Answer:
is; is not
Explanation:
The four-firm concentration ratio for newstands is 17 and for electric lamp makers it is 89. The HHI for newstands is 105 and for electric lamp makers it is 2 comma 850. The newstand market is an example of monopolistic competition. The electric lamp market is not an example of monopolistic competition
<h3>Answer;</h3>
- <em>The spheres develop opposite charges.
</em>
- <em>Electrons move from Sphere A to Sphere B.
</em>
- <em>The spheres are charged through induction.</em>
<h3><u>Explanation;</u></h3>
- <u><em>When a negatively charged rod is placed near two neutral metal spheres, the spheres will develop opposite charges, because the neutral metal spheres have both negative and positive charges. </em></u>From the basic law of electrostatics unlike charges attracts and like charges repel.
- Thus, <em><u>the sphere will develop opposite charges, electrons will move from Sphere A to sphere B,</u></em> hence we say that the spheres will be charged by induction such that sphere A will acquire a positive charge while sphere B will acquire negative charge.

It increases
Explanation:
A circuit's resistance increases as more resistors are added to it in series.
Series connection of circuit provides an additive increase in the resistance offered by the overall circuit.
A resistor is a device in a circuit that impedes the flow of electric current. It simply uses electric current.
Examples are bulbs, radio, television.
The more of these devices connected one to another in series, the more the resistance increases.

The heat transferred by the steam to the skin is given by
where
m is the mass of the steam
is the latent heat of vaporization.
In our problem, the mass of the steam is (converting into kg)
while the latent heat of vaporization of the steam is
Substituting into the previous formula, we find the heat transferred to the skin:
