Pllsss which of the following is a force acting between objects that do not touch? normal force
frictional force electrical force applied force

Electrical force

Explanation:

Of the options given, the electric force is the only force that acts at a distance, that is, it is not necessary for two objects to be in physical contact for there to be electric force between them (Another example of force acting at a distance is the force of gravity.).

Instead, forces such as the normal force, friction force, and applied force all need contact between objects to take effect.

For example if an object does not touch the surface the normal force is null.

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.
