Problem 3 A potential difference is set between the ends of a 10 cm long tissue Fat tissue sample that can be modeled as a fat resistor and a muscle resistor attached together as in the picture, both 10 cm long. The cross-sectional area of the fat tissue is 2 x 10-$ m while that of Muscle tissue the muscle tissue is 3 x 10-m-. Separately each piece by itself has a resistance of Rmuscle = 430 2 and Rfat = 1250 02. (a) [2 points] Determine the resistivity of the fat tissue. (b) [3 points] Determine the resistance of the tissue sample. Problem 4 A capacitor consists of two parallel plates, each with an area of 2 m , separated by 0.3 mm. (a) [3 points] Calculate the amount of charge stored on each plate when the capacitor is connected to a 5000 V battery
