Question:

Physics Help!!!! A copper pipe has an inside diameter of .?

A copper pipe has an inside diameter of 3.00cm and an outside diameter of 5.00cm. What is the resistance of 10.0m of this pipe?copper‘s resistivity 1.72 x 10^-8I can‘t seem to solve this problem. I‘ve tried to do the RpL/A for both the diameter inside and outside then subtract it, but it still isn‘t the correct answer. Please help me with this! Thank you! 10 pts for the best answer!!!!

Answer:

R 4Lρ/[π(Do? - Di?)] 4*10*1.72E-8/[π(.05? - .03?)] 0.0001369 Ω The diameters have to be in meters
no usually it uses the same oil as the the engine. Except for a 2 stroke, which has oil in the transmission. Automotive oil will break down faster in a motorcycle, because it goes through the trans. That why they make motorcycle oil. I feel synthetic cures that issue. Have used mobile one in my bike for years

Most 4 stroke bikes have engine oil, primary oil and transmission oil. Some companies claim that they make one oil that will work in all three areas of the bike because all of the oils share the same base material. oil. Each oil needs its own blend of additives to give it the proper properties it needs to function in each compartment. A single oil will work well in one area but may suffer in others. One would have to damn near be a lubricants scientist to be able to give an honest answer to the differences. But they are different. It is usually best to use an oil in its own respective spot.
