Q: A 0.500 g wire is stretched between two points 95.0 cm apart. If the tension in the wire is 600 N, find the wire's first, second, and third harmonics.______Hz (1st)______Hz (2nd)______Hz (3rd): Kia ora In order to answer this question, we first need to ascertain the speed of a wave in this wire. The speed of a wave on a wire depends upon the tension 'T' and the linear density (mass per unit length) 'μ' of the wire. v=√(T/μ) T=600 N The linear density of your wire is 5.00E-4 kg/0.95=5.263E-4 kg/m. So for this wire, v=√(600/5.263E-4) =1068 m/s Now we have the speed, we need to find the wavelengths that correspond to the harmonics we are interested in. The wire is fixed at both ends. Nodes occur at fixed ends. Therefore the first harmonic will occur when there is a node at each end and the longest possible wavelength that satisfies this condition is λ=2L (you get half a wavelength on the wire). So λ=2*0.95=λ=1.90m. If v=1068m/s and λ=1.90 then by the wave equation v=fλ f=v/λ=1068/1.90=562.1 Hz. So that is the first harmonic. The second harmonic has twice the frequency of the first; the third harmonic has three times the frequency of the first. The second harmonic will therefore occur at 562.1*2=1124 Hz and the third at 562.1*3=1686 Hz. Because your data was given to 3sf you need to round your answer to 3sf: 1st harmonic: 562 Hz 2nd harmonic: 1120 Hz 3rd harmonic: 1680 Hz

Q: I am moving a stove that has four wires - bare copper (ground), red, white, and black.The location I am putting it in only has three wires - red, white, and black.Can I just ignore the ground on the new location since it doesn't have one? Or should I cross one of the other wires with the ground?: Your four-wire stove has a terminal where you can connect the bare/green and white wires together, most have a jumper to connect the two terminals. You don't want to leave any wires unconnected. The other two wires (red black) are connected the same way between 3-wire and 4-wire units. You'll have to buy a 3-wire cable for your stove to plug it into the 3-wire receptacle. The new code requires 4-wire connections. The bare/green wire and the white neutral wire are run back to the circuit breaker panel separately at which point the are connected together on a buss bar.

Q: I have a Speedaire 4B234 its currently wire to 120V but keep flipping the breaker and I have a 240V in the garage so I want to wire it to that. I have 2 blue wires, 2 red wire, and 2 green wires but the green wires are hooked together. One blue wire goes to Line and the other to Motor and same thing with the red wires.: Go to any store that sells them and look at the manual. Better still, Google for the manual.

Q: My dog chewed the wiring and i dont know how to re-connect: Lets see, if your dog chewed the wires, he probably did it right at the valves. Here's what you do (depending on how many valves you have) 1. Each valve solenoid has 2 wires coming out of it. Grab one (of the 2- it doesn't matter which) wire from each valve and twist them together. Call this the COMMON wire (usually white). 2. Go to the clock/timer/controller and look to see where the wires are connected. Check to see which color wire is deginated as the COMMON wire (or doesn't have a station number designation) 3. Once you find out which wie is the common, go back to the valves and twist this wire onto your BUNDLE with a wire nut. 4. Connect the remaining wires at each valve to any corresponding wire (on the other end). Make sure that you eventually solidify these connections with waterproof wire connectors. 5. Check the stations at the clock, running individual stations and making sure the correct run-times correspond to the valve assignments- adjust or flip wires at the clock instead of switching wires at the valves.

Q: Does anyone know where i can buy them? I need new ones because my crazy cat chewed up two of the wires lol =#92;: Buy some speaker wire and electrician's tape and splice new wire in the area where the old wire is chewed. Make sure you don't cross positive with negative. This way, you don't have to worry about getting the right connections, and it will be inexpensive.

Q: I understand that in a plug you have the earth wire, live wire and neutral wire. But what is the individual job of these wires?? I know how to wire a plug, i just want to know the individual job of each wire. This is not homework, this is something iam teaching myself.Thanks.: The typical U.S. power distribution system has two hot wires coming into your electric panel, plus a neutral wire. The neutral wire is grounded to earth ground, as is the protective green earth wire. An outlet, carrying 110 volts from one of the hot wires (black), supplies current for the load and it flows back to the transformer on the pole normally via the neutral (white) wire to the center transformer (grounded) tap. The green protective wire does nothing in normal operation. However, should the appliance have a metal outer skin, and the machine develops a short, energizing the outer skin, it will flow through the green ground wire back to the transformer rather than through you and back to the transformer.

Q: what is the best speaker wire for some subwoofers that are rated between 500rms watts to 750rms watts: loxotox has finally conviced me that he is obviously lying about his accomplishments. There is no way in hell that 2 or 4 gauge wire will fit to wire up the coils on these subs. It is physically impossible, unless you shave down the wire. I would not recomend doing that at all, that is speaking from what I know about electronics. I would suggest using 12 or maybe 10 gauge wire. You can use lighter wire but will not get optimum performance from your sub.

Q: Thermostat has two red wires two black wires. The baseboard has one red one black wire.: I'm not sure I understand how you're trying to hook this up. It sounds like you've got two pairs of black and white wires? Were these installed with the intention of supporting a 220 volt device? You really should be seeing a black and a red wire, and measuring 220 volts between them. Try measuring between the two black wires - you'll either get 220 volts, or nothing (if they're on the same leg). What connections are available at the heater, and how are they labeled?

Q: My dad is trying to wire a electric cook top...it has three wires (black, red, and copper). His junction box has four wires (black, red, white and copper). He first wired the black to black, red to red and copper to copper, he capped the white wire in the junction box. The cook top did not work. Then he connected the white wire with the two copper wires, and the cook top now works. So the question is will this connection work or will it cause a problem? And if it causes a problem what can he do to resolve it?: so it is new already == call the 800 number that is with the paperwork and ask the customer service to give you an explanation and email a wiring diagram ... best way to fix and have safety ...

Q: Whenever I'm making jewelry, I typically wind up using crimp beads (with toggle closures, in most cases). Whenever I cut off the beading wire at the end, after enclosing the crimp bead around it, there's always this itsy bitsy part of the wire that irritates me to no end when I wear the jewelry. It seems that I can only cut the wire so much before I wind up snipping at the crimp bead. How can I remedy the irritation fact of the left-over wire?Maybe put glue on the wire piece and let it dry? Idk. Grr.: Depending on the size of the hole in the beads, I usually run the wire down throw about 2 inches worth of beads; then crimp and clip. This also ensures that if the necklace if caught and pulled you have about 2 inches of slack before you are chasing beads on the floor. If you hole in the beads are small you can do two different things. 1) find a coordinating bead with larger holes that you can end the necklace with on both sides of the catch 2) Be sure your wire is running straight back down the original wire after going through the crimp, then crimp and clip.The end of the wire will be straighter and not tend to go out to the side and punch your neck. And unfortunately there is not a solution every time.
