A15.0-v battery is connected to terminals a and b in fig- ure 21–41. (a) given that c = 15.0 mf, find the charge on each of the capacitors. (b) find the total energy stored in this system. (c) if the 7.22-mf capacitor is increased in value, will the total en- ergy stored in the circuit increase or decrease? explain.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
