In the diagram below, what do the three numbered vectors represent?

Explanation:

The right hand rule is used to find the magnetic force acting on a charged particle in the magnetic field. The magnetic force is given by :

Where

I is the current

B is the magnetic field

In this type of rule, the magnetic field, the electric current and the force are mutually perpendicular to each other.

In the given figure,

Vector 1 represent the magnetic field

Vector 2 represents the electric current

Vector 3 represents the force

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.
