The soil contains wetlands with decomposer who release methane (CH4), a greenhouse gas that is 25x as powerful as CO2 . As the Arctic thaws, these bacteria become active again. Describe how this process could also become a climate feedback loop.

Adielectric-filled parallel-plate capacitor has plate area a = 30.0 cm2 , plate separation d = 9.00 mm and dielectric constant k = 3.00. the capacitor is connected to a battery that creates a constant voltage v = 15.0 v . throughout the problem, use ϵ0 = 8.85x10-12 c2/n. m2 . find the energy u1 of the dielectric-filled capacitor.
