The resistance of physiological tissues is quite variable. the resistance of the internal tissues of humans, primarily composed of salty solutions, is quite low. here the resistance between two internal points in the body is on the order of 100 ohms. dry skin, however, can have a very high resistance, with values ranging from thousands to hundreds of thousands of ohms. however, if skin is wet, it is far more conductive, and so even contact with small voltages can create large, dangerous currents though a human body. (for example, although there is no specific minimum current that is lethal, currents generally exceeding a couple tenths of amps may be deadly.) assuming that electrocution can be prevented if currents are kept below 0.15 a, and assuming the resistance of dry skin is 100,000 ohms, what is the maximum voltage with which a person could come into contact while avoiding electrocution?

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
