Inside the "holes" are springy brass fingers that grip the plug prongs when you insert the wall plug, making connection with your home's electrical system.
If it's an outlet that's round with many holes it is probably the drain in the sink.
What's the question? The holes on the back of the outlet are for inserting the wire and to release it so you can pull the wire back out. There should be a round and a rectangle one for each side terminal. They only accept 14 gauge wire, not 12 gauge. Older one would accept both, but not for several years. Wire goes in the round hole and you insert something such as a small nail in the release hole and push in and then pull the wire out. The outlet will have a strip gauge on the back if the holes are for self holding lugs, and a square or round release next to the hole. You don't have to hit the release when inserting wire,only removing it. If the outlet is rated 120v, 15 or20 amp,it will hold 12ga wire.
Simply put, it is any electrical outlet the has three holes that the female end plugs into. What this is referred to most of the time (but not always) is a regular 110V outlet. Older outlets had only two holes, one for the hot, one for the neutral. All newer installations have the third hole for the ground wire.

The material inside the holes in an electrical outlet is typically brass or another conductive metal. This material is used to make a connection with the prongs on electrical plugs, allowing electricity to flow into the outlet.

The fluid goes inside the air holes/pockets in the soil/sponge/material.
mostly in corners of any place,inside their holes ,or in store room,in waste material
opening, outlet
If you are using proper authorised outlet boxes, they come with all the holes pre-cut. Holes to mount wire clamps and holes for mounting screws. If you don't use these you are not 'to code'
No, but your spit may touch a contact and the shock could kill you. So don't even think about doing such a stupid thing!
Probably, the material covering the mouth is filled with many, tiny holes, allowing the person inside to see out.
That depends on the material and the size of holes. -I can do that on a drill press with a jig.
Spackle or joint compound is the best material to use to fill holes in a wall.
