(15 pts) o move in a spiral orbit given by the equation r aθ2 a particle of mass m is observed t where a is a positive constant. a) is it possible to have such an orbit in central force ? . if so, determine the form of the force function, f(r). b) how the angle θ(t) varies with tirne. note: the differential equation of the orbit for a central force is 瓜(t )

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

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.

this could be newton#'s law of cooling. the cooling curve is exponential
