Q:My friend is buying under-wired bras and what are they and the heavily- wired bra?

The under wire is a stiff piece of plastic, wire or some other kinds of material, that is sewn into the bottom of the cup for added support. If you are not really busty or sagging, you don't need them. They are also pretty uncomfortable because the under wire always seems to push directly onto a rib.

Q:im installing a JVC raido in my 1990 nissan maxima and cant figure out how to properly conect the wires

The easiest way to install the head unit is to buy the harness adapter that's for your car and match the colors of the harness adapter to the head unit wiring harness. An antenna adapter will also be needed for the new head unit. A dash kit will obvious will be needed to make the installation seamless.

Q:I accidently spilled soda all over a bunch of wires and controllers. I cleaned the controllers off and they're not sticky, but what should i do about the wires?

Stick them in uncooked rice overnight along with any other wet electronics such as cellphones, etc. Make sure you use enough rice to completely cover the item. It will absorb any moisture. Do not eat the rice afterward.

Q:How can I investigate the resistance of wire and how it changes with the length of the wireCheers

If you don't have a multimeter, you can probably see the effect of resistance with a flashlight bulb and a small battery (AA or AAA, etc). Get a spool of wire, needs to be coated/insulated wire. Connect the bulb to the battery with the shortest wire possible. See how bright the bulb is. Then, connect again using the entire spool of wire (hopefully you can get at both ends of the wire while it is still on the spool). The bulb will be dimmer because the voltage at the bulb will be reduced by the resistance of the wire (resistivity per unit length X the length of wire). If the length of wire on the spool is too long, the bulb will not light up at all.

Q:14. Three parallel wires carry currents, with magnitudes and in the directions shown in the figure below. The wires all lie in a plane, and are all 2 m long, with separations between them as shown in the figure. What is the total force on wire #3 due to wire #1 and wire #2? Wire 1 : 6A, 2.5 m from Wire 3 ---------------------gt;Wire 2: 3A, 1.0 m from Wire 3 lt;--------------------Wire 3: 3A ---------------------gt;Can't figure it out, any hints/suggestions?

The formula for force between wires is: (?/2π)(current1)(current2)(length/r) ? = 4πE-7 Tm/A r=distance between wires For this problem, you would just find the force on wire 3 of each one separately. Since wire 2 is going opposite direction as wire 3, they repel each other, while wire 1 and wire 3 attract each other since they are going same direction. I get Fwire1 to be 2.88E-6 N, and Fwire2 to be 3.6E-6N. Then subtract them since opposite forces, and since Fwire2 is stronger, the force would be 7.2E-7 N away/repelling.

Q:I have two low voltage wires that run from one side of a building to another. The insulation on both wires is the same color. I eventually just walked an additional wire around the building and checked continuity. Is there an easier way to differentiate between the two wires?

i think i get what your saying if for example your running 3 black wires (the insulation is black)and each one is for example a line or hot wire i would take different colored tape and color code each one on each end it eliminates having to ring them out RING =continuity

Q:I dont' know if quot;a wiremeans phone call, or whatever the original sentene from the story is as follows:quot;Because I had a wire from Hilton Cubittthis morning.quot;

Wire is as obsolete a word as telegram or cable, which is what wire stands for.

Q:Im currently running 8 gauge power wire from my battery to my amp which is a hifonics zxi8408 i have it bridged to 2 channels so its pushing 440 watts x2 to 2 alpine type Rs. The current speaker wire im running is 16 gauge.My question is...since im going to go down to 4 gauge power wire, should I lower the speaker wire and get 12 gauge speaker wire also? What will sound the best?

Actually YES, the speaker wire should always be twelve gauge especially if you want crystal-clear sound. And you SHOULD get 4 gauge power and ground wires as well. They sell great quality audio cables at Walmart.

Q:Is there really a difference between audio wire and regular house wire? If you say yes then please explain, in understandable scientific terms why, or point me to a site that can.

Yes there is a difference because a amp needs a certian amount of amps to work. You can use any kind of wire, hell u can even use a coat hanger, what happens when you use the worng guage wire is you put a strain on the device. That is why amps run hot, or pop fuses, and you wont get the full potential of the amp, shorten its life etc.

Q:I removed the thermostat before marking the wires and I need to know if anyone knows which wires go where?

Hello Kaitlin: It depends on what wires come from the furnace. You will need to go to the furnace and look at the wires. If it is a gas furnace (with air cond.), there should be a R terminal with a red wire attached this is the power line. The W terminal (heat) has a white wire attached. The G terminal (fan) should have a green wire. The C (common) terminal may have a blue or black wire (or not). The Y (cooling) terminal may have a yellow wire. If it is a heat pump, the wires will be R (power), Y (compressor), O or B (reversing valve), G (fan), C (common), the backup heat has different designations, from W2 to Aux, others. There should be a legend on the furnace to assist. Good luck.
