Answer:A solenoid is a simple electromagnetic device consisting of a coiled electric wire, wrapped in a 3D circular pattern. When electric current is passed through the wire, the solenoid acts like a magnet with N and S poles at the ends of the coil.
When a ferromagnetic material rod is permanently placed inside the solenoid, the metal greatly increases the magnetic effect and becomes a permanent electromagnet. Moreover, it can also be used as an electrical switch by drawing in or pushing out a ferromagnetic material like an iron rod. Depending on the directions of the rod and the electrical current the switching action takes place.
Given figure represents the solenoid as electromagnet and the switching action.

Lol I just learned this, here's the short answer:
Large doses of X-Rays are known to cause cell damage and
cancer, so
<span>X-Ray technicians have to stand behind the shield. Here's the lengthy answer:
</span>
This is because the patient would only be exposed to the small
dose of radiation once, which is hardly harmful. However, radiographers
deal with this all day every day, which could mean that the small doses
could add up. This is why they stand behind a lead screen; the small
exposure to the X-Rays aren't harmful alone but frequent exposure could
begin to damage your cells and lead to potential genetic mutation. If a
patient is often in radiography (a long-stay patient for example), they
begin to wear lead aprons whilst being X-rayed in order to prevent the
risk of harm. Hope I answered correctly.
Answer:
3 sig figs total mass is 54.32g
Explanation:
It is 3 sig figs because that is the accuracy that Block A was measured to
Explanation:
There's a massive amount, just think of anything everyday. Like a table on the floor, or when your walking around and putting pressure on the floor. When you squeeze something which is solid. Anything like that will do.
