Question

What effect does the swirling of the plasma gas have?

Oa.It causes the sparks to spin outward scattering them around the shop floor.
Ob.It causes the stream to become more dense.
Oc.Centrifugal force causes the stream to spread out or even causes it to go off.
Od. The wider plasma arc is best used for gouging.

Answer 1

The swirling of the plasma gas causes the stream to spread out or go off due to centrifugal force acting on it.

Step-by-step explanation:

The swirling of the plasma gas has the effect of causing the stream to spread out or even causing it to go off. This is due to the centrifugal force acting on the plasma gas as it swirls in a circular motion. Centrifugal force is the force that pushes an object away from the center of rotation, and in this case, it causes the plasma gas stream to spread outwards.

For example, when the plasma gas is swirled in a plasma cutter, the centrifugal force causes the plasma arc to widen, which is used for gouging, a process of removing metal by melting it with a wider arc.

So, the correct answer is (Oc) Centrifugal force causes the stream to spread out or even causes it to go off.
