Shareen performs a skit to model a method of charging. in the skit, a painter shakes her hand and gets paint on her.

how does the skit model a method of charging?

it models induction because the painter represents a neutral object and the paint represents electrons that are transferred through rubbing.
it models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
it models induction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
it models conduction because the painter represents a neutral object and the paint represents electrons that are transferred through rubbing.

It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.

Explanation:

Conduction phenomenon of charging is the process of charging in which two bodies are made in contact with each other so that charges are transferred due to potential difference of two bodies.

here we know that when hands are shake then it will have paint on it. so here due to hand shake the hands are in contact with charge particles and due to contact the electrons are transferred to the hand.

Now here we need to assume that charge of paint must be opposite that of the charge on the hand because only due to opposite charge attraction the paint must be transferred to the hand

SO here correct answer will be

It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

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.
