The resistance and the magnitude of the current depend on the path that the current takes. the drawing shows three situations in which the current takes different paths through a piece of material. each of the rectangular pieces is made from a material whose resistivity is rho = 1.50 x 10-2 ω*m, and the unit of length in the drawing is l0 = 7 cm. each piece of material is connected to a 3.00-v battery. find (a) the resistance and (b) the current in each case.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
