Yes. Sorry I forgot to take the square root so yea a typo. But to be honest, I don't get what you are saying. Could you be more specific in where I am going wrong?

Homework Statement [/B] Determine the rectangular and polar radii of gyration of the shaded area about the axes shown. Homework Equations dIx = y2dA Ix = ∫y2dA dA = ydx A = ∫(dA The Attempt at a Solution dIx = y2dA =(x6/16) *(x3/4) dx =(x9/64)dx Ix =(integrating from 1 to 2) ∫dIx =...

The problems says certain charge density is acquired when subjected to electric field. Nothing else at all

I had this problem in my exam. It required me to calculate relative permittivity of a dielectric slab which acquires a surface charge density of 800micro Coulomb/m^2 when subjected to an electric field of 10^8 V/m. Applying E=sigma/(2epsilon), I got relative permittivity as 0.45 which is less...

The problem is to apply Schrödinger wave equation to a beam of mono energetic electrons and show that the probability of finding electron at each point on the beam is constant (d2ψ/dx2) + (8∏^2m/h^2)(E-V)ψ = 0 I have been taught to apply this to a single particle for various...

I'm sorry for the mistakes. I just did the whole thing in a very short time and so there are mistakes. Just wanted to know the method. And sure, I will try by your method

I did this.. I would be glad if the method is correct :)

I was thinking if the 10 ohm resistor (horizontal position in the image) should be removed, because if we analyse it from Wheatstone bridge's point of view, no current flows through it. I maybe wrong. Help appreciated.

I am unable to proceed. Please help me by describing how to solve it(and the method and reason behind the approach) Thank you

Alright so, I ordered Feynman's book hoping to begin QM without much mathematical knowledge. I currently have Halliday, Rensick and Walker textbook. Will the little QM in it be sufficient or should I go for Arthur Beiser for the fundamentals? Also, I would be thankful if anyone told me the...

So is Feynman not suitable as a textbook? How about the QM part of Fundamentals of physics by Halliday, Resnick and Walker? Does it have good explanation?

Hello. I am at my first year of engineering and the syllabus include QM. Chapters covered are: Fundamentals of QM - Wave particle duality, matter waves, phase and group velocities, Heisenberg's uncertainty principle and its applications, physical significance of wave function, probability...

Yes. H-bond is formed again between hydrogen and water molecules but the strength of this bond is weaker than that between water-water molecules. So I am guessing that is why some heat is liberated. Always consider difference in strength of the bonds. Not just the bonds.

Oh I am extremely sorry. It exactly the other way around. Swap places with ethanol and water :) Thanks Sagar
