Aconductor is placed in a steady external electric field. which of the following statements are correct for this situation? (there could be more than one correct choice.) check all that apply. check all that apply. none of the above statements are correct. all the free electrons go to the surface of the conductor. the electric field is zero inside the conductor. the surface of the conductor is neutral. the electric field just outside the surface of the conductor is perpendicular to the surface.

All the free electrons go to the surface of conductor

Electric field is zero inside the conductor

Electric field is perpendicular the to the surface of conductor just outside the conductor

Explanation:

There is property of conductor that all the charges flows towards the surface of conductor and there is no charge inside the conductor

If there is no charge inside the conductor then electric field will also be zero because electric filed is produced due to charge

If there is no charge then there will be no electric field

The field just outside the surface of conductor is normal to the surface of the conductor so field will be perpendicular to the surface

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.
