You are on an aluminum ladder that is standing on the ground, trying to fix an electrical connection with a metal screwdriver having a metal handle. Your body is wet because you are sweating from the exertion; therefore, it has a resistance of 1.9 kΩ . Neglect the resistance of the ladder and the ladder-ground contact.

- Plethysmographs are devices used for measuring changes in the volume of internal organs or limbs. In one form of this device, a rubber capillary tube with an inside diameter of 1.00 mm is filled with mercury at 20.0°C. The resistance of the mercury is measured with the aid of electrodes sealed into the ends of the tube. If 100 cm of the tube is wound in a helix around a patient’s upper arm, the blood flow during a heartbeat causes the arm to expand, stretching the length of the tube by 0.040 0 cm. From this observation and assuming cylindrical symmetry, you can find the change in volume of the arm, which gives an indication of blood flow. Taking the resistivity of mercury to be 9.58 x 10-7 Ω ⋅ m, calculate (a) the resistance of the mercury and (b) the fractional change in resistance during the heartbeat. Hint: The fraction by which the cross-sectional area of the mercury column decreases is the fraction by which the length increases because the volume of mercury is constant.arrow_forwardA student finds two ancient meters with numbered scales but no unit markings.

He can conclude that Group of answer choices A is the voltmeter and B is the ammeter. neither can be a useful meter. B is the voltmeter but A cannot be a useful meter. A is the voltmeter but B cannot be a useful meter. B is the voltmeter and A is the ammeter.arrow_forwardYou’ve made the finals of the Science Olympics!
