Adding an intermediate switch is not an attractive choice to span the distance between two switches due to expense issues. It may have different ports.
<h3>What is a network switch?</h3>
A switch refers to a hardware tool capable of connecting different computer devices in a network.
A network switch can connect devices on a network by centralizing communications among many devices in a given local area network.
A switch may support different speeds for transmission of data (for example, one gigabit Gbps per second).

Answer;
B. Mass and energy are equivalent.
Explanation;
-Each of the letters of E = mc2 stands for a particular physical quantity.
E is the energy, m is the mass and c is the speed of light (m/s)
Energy = mass x the speed of light squared
-The equation E=mc2 explains nuclear fusion, how matter can be destroyed and converted to energy and energy can be converted back to mass. It explains the atomic energy produced by nuclear power plants and the atomic energy released by atomic bombs.
-The equation tells us that mass and energy are related, and, in those rare instances where mass is converted totally into energy, how much energy that will be.
Fractional distillation is the most efficient technique to separate solid benzoic acid mixed with a volatile alkyl halide liquid components.
<h3>Fractional distillation :</h3>
Separating a mixture into its constituent parts, or fractions, is known as fractional distillation. Chemical compounds are separated by heating chemical mixtures to a temperature at which one or more fractions of the mixture evaporate. Distillation is used to fractionate.
Boiling a mixture of liquids results in vapors rising up a glass tube known as a "fractionating column," which is followed by separation. The fractionating column, which is placed between the flask holding the mixture and the "Y" adaptor, improves the separation of the liquids being distilled.
<h3>Uses of fractional distillation :</h3>
Alcohol purification, desalination, crude oil refinement, and the creation of liquefied gases from air are all applications of distillation.
