A power source supplies an electric potential difference of 9.0 V to the plates of a capacitor. The energy stored in the capacitor is 9.8 x 10 4 J. The dielectric constant of the dielectric in the capacitor is 5.1. the radio of the area of the plates to the distance between the plates, rounded to two significant figures is × 10 power 5 m.​

Uppose we consider the system of the three capacitors as a single "equivalent" capacitor. given the charges of the three individual capacitors calculated in the previous part, find the total charge qtot for this equivalent capacitor. express your answer in terms of v and c.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
