Answer:
Coefficient of friction is the ratio of friction force to normal force.
μ = F/N
Answer:
The time rate of change of the electric field between the plates is
Explanation:
From the question we are told that
The radius is 
The distance of separation is 
The current is 
Generally the electric field generated is mathematically represented as

Where
is the permitivity of free space with a value

So the time rate of change of the electric field between the plates is mathematically represented as

But 
So

substituting values


Answer:
2: 20HZ 3:audiable
Explanation:
i guessed and it told me i was right
The total charge on the interior of the conductor is zero.
The total charge on the exterior of the conductor is 8q.
<h3>
Total charge on the interior</h3>
Due to large number of electrons available for conduction in a conductor, most of the electrons moves to surface leaving zero net charge inside the conductor.
Thus, the total charge on the interior of the conductor is zero.
<h3>T
otal charge on the exterior</h3>
The total charge on the exterior of the conductor is calculated as follows;
Q = q + 7q = 8q
Thus, the total charge on the exterior of the conductor is 8q.
