Apoint charge with charge q1 is held stationary at the origin. a second point charge with charge q2 moves from the point (x1, 0) to the point (x2, y2). use k for coulomb's constant rather than writing it out as (1/4πϵ0).how much work w is done by the electrostatic force on the moving point charge? express your answer in joules. use k for coulomb's constant.

the answer would be c. motion and direction

i hope this : )

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

false

explanation:

boats, things on boats luggage are way more heavy then water.

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.
