Explain why the current is reduced as electrons move through a conductor.

The current is reduced as less energy is available to move electrons through the wire.

This is because electrons moving through the conducting substance collide with the electrons and ions.

This causes collisions which further more convert kinetic energy into thermal energy because of the fewer energy that is available, it reduces.

Moreover the resistivity factor of the conductor it self might play some role and the loss of energy too.

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.
