Q:Does throwing punches with weighted cables increase punching power?

Not necessarily because punching power is basically genetic or in-born. It will help for sure but it's not an assurance of you acquiring instant knockout power.

Q:I need a cable to connect my SATA hard drive to my computer's motherboard (which already has the SATA ports). Is this the correct cable:

Yes that is the correct cable that plugs into the motherboard SATA ports. Regarding the power cable. Some SATA drives have both the old style 4-pin power connector (like on the IDE drives) as well as the newer SATA power cable. If it has both, DO NOT plug both in at the same time or it can damage your PC. You can use one or the other but not both.

Q:a usb cable has 5 volts and 2.5 watts. so can it still power if it has 5 volts and 1.5 watts

Uh...YES! The voltage matches and the current will be regulated by the resistance of the device being powered. It will work fine.

Q:I cant find the power cable for this CRT monitor I have, But I have this power cable from an LCD monitor. Would it work if I put the LCD monitor power cable in the CRT monitor? Will it fry the CRT if I try?

No. It should work.

Q:How can you tell which lines on telephone poles are power lines, cable lines, and phone lines?

The higher they are up, the Higher the voltage. Of course, high voltage power will usually have individual bare aluminum conductors on porcelain or plastic insulators. Lower voltage (120/240 in North Amercia) is either three or four conductors on a set individual insulators, or two or three insulated wires wrapped around an aluminum wire (steel cored actually). The 4th wire, if there, is for street lights. Telephone is a think cable, with junction boxes evert few homes, which the customer lines come off of. Cable lines are a round coax, which connect to its pole equipment with threaded connections, usually with hex fittings, and splitter/taps which customer lines conenct to. Cable lines also have power injector boxes every often. They supply the power for amplifiers. If the wires are overhead to a home, you can usually tell by what they connect to. Electricity is obvious, the individual conductors from the lateral connect to the individual conductors on the drop, which lead to the meter. Telephone and cable both usually go to similar boxes on the house, but cable continues with one or more of similar coax, while telephone goes in with a JKT, Cat 3, or 5 cable, often grey.

Q:The computer is a Hp compaq.So I took the connector out of the computer but left it in the power socket.When I tried to reinsert the connector I hit the metal back panel of the computer and it made contact so I was wondering what is the part(s) that is likely to be broken?I want to know it so I can replace the damaged parts.Thanks in advance of your help.

...might want to be check that you didn't trip the house breaker for that outlet. As in plug something else into it and see if it gets power....

Q:I have an old scanner, HP Scanjet 3400C, but I have lost the power supply cable. The power socket the cable fits into looks like a small single hole with a little pin in the middle.Can I replace it and what is it called?Thank you very much.

The power cable and adapter will probably be unique to the scanner. You'll have to order the right one from HP, or through a computer store. The USB cable should be standard. Most printers and scanners use a USB cable with a Type A connector (flat) on one end, and a Type B connector (squared-off) on the other end. They're easy to find at Staples, as well as at computer stores.

Q:I have a yamaha dgx-300 keyboard, and lost the power cable to it about a year ago. Do any stores like circuit city or something carry a power cord that would be compatible with my keyboard?

what type of power cord does it use? if its a regular ac input, you could just use any ac plug with the correct amount of power <-- this isn't the recommended choice, just a posibility.

Q:I managed to break off the tip of my laptop power cable to the point that I need it replaced. I can't pay with cash on OKorder and don't own a credit card. Anyone know an electronics store where I could find another? Thank you.

You okorder /

Q:Hi, just moved to Finland from US. Will my x box 360 works with a new powell cable? Or do I need something else besides that. And where should I get it from in Turku or Helsinki. Thank you!

You could probably buy an adapter plug for your existing cable. Getting a whole new cable might very well mess with the machine itself, and be more expensive than a simple adapter. Just go to an electronics’ store, with the cable, (the bigger the better) and ask for a suitable adapter for it.
