Homework Statement Homework Equations First Law, U = Q-W We also need to apply a force equillibrium on the pistons The Attempt at a Solution Since the problem says the walls and pistons are insulated, we know there is no heat transfer and the process is adiabatic but not...

In my experience, professors are always more than happy to answers my questions during office hours, as long as they are not questions that I could have figured on my own by spending a little extra time on the material I'm studying.

Whats are some of the math courses (or topics) that you take in Mechanical Engineering programs, or any other engineering programs?

The problem with your solution is that a is not constant when the chimney is falling. You have to use mgh = .5mv^2 to find v and then you can find a tangential. To find the change in height, you must use the center of mass of the chimney ( the middle) when it is straight, and when it it at an...

I know that the equivalent capacitance for two capacitors in parallel is C1+C2=Ceq. But consider I charge 2 plate capacitors so that each capacitor has a positive and negative plate and then I connect the positive plate of one cap. to the negative plate of the other capacitor in a parallel...

In case you are still wondering what those course codes mean, they are cegep courses(quebec pre-universitary program). I am currently taking them. These are the courses... General biology general chemistry, chemistry of solutions, calculus 1-2 and elementary linear algebra physics:mechanics...

I meant a linear function y=ax+b with the slope a as infinity, but I guess you already answered the question.

If we simply differentiate the equation, we get infinity as the derivative. However if we were to graph the equation, any x < 0, gives us y= infinity. How can the slope of the graph be infinity when any x<0 gives a constant y= infinity?(Is it wrong to consider infinity as a single very large...

No, you did everything right except that your car is decelerating so your a value should really be -5.88 and that would give you a positive vi value.

I was confused because I thought R2 R3 were connected in parallel, but I see why they are in series now. Thanks

Homework Statement [b]2. Homework Equations Q= Q0(e^(-t/RC)) The Attempt at a Solution I need help for part C.I am confused as to what value I should put for R. The answer is supposed to be .166 seconds

Are you familiar with l'hopitale's rule? if lim (x->0) a/b = 0/0 or infinity/infitity then lim (x->0) a/b = lim (x->0) a'/b'

Homework Statement Find the area bounded by the curves given by the graphs x = 4 - y^2 and x = y^2 - 2y The Attempt at a Solution I don't know how I can integrate these curves as they are not functions. Can someone tell me to get started on this problem? Thank you

Everything is right except you're not supposed to use n oil and water but rather n air and oil, because the ray is coming from above in air and not from the water right?( I think this is a trick question or something) So your new wavelength would be 556/1.33 (n air is 1) = 444 and you should get...

If you use m=4 that is 4+4+1 which only gives you 9 fringes. The question doesn't say these are all the possible fringes, maybe only a part of all fringes. What I would do is use m= 9 (that is 10 because we include m=0) and use distance y as 1.65cm. And yes you are supposed to use (m)LaTeX...
