F = 500N
S = 5m
T = 1.2s
----------------------------------
P = ?
We can use formula P = F * V, just because it was a smooth slide we can assume that average speed was V = S/T = 5 / 1.2 = 50/12
So the final answer would be:
P = F * V = 500 * 50/12
Are you sure those are correct numbers? The answer don't look nice :D
Answer:
All molecules of one substance are identical (exactly the same)(2)
Answer:
Explanation:
Gauss's Law says that the electric flux 
through a closed surface is directly proportional to the charge 
inside it. More precisely,
This means what is outside this closed surface 
does not contribute to the flux through it because field lines that go in must come out, <em>resulting a zero flux from an external charge. </em>
In our context, this means the charge 
which is outside the sphere will have zero flux through the surface; therefore, Gauss's law will only be concerned with charge 
which is inside the sphere; Hence,
Solving for gives
which is the charge inside the sphere.
