I understand that in nature wind would never get high enough, but I am just curious as to whether physics would allow this to occur or not.

Expert Solution

I think that some confusion is here. Wind speed is determined by differences in the air pression between two points. The max. limits that we observe must set the max wind speed. Wind is the movement of a mass of air. The Sound speed determines the sound barrier. Sound speed is determined by considerations about density, temperature... and is a property about the relative speed of the wavefront of a sound event (a perturbation of te medium - air, that propagates) in relation to te the air (considered at rest). The speed of sound in relation to the ground is the vector addition/subtraction of the sound speed (+-340m/s) with the speed of wind in relation to the ground. The max wind speed is observed in the jet streams in altitude and in the tornados and hurricanes at surface. Somewhere we can find the max speed of the exhausted air in the jets and determine if air moves trhu the air with a speed superior to the speed barrier. Nothing prevent this from happening with enough thrust. I've no time to search now, sorry.

EDIT add:
There is is need to search. The exhausted mixture of jet engines, not beeing wind but mostly a mass of air, can travel thru the atmosphere at speeds much superior of sound barrier. If it is was no so the jet planes could not cross the sound barrier.
So, inspite of the confusion in the question, I the short answer is a Yes (a mass of air can travel faster than max sound speed).

i am doing an internship in the physics department i was lucky enough to actually get this internship as ive just finished my first year. the problem is i have a very professional professor he is so so smart so whenever he explains something to me i just don't understand it, i feel like we have so much mis understanding between me and him. The way he asks me to do things seems so vague to me but so obvious...

I understand the answer to this I am just having a hard time creating a graph for it. Bill the butcher is upset because the government plans to tax beef $.10 a pound. "I hate paying taxes," he says. "Because of this, I'm raising all my beef prices by $.10 a pound. The consumers will bear this burden, not me." Do you see anything wrong with this way of thinking? Explain. Draw a graph describing your answer and attach it...

How would I get rid of punctuation that's in a file so that I am only left with words after turning them into a list in Python. So if the file contained "and in the dream, I am flying.", how would I get a list that contained ['and', 'in', 'that', 'dream', 'I', 'am', 'flying'] not ['and', 'in', 'that', 'dream,', 'I', 'am', 'flying.']

I am curious if there is a preference for Star Wars, Battlestar Galactica, Doctor Who, or Firefly among students at Pierce College. I ask 300 students to choose which they prefer. Below are the results. Conduct a χ² square to determine if there is a preference. Use an alpha (Type 1 error rate) = .05.
