5m(0) = 0
Thus, when the ball is rolling across the floor at a constant velocity, the change in its kinetic energy is zero.

Because solar panels are man made so they can shut down, not move, break, etc...? Don’t judge me, it’s just a guess.
