Cryogenic vacuum pump works by condensing vapors onto some absorbent medium. this is an efficient and clean way to pump a system in a research environment. the term cryo means cold, which indicates that these types of vacuum pumps contain a refrigerant cycle to cool the internal parts. the temperature difference between the inside and outside of a typical cryogenic pump is δ t = 300 ∘ c . derive an expression to convert this difference into fahrenheit and express the answer.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
