Ah I see, I thought that they were considered optional as I had several conflicts with scheduling. Thanks for your information

I said they were optional panels, if that's the reason I failed then I'll take the fail. But I feel like when they say "optional" then that is supposed to be the case. Edit: I said the class consisted of those two.

It consisted of showing up to class and attending optional seminars and panels. I went to 3/8 of the panels and 4/5 of the classes. Still unsure why that constituted a np. But I emailed my professor and he's a genuinely nice person, so I'm hoping it was a mistake or something of the likes.

Didn't really talk in class, was shy

Thanks for your guys' insight. I'm just hoping that it turns out to not be that big of a deal as I feel like a one unit class that doesn't pertain to my major requirements or prereqs will not have such a big impact later on.

Great...Would it be worth my time then to contact the professor and try to get him to change my grade?

Hi everyone, so I goofed. I ended up taking a pass/no pass one unit course at berkeley called the berkeley connect program for physics. The class was designed for physics majors to collaborate and talk about physics and do activities and such. So I ended up not passing the course and I'm...

Hi everyone! I was wondering if I could get some help with regards to a possible change of plans. I am currently a junior at UC Berkeley majoring in physics with a ~3.6 gpa. My original plan was to pursue a physics PhD but I may wish to apply for a masters degree in engineering specifically...

Homework Statement A rope is wrapped through an angle θ about a horizontal pole (So for ex- ample, θ = 2π would imply the rope goes around one full time). The rope and the pole have a static friction coeffecient of μ, and the pole is of radius r. From one end of the rope hangs a mass m. How...

Wait, why exactly would the accelerations not be opposite for these masses? If the pulley system is moved up, wouldn't they be affected in opposite directions? I would think that the lower pulley's acceleration would be the opposite of the acceleration of mass c.

So I believe that the acceleration of mass B is the negative of mass A; or aa = -ab. But I have looked into how the system would react to m3 accelerating downwards with a constant string length, and I just cannot understand it. Like, I want to believe that as m3 moves down a distance L, that the...

Homework Statement The double Atwood machine has frictionless, massless pulleys and cords. Determine (a) the acceleration of masses ma, mb, and mc, and (b) the tensions Fta and Ftc in the cords. Homework Equations F=ma The Attempt at a Solution So I drew free body diagrams for the mass A...

Ah ok, the original equation should have been t1 + t2 = (750/cosθ) - (400sinθ - 200)/(cosθ). Then when I took the derivative, I forgot to distribute a sinθ. It should have been (950sinθ - 400)/(cos^2θ) = 0. This gives me θ to equal 24.9 degrees. Finally done with this problem. Thank you so much...

Ok when I take the derivative, the equation comes out to be (750sinθ + 200)/(cos^2θ) = 0, That would mean θ is equal to 15.5° which isn't the correct answer

...I have taken calc just this problem is kind of difficult in its own way. No need to be condescending my peers couldn't figure this out either who have also taken calc...all I wanted was some help in case I was missing out on a detail or something.
