    Neurtal hydrogen atom net electric charge and electric field at Bohr radius.

    I am studying for my exam and I have run into this problem. The problem is given here http://faculty.mint.ua.edu/~pleclair/PH253/Homework/Spring_2010/HW6-7_atoms_12Mar10/HW6-7_atoms_12Mar10_SOLN.pdf"],[/PLAIN] it is #9. I don't understand why -e ≠ ∫ρdV from 0 to the bohr radius, a0. If all...

    Hoping to study physics - do I have to start over?

    Im sure you won't have to go back and complete all of your GE courses. Transferring credits from your original bachelors should fill those in. As someone above stated community college would be a good choice to get most of math and introductory physics classes out of the way, dif eq, calc 1-3...

    Emailing professors for an interview about joining them for research

    I went to my current physics professor and asked about starting to do some research. She gave me a list of the research experimental faculty and said to email them just asking if they would be interested in having me, and asking to meet with them in person. I am just wondering on exactly...

    Is a Course Load of 3 Math and 1 Physics Class Doable?

    What i took this semester was Physics II(e+m) with the lab, calc 3, linear algebra, and discrete math. I have to study a lot but that's what college is all about. Also my grades are pretty good. But if you working a lot i would not suggest this.

    What extra math classes to take?

    I am currently getting a physics BS. was going to double major in math but am going down to just a minor due to the huge work load the latter would be. the class i can't get rid of is an introductory proofs class. and i then have a choice between advanced calc (calc proofs), abstract algebra, or...

    Solve Latent Heat Problem: Mass of Injected Steam

    Homework Statement Steam at 100°C is injected into 1.8 kg of water at 22°C in a well-insulated container, where it condenses and mixes with the existing water, reaching thermal equilibrium. If the final temperature of the well-mixed water is 25°C, what is the mass of the injected steam...

    Simple hanging tension problem

    bleh yes first time post. and the equation read T1y+T2y=0 should be T1x+T2x=0. and T1x+T2x+W=0 should be T1y+T2y+W=0. also i used 120o only because my book gives an example of a similar problem and also does this but that example on solved for one side.
