a parallel-plate capacitor has capacitance c = 12.5 pf when the volume between the plates is filled with air. the plates are circular, with radius 3.00 cm. the capacitor is connected to a battery and a charge of magnitude 25.0 pc goes onto each plate. with the capacitor still connected to the battery, a slab of dielectric is inserted between the plates, completely filling the space between the plates. after the dielectric has been inserted the charge on each plate has magnitude 45.0 pc.

The smokey mountains have over 2,100 miles of rushing mountain streams and rivers that flow through the park. in each mile lives a diverse community of native fish, amphibians, insects, and larvae, some of which are found only in the southern appalachians. park managers and scientific researchers test many factors such as fish populations, the watersheds and water tests to determine a) too many lizards are present b) the water quality of the stream c) rainwater is running into local streams d) if visitors to the park are overstaying their welcome
