There are no advantages or disadvantages over which type of junction box to be used on electrical wiring. As long as the junction box is of an approved type (CSA or UL approved). It is cost or location which dictates which boxes will be used. PVC boxes for home wiring are the cheapest. Aluminium or steel are usually used in rigid or EMT conduit systems. PVC again when the conduit system involves underground wiring. In large electrical installations it is the electrical engineer that states what the conduit system type is and what type of electrical junction boxes that must be used.

A 5.0kg box is pushed across the floor with a force of 32N What is the frictional force on the box if the boxs acceleration is 3.6mS2?
Frictional force equals 14 Newtons Fnet = Fp - Ff so rewriting the equation gives us: Ff = Fp - Fnet (Fnet is net force, Fp is force of push, and Ff is frictional force) We already know that Fp is 32 N and we can find Fnet by using Newton's Second Law: F = ma Fnet equals 5 kg times 3.6 m/s2 = 18 N So Ff = 32 N - 18 N which equals 14 N
Mathias Schleiden and Theodor Schwann famous for?
They co founded cell theory. In 1836/7 they showed that when air goes through red-hot glass tubes, or through sulphuric acid, the amount of oxygen stays the same but living things are killed. They passed this sterile air through boiled broth and nothing grew. then when they exposed the broth to normal air, moulds and microbes soon grew. By doing this they proved that the current theory of spontaneous generation was wrong. However, scientists claimed that they had destroyed something important in the air. ( spontaneous generation= the theory that living thing can be made by nonliving things (e.g. fish can be made from things in the river like mud))
