To rl.bhat Thanks. I tried to follow your instruction. Integration of x^n*dx = a*dt gave me (1/n+1)x^(n+1) = v. I didn't find x in terms of a, n and t.

Homework Statement The velocity of a ball of mass 'm' varies with the distance v(x) = ax-n, where a and n are positive constants. Determine F(x), x(t) and F(t). Homework Equations F = ma a = dv/dt v = dx/dt The Attempt at a Solution If velocity were the function of time, i...

I am confused about operators and eigenstates. What does "an operator has two normalized eigenstates" mean ? Is there a way I can make a physical interpretation ? How are measurements made with these ?

Hi Doc Al, could you explain a bit more ? Thanks

Interesting. What if there was a blockade of some height (less than the radius of the wheel) was on its way? On that case how should one calculate the minimum force so as to just lift the wheel off the ground ? Any idea ?

actually that's where I'm stuck at. I know its should be something simpler but my system has lasted on me...

replacing alpha with A beta with B gamma with M theta with N I have, 2(Aeikx + Be-ikx) = -Meikx + Me-ikx + Neix + Ne-ix

Homework Statement For a free particle, i have two expressions. \varphi(x) = \alphaeikx + \betae-ikx and \varphi(x) = \gammasin(kx) + \thetacos(kx) I have to determine expressions for \gamma and \theta in terms of \alpha and \beta. Homework Equations sin(kx) = (eikx -...

Hello, I am a senior and am planning to go to a physics gradschool. Looking at several forums and tips online, I came to know that it is good to contact faculty members of prospective gradschool. But I am not sure how to start the conversation, like what to talk about and how. What should i...

If t was time period then t = 2*pi/omega, but from the question it sounds like t could be any time.

The question was made by my professor. So, that's all the info. it gives us. It reads exactly like this: If you are using a parallel RLC circuit with omega as the frequency of the power supply, I and V as the total current and voltage of the circuit, write down an expression for the power...

sorry, I was vague. So, omega is the frequency of the power supply. I and V are the total current and voltages of the circuit. L, R, C are the inductance, resistance and capacitance. I have to find power consumption due to the parallel LCR circuit for a time 't'. I am told to express the power...

Homework Statement How do one calculate the power in time of RLC circuit in parallel combination running an AC current ? It has to be in terms of frequency (\omega = 2 \pi f ) Homework Equations \omega = 1/ \sqrt{LC} The Attempt at a Solution I started off with the omega but...

Hello, I am a senior now. I have a B+ in one of my upper division physics classes. How can I still get into a good graduate program ? Its freaking me out.

Howdy! I am taking Phyiscs GRE next semester and won't have taken classical mechanics by the time I take the test. I am not comfortable with the situation. Can anyone please suggest me a good preparation strategy for me ?
