Resistivity and conductivity are reciprocals : . Resistivity is a measure of the material's ability to oppose electric current. This formula is not exact: It assumes the current density is totally uniform in the conductor, which is not always true in practical situations.
All depends on how fast they pedal and what kind of a bike they're on. When I ride with my family ... about 10 mph When I ride solo on my road bike ... about 17 mph In todaâ¦y's stage of the Tour de France, the average rider was expected to (during the last 26 km) average about 80kmh, or 49+ mph. Depends on how you categorize riding.
How fast is a 125cc dirt bike? 90 to 95 mph but depends on the size I have had various high quality street legal dirt bikes over the years, they tell me the ones today have velocity limiters of some type â¦ now, I do not know anything about them, or if it is true or not, I really don't care one way or another anyway.ut it really depends on who makes it. Some 125 cc 2 stroke race mopeds will do 70+mph, while some cheap 125cc 4 str â¦ oke import mopeds will barley do 52 mph. 2 people found this useful. Svelia.
