Hard wired means that there is no plug and receptacle in the circuit powering the dryer. What you will find is a metal jacketed cable that will come out of the wall or floor and go right into the dryer.
House wires are made of copper. They're jacketed in plastic or rubber to keep from setting flammables on fire, to keep short circuits from happening and to keep things from being electrocuted.
When a 3 prong electrical outlet tester indicates an open ground, it is telling you that the d shaped slot on the outlet is: not connected to the ground conductor ( the bare or green jacketed wire that is supposed to provide an electrical connection to the earth) or that if it is connected to the designated ground wire the wire itself is not connected to the earth or perhaps there is no ground conductor available in the electrical device box where the outlet is located. Many areas of the country did not require that a ground conductor had to accompany the hot and neutral conductors in electrical devise boxes until somewhere around 1960 or so and some areas didn't adopt that requirement until several years after that. If there is no ground wire in your devise box you are out of luck and you should install an old style 2 prong outlet to prevent use of appliances that require a ground or you should run modern wiring to the location. If you are asking this question it means that you don't have a basic understanding of electrical wiring. It would be prudent to consult someone who has that knowledge to assess and guide you before you attempt to correct the situation.
If you are asking about the only two nuclear bombs used against a nation in world war two, I will answer it. The nuclear bomb used in Hiroshima was an uranium bomb. The second one used in Nagasaki was a plutonium bomb.Radium could have been used in the neutron source, but is far too expensive and gives off too much Beta & Gamma radiation which could have damaged the bomb. Polonium was used in the neutron source instead.
When you heat glass enough to almost melt it, it becomes a gooey, gluey substance, like very stiff slime. In that condition, it's rolled flat to make window-glass, or spun on the end of a rod to make cups and bottles, or blown up like a balloon to make bottles with very thin necks. Also when glass is in that condition, if you grab a little pinch of it (with tongs!) and slowly pull it away from the main glob, it stretches way out and becomes very thin before it finally breaks. It can be stretched to where it almost has the consistency of cotton candy or fine hair, and that's the material used in fiberglass home insulation. When it's stretched not quite as thin as that, to the thickness of a thick sewing thread or a nylon fishing line, it's quite flexible, and in this condition, a plastic jacket is formed over it, just like a piece of wire, then several of them are jacketed into a single cable and used for "fiberoptic" data communication ... a pulsed bright infrared light, injected into one end with a laser diode, travels very nicely through several miles of this glass thread to be received at the other end of the cable. So "fiberglass" is glass that's been melted and stretched until it's no thicker than all those other things we've been calling "fiber" for hundreds of years.
The inner pipe of jacketed pipeline is normally referred as CORE pipe.
That depends if hollow point or jacketed and what size engine block.That depends if hollow point or jacketed and what size engine block.
Basically, jacketed, semi-jacketed, lead, in the following types: round nose, wadcutter, semi-wadcutter, hollow point, flat base, boat tail. as well as high velocity and soft points, as well as copper tipped HV rounds.
Every manufacturer has their own special designs, but generally there are jacketed hollow points and unjacketted hollow points.
Reduces barrel fouling
Jacketed Hollow Point
2 peice of foam & use to sandwich multiple different size cables ? jacketed cable PUE/PVC MATERIAL .
For most uses, a jacketed hollowpoint.
No. Plated is not the same thickness as plated.
There are about a dozen different "38s" other than the .38 Special. In the .38 Special caliber, there are round nosed lead, jacketed soft point, semi-wadcutter, wadcutter, jacketed hollow point, full metal jacketed, tracer, shot loads, metal piercing and multi-ball buckshot loads. Besides the .38 Special, there is .38 S&W, 38 Short Colt, .38 Enfield, .38 Long, .38 Remington, .38 Corto, .38 Super, .38 Auto, .38 AMU- and probably several others in my references. You can make a large cartridge collection just from the varieties of 38s.
Ammuntion that has a thin jacket of metal (copper for example) that encloses the lead projectile.
Total Metal Jacketed Flat Point. Many "jacketed" bullets have some lead exposed- usually at the base. TMJ wraps all of the bullet in jacketing metal. This can reduce leading of barrels, and airborne lead (indoor shooting ranges)
