The charge on the left sphere negatively charged.
<h3 /><h3>What is charge?</h3>
Due to the physical property of electric charge, charged material experiences a force when it is subjected to an electromagnetic field. You might be electrically positive or negative. While similar charges repel one another, opposite charges attract.
In order for the neutral metal sphere and negatively charged metal rod to have the same potential, some negative charge must flow from the rod to the sphere in order for them to both have negative charges.
The sum of the negative charges in them would be equal to the initial negative charge in the rod since the entire charge is preserved.

The answer is A. conduction
C. It is C because it really is loose covering.
The coefficient of friction between the soap and the floor is 0.081
If Juan steps on the soap with a force of 493 N, this is her weight, W. This weight also equals the normal reaction on the floor, N.
We know that frictional force F = μN where μ = coefficient of friction between soap and floor.
So, μ = F/N
Since F = 40 N and N = W = 493 N,
μ = F/N
μ = 40 N/493 N
μ = 0.081
So, the coefficient of friction between the soap and the floor is 0.081
