Now I have got a method to get it directly.And again it came out to be an easy problem.
Maybe you'll want to try again after knowing the answer to it, which comes out to be:$$I= \dfrac{m}{12}(a^2+c^2)$$
Hint
(You'll get final answer after seeing this image hint , So, if you want to try again p...
There is this famous example about the order difference between gravitational force and EM force. All the gravitational force of Earth is just countered by the electromagnetic force between the electrons on the surface of my feet and the ground.
But also wave-function of electrons(fermions) do n...
I've been wondering, what causes the normal force to exist?
In class the teacher never actually explains it, he just says "It has to be there because something has to counter gravity." While I understand this is true, it never explains why.
Whenever I ask anyone else they always respond in a s...

It happens to most of my questions..! Looks like the MSO fellas should've added a *time-reversal* function to my golden phrases, so that it sends it back in time once they think of "feature-request" or "bug" :P

@ManishEarth: Bad mod..! *personal mail* to SE team..!

@ϚѓăʑɏβµԂԃϔ Youre not the good guy! youre trying to hold back space exploration and keep humanity rooted to earth so you can take over the human race much easier with your unrecogniseable name!
I have thought about this question for quite some time. The theory that I highly believe in is about string theory. The theory states that the space in between subatomic particles are almost massless strings from type 2a string theory. These string have so little mass (roughly .83 x 10 to the -5 ...
Blame Pekka for this answer, he put me up to it ;-) . Enough cats, Pekka?
Yes, we need something linkable. The FAQ is an ideal place for this, but there are lots of other similar things that can go there as well. We don't want to bloat the faq, too few people read it already. Still, this par...
Suppose there is a cuboidal vertical tunnel , and a cubical block in it such that all surface of the block are in contact with the four walls of the cuboidal tunnel respectively . All walls of the tunnel are rough with different $\mu$s . And the weight of the block is $m$ and it is a point mass s...
In the TV show "Breaking Bad", Walter White frequently gets rid of people who get in his way by submerging them in a plastic container full of hydrofluoric acid. This, at least in the TV show, completely dissolves the body leaving nothing but a red sludge behind at the end.
Is it actually possib...
Watching some movie/TV this question came to mind, purely theoretical of course, if one wanted to dissolve a human corpse, like getting rid of a body after killing someone, is it better to use an acid or a base? In the movies (as well the popular perception for some reason) they always use acid. ...
Easiest way to dispose of a body is the giant silo's where you store farm animal waste! The large vertical ones. Ain't nobody gonna be searching through that, or wondering what the smell is
Is there any absolute constraint (don't confuse me with a wavefunction - I don't believe in GOD playing dice :P ) for "which questions get >10 votes" every weak so that I may introduce a low-quality-answer and get to the top ??? :P
I was attending my philosophy class and in the middle of student presentations, I found myself mentally wondering off and thinking about light. After a few minutes of trying to piece together how the sun works I came to ask a question I could not answer myself. Why does each individual photon hav...

The framework of newtonian mechanics is complete -- there's no such thing as "newton's laws can't solve this" for nonrelativistiv/non quantum situations
@nonagon There is such a thing as overidealization
For a Reissner–Nordström or Kerr black hole there is an analytic continuation through the event horizon and back out. Assuming this is physically meaningful (various site members hereabouts think not!) does this change the genus of spacetime?

This site is filled with non-physicists asking non-sensical question without any actual background in that topic and they expect answers without mathematics and kind of general intuition , not even intuition w.r.t. to that particular topic and this kind of attitude is promoted here .

Well learn mathematics first and learn laws and then work out these situations yourself , if still you can't do then ask according to homework policy , that shows that someone actually wants to learn . There are already plethora of pop-sci material on internet , search on youtube or google the info. It is equivalent to spam for me .There are a handful of good people running the site really and handful of questions are asked everyday which actually have potential of actually learning something

and yes 007 i have no problem with you , your answers and questions are unto the mark and I have learned quite a lot from your posts as well . So thank you even though we fought a lot . Now since these non-physics people won't leave its better I do since I don't enjoy such an environment here
and its better you start , physicsfordummies.stackexchange.com here to entertain such people . And stop worrying about reputation here , this site is for you to learn and teach rather than earn a certain number of digital points which are of no use in real-life .
And just delete my account , I don't want to be part of this community anymore .
But, if the only people who were allowed to be here, were those with extensive knowledge of physics, there would be no questions, as everyone would know the answer
And those who are going to get angry at this are the ones who ask these sort of useless questions here . So , let me tell you . I don't care about what you think or say
@nonagon I'm not going to argue with you, you are entirely allowed to have that opinion, but what i am going to say, is that if you dont care what others think or say, dont expect anyone to extend that courtesy to you
Ask legitimate questions , A question like blackholes do so and so with time , without ever studying general relativity is kind of irritating and it reflects the attitude that you want such an answer that satisfies you but not an answer which is actually the true one .
In Hiroshima, atomic bomb was dropped, but today, there are residents in Hiroshima. However, in Chernobyl, there is no resident living today (or very few). What made the difference?
