Consider the situation of solute in all tration. let us denote by car, t), the tion of solute in a thin pipe of length l is transfer due to differences in concen- s denote by c(x, t), the concentration at x at time t and let (c. t) be the flux (mass per second) at r at time t. use the law of conservation to derive the diffusion equation for c, in the solute is pumped in the pipe at a rate of f (x, t).

answer; i believe the correct answer is (40,000 j) good luck

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.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
