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.
I know a bunch of cyclists...they do an average of 30 miles on their daily rides. I usually ride for time, not mileage. A short ride for me is maybe 1 1/2 hours. A long ride is at least 4-6. I do a couple of short rides per week, two mid-range (2-3 hours) and a least one long.
