- 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: OK - I removed my old light switch and can see that there are only 2 wires coming out of the wall to be found - 1 white and 1 black. There are absolutely no other wires that I can see back there. The dimmer switch has 2 black wires and 1 green. I'm really not sure what to do. I tried to connect the 2 black ones to the black one and the green wire to the white wire. I admit this wasn't the smartest thing, but thought I'd try. Got nothing. Any help is super appreciated.
- If the 2 wires you refer to ( 1 black 1 white) were connected to the switch you took out , then attach 1 black wire from the dimmer to the black wire in the box and 1 black wire from the dimmer to the white wire in the box. The green wire is always ground and should be attached to either the metal box or if it is a plastic box to the bare wires in the box. If you just have those 2 wires in the electrical box it is known as a switch loop. If it is wired properly the power is coming in on the white wire. and when it is switched to the black wire it sends power to your light. Make your connections using wire nuts. No tape is necessary when it is done correctly. Tape is only used to insulate. Good luck.
- Q: I keep thinking that the wire would cut into the bark when the bonsai is growing.I want to wire it now because it is easily manipulative, but I don't want to prevent trunk growth
- Wire it, let it grow a bit. Then, as necessary, undo the wire, then rewire it to fit the new size. An alternative is to append weights, or tie strings to other objects or parts of the plant instead of wiring a whole branch.
- Q: So Ive never done wiring for my car, But my friends are willing to talk me through it. But the next time I can talk to them is next week and they kept telling me to tap into wires. but What does that mean? like, what does it mean to quot;tapinto the wires?
- Tap means to splice into a wire. To join a new wire to the middle of an existing wire. Such as joining the wire for your new driving lights to the existing wire for the normal headlights. Before getting scared about cutting and soldering. Go to the parts store and get some IDCs. Just ask the counter guy for some suitcase connectors. You lay two wires next to each other and fold the IDC over them. When you squeeze it with pliers, it will join the two wires together.
- Q: i got this switch with numbers 1 , 2, 3, and 4 on it and 4 wires red, green, and two black. Which wires go to which number?
- Well it is defintely a 3 way switch. The fourth (green) wire being the ground. I can't tell you by the numbers, but I can tell you by the screws which wire goes where. If it does not apply to your switch you may need to go get a new one. They are inexpensive. The green, ground wire goes to the screw that is usually attached to the arms ( metal extentions that hold against the sheet rock. Now you need to find the red and black wire that are together. Look inside the box where the wires come in and you should be able to tell if the red and black are in the same sheathing. These are your travelers. The travelers need to go on the two screws that are across from eachother. One goes on the right side and one goes on the left. Does not matter which side. The last black wire, depending on which of the two 3 ways you are at is either your power or your light leg (wire going to your light). This wire goes on the last screw. Hope this was helpful.
- Q: How much wire is required?
- Length of wire is L = R*A/p SI units must be used, so convert radius to meters: r = 0.0254 / 64 m using 25.4mm = 1 inch r = 3.969*10^-4 m (0.3969mm) So cross-sectional area is A = pi*(3.969*10^-4)^2 m^2 A = 4.95*10^-7 m^2 The average resistivity of nichrome is p = 1.1*10^-6 ohm-meter So the required length of wire is L = 2.2 ohm * 4.95*10^-7 m^2 / 1.1*10^-6 ohm-meter L = 0.990 m
- Q: If you hang a pot-plant with mass of 8kg from two lengths of wire attached to a horizontal beam 100cm apart. The wire on the left has a length of 50cm and the wire on the right has a length of 75cm.What is the tension in both wires?
- The tension in both wires.? If you hang a pot-plant with mass of 8kg from two lengths of wire attached to a horizontal beam 100cm apart. The wire on the left has a length of 50cm and the wire on the right has a length of 75cm. What is the tension in both wires? In the triangle ABC, AB(c) = 100 cm, BC (a) = 50 cm and AC (b) = 75 cm 2s = a+b+c = 225 cm s = 112.5 s-a = 112.5 - 50 = 62.5 s-b = 112.5 - 75 = 37.5 s-c = 112.5 - 100 = 12.5 tan A/2 = √ {(s-b)*(s-c) / [s*(s-a)] = √ {37.5*12.5) / [112.5*62.5] A = 28.95? tan B/2 = √ {(s-c)*(s-a) / [s*(s-b)] = √ {12.5*62.5) / [112.5*37.5] B = 46.57? C = 180-28.95-46.57 =104.48? --------------------------------------... 46.57? is the angle between horizontal and 50 cm wire. 28.95 is he angle between horizontal and 100 cm P is the tension in the 50 cm wire and Q is the tension in the 75 cm wire Equating the horizontal components of the tensions P cos 46.57? = Q cos 28.95 ? P = Q cos 28.95 ?/ cos 46.57? P = 1.27 Q-------------------1 Equating the sum of the vertical components of the tensions to the weight of the pot P sin 46.57? + Q sin 28.95 = 8*9.8 N 0.73P + 0.48 Q = 78.4N 0.73(1.27 Q) + 0.48 Q = 78.4N Q = 55.72 N and P = 70.76 N ============================= Or use Lamis theorm Angle between P and Q = 104.48? Angle between P and the pot = 90 + 46.57? Angle between Q and the pot = 90 + 28.95 By Lamis theorm P/ cos 46.57? = 78.4/ sin 104.48? P = 55.67 N and Q = (78.4/ sin 104.48? ) cos28.95 = 70.85N ====================================
- Q: The light fitting I bought has 1x Red Wire (A) 1x Green Wire (E) and 1x Blue Wire (N)...
- The green wire is just a ground wire, black is usually the hot wire, that would leave the blue wire as the neutral wire. The white wire in house wiring is the neutral. The two red and one black from your wall is not standard in the USA, but it may be 220 volts. What kind of light fixture are you replacing, is it on a ceiling fan?
- Q: what is the best wire to use for a chainmail
- Costume or 'Historically Correct'? You can buy soft iron or aluminum wire in any gauge you can 'knit'. ( 14 is about right for Al., 16 for iron.)
- Q: like can u use home power wire that is 4 gauge rather then getting the car power wire
- Home okorder /... (spanky, well trying to run solid wire in a car would be a real task! lol) And, 4 gauge can handle more than 95 amps.
