Uniform circular motion describes the motion of a body traversing a circular path at constant speed. Since the body describes circular motion, its distance
from the axis of rotation remains constant at all times. Though the body's
speed is constant, its velocity is not constant.
(1) What is the distance travelled by the object if it goes a complete round in a
circular path of radius 50m?
(II) What is the displacement in the above situation?
(iii) Calculate the speed of the object if it takes 20sec to complete a round.
(iv) Calculate the average speed after completing 3 rounds.
PLEASE HELP

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.

i think the answer would be b

thermal energy is the answer

answer is slate

hope this
