Not to mention time too. When your friend needs you, sometimes when things are not going too well on your side, it is often so easy to turn a deaf ear to their pleas(请求). It is especially during these times, that you must find the strength in you to help your friend. And it ...
The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needl...
The metal copper has a specific heat of 0.386 J/g⋅K. How much heat is needed to raise the temperature of 1 kg (1,000 g, or 2.2 pounds) of copper from 0 °C to 100 °C? Q = (m)(C)(ΔT) = (1,000 g)(0.386 J/g⋅K)(100 K) = 38,600 J = 38.6 kJ. ...
independent rating system in place. You might have noticed the “80 Plus” rating on many power supplies, often listed alongside a precious metal. To receive this rating, a power supply must be at least 80 percent efficient, meaning that a maximum of 20 percent of power is lost as heat....
Motherboards group external ports on their back panel, which is covered with a removable or integrated “I/O shield” that is grounded due to its contact with an often metal case. This is sometimes attached to the motherboard, or comes separately to be installed when putting together the sys...
These weapons hurl projectiles at a high rate of speed, giving them enough energy to penetrate thin layers of metal. You can increase the thickness of traditional armor materials, but they soon become too cumbersome and heavy for a person to wear. It wasn't until the 1960s that ...
