Aperson will feel a shock when a current of greater than approximately 100 μa flows between his index finger and thumb. if the resistance of dry skin is 200 times larger than the resistance of wet skin, how do the maximum voltages without shock compare in each scenario? a the voltage on dry skin needs to be 200 times smaller than the voltage on wet skin. b the voltage on dry skin needs to be 200 times larger than the voltage on wet skin. c the voltage on dry skin is the same as the voltage on wet skin. d the voltage on dry skin needs to be 40,000 times larger than the voltage on wet skin.

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
