Question 1 This question contains multiple parts. Make sure to read all the instructions and answer each part. Image size: s ML Mi Two air-filled parallel-plate capacitors with capacitances C, = 4 uF and C2 = 6 uF are connected in parallel to a battery that has a voltage of 36 V. (a) What is the total positive charge stored in the two capacitors ? (b) While the capacitors remain connected to the battery, a dielectric with dielectric constant 5 is inserted between the plates of capacitor C1, completely filling the space between them. Then what is the total positive charge stored on the two capacitors? Does the insertion of the dielectric cause the total energy stored to increase or decrease ? Part a (1 points What is the total positive charge stored in two capacitors? Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8 0.00036 C Part b (1 points) What is the total positive charge after inserting the dielectric material? Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8 0.000936 CV No answer submitted Part c (1 points) Does the energy stored in the two capacitors increase, decrease, or remain the same? 94.8% Increase 1.7% Decrease 1.2% Remain the same Question 2 What is the resistivity (of the material that make up of the rod)? Image size: A 1.5m cylindrical rod of diameter 0.5cm is connected to a power supply that maintains a constant potential difference of 15V across its ends, while an ammeter measures the current through it. You observe that the ammeter reads 18.5A. Find the resistivity. Please enter a numerical answer below.
