 water has the max density at 4 degs... obviusly denser substances tend to go down compared to rarer (les dense in comparision) substances.. so frm abt normal cold temps..say around 10 degs ...when water cools down it tends to 'sink'..it dusn sink but due to convektion curents..the coold water goes down and water which is rares come up... this way it continues till the whole pond is at 4degs.. after that.. the convektion stops..and on further cooling..no doubt tht the density deks as still temp dec..even the water dusn move also now that its rarer than the 4 degree water... so the top layer freezes... and since ice is a bad conduktor..it prevents the quick freezing of lower layers(in comp with the tym taken for the uper layers to freeze after the whole pond is at 4degs) so it apears it freezes frm top to bottom...

hey actualy y wud the water even flow out? there wont b presure diference if im not rong coz P=hdg...here actual acceleration is 0 (reference) so ther wont b presure dif... n water remains inside... coz center of mass has 0accel n initialy at rest... asuming the buket is droped exactly at the instant the hole is made...

Catalogs Discussion Forums -> Mechanics -> Why is during the rainy season...when rain falls on the car...the rear window remains dry. -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
its bcoz when the cars moving..due to the effective velocity of the car, the rain drops make an obtuse angle with the car(if u draw a normal to the car on the top,the rains come from the second qyadrant to the origin{apear to})...so depending on the angle of the rare window it either gets wet or does not..the probabilty of getting wet depends on the velocity of the car and the angle of the window...if the car's rare window is straight i.e paralel to the normal,then it can never get wet...if the speed is less and the angle of window is more then more chances of getting wet and if the angle is less and the speed is more less or no chances of getting wet...

arihant is a really cool book for calculus..it has earthshaking problems and is a very very good practise..

but the solutions given sometimes are crap and mosly even trivial sums are done a page or two(duno if the author is an idiot as the trivial nature is clearly seen)

and a few(not many) are really n completely wrong Qs and are not print mistakes...so if you can correct the sums urself u can go ahead fearlessly..

the whole messege is to say that some of the sols n probs of arihant are not realy corect so if u don solve or understand them u don have to worry..

and talking about arihant..the vectors and 3d geo thng by amit agarwal is a cool collection but has terrible mistakes..a typical example of wat i was saying earlier..

and besides these buks don giv a clear explanation of the concepts whch myt b needed in an emergency(in case of confusion or iregularity to coll)

this buk is worth the buck..though

u could also try calculus from pearson ed written by thomas and finney..it gives really hot concepts and makes u a champ and not only abt calc it also has other really basic n elementary prerequisites and also contains vectors conic sections etc..a real gem of a book..

The Indian Institutes of Technology

The Indian Institutes of Technology is another name for IIT, which is the acronym for Institute of Infinite Tension, Institute of Indian Technology, etc. These institutes of so-called national importance were set up by the Indian Parliament at seven campuses across India, decided purely on merits of political alliances of the ruling party. It was the mastermind of a certain Jawaharlal Nehru to reduce the average intelligence of Indians that led to the establishments of these institutes. Just like Zion in Matrix, where 3% of the people who do not accept the Matrix are gathered together to prevent dissent as a whole, IITs were formed by the Government of India to gather at one place the 2% of the intelligentsia of the country and dumb them down.

Admission

The geeks and nerds of India start preparing for IIT-JEE just after 10th standard of schooling. A very effective test of whether a guy is fit for getting into the IITs is asking a very simple question: "Do you have a girlfriend"? A guy who says anything else other than "What's a girl?" would not get through the test. Girls are considered unfit to get into IITs, though some girls manage to get the application forms as they look like guys. To make sure no girl gets through the system by bribing to get the application forms, the applicants are required to specify their gender and affix a photograph in the application form. Those faces that resemble anything girly are not selected.

The entrance exam, IIT-JEE, is an extremely selective undergrad admission process (accepting less than 2% of their applicants). As they say, if the input is right, the output is automatically right. The six-hour Joint Entrance Exam held, as the name suggests, jointly by IITs, consists only of questions on Physics, Chemistry and Maths and not on other exotic details like Booze, Drugs, Crime, Pr0n etc. which severely affect the quality of the incoming students. Since the Indians are well known for cramming up loads of information, questions in JEE are never repeated.


Education

The IIT curricula is carefully decided so that there is no scope of learning anything. The students, then, take up alternate learning routes, most common being Pr0n. The IIT alumni on knowing the tremendous potential of internet, provided all hostel rooms with free and unlimited internet connection. The IIT administration tried to propound their agenda by putting lecture videos on the LAN, but this is yet to be confirmed as this has not been tried by any student. The IITians are also forced to eat mess food, that prepares them for the worst they can ever face in their life.

The guys also learn how to make 50 palladins in 25 minutes and get three frags per shot. Some of the creative minds also make a quick buck by selling MMS clips online. Since there are assignments to be submitted every now and then, the guys also learn how to use Google adeptly. Photocopying centres are provided for every 100 metres of road so that time wasted in photocopying assignments is minimized. Lecture classes are held from 7:30 a.m. to 5:30 p.m. IST (Indian Stretchable Time). It has been established by years of testing that the time can be stretched to as much as 30 minutes beyond provided it is backed by a cardinal excuse. The summary and results of many such experiments has been documented well in a book by an IITian titled "Five Point Someone: What not to do at an IIT". The book also deals with complex issue of dealing with a girl in IIT.


Life and culture (or lack thereof)

When entering the IIT, a guy has two options. The first is to take up the common learning route described above. Since IIT-JEE makes sure a lot of mavericks are selected, many of them also end up being happy among themselves. The girls in IITs, usually refered to as Non-Males and measured as parts of girl per million parts of guy, have to struggle keeping their identity as girl secret throughout their stay in IITs. Sometimes they are forced to tell the truth, like when a gay IITian proposes mistaking them for a guy.


Alumni

The alumni of these institutes have been very sucessful across the world (more in USA than in India). Most of them either get frustrated and leave technical education to study management at IIMs, or start a company of their own totally unrelated to their major discipline. There are also a select few who develop a fetish for studies and end up in institutes like Massachusetts Institute Of Technology. An interesting aspect is that, alumni of these institutes form the second-largest graduate student group at MIT, the largest being MIT undergrads and one day hope to colonise the whole of MIT campus.

an article of intrest:

Death of the Dinosaurs

Science, these days, thinks Dinosaurs were killed off by some massive world-wrecking force. Like a meteor or a vicious band of Hyper-Cubes. Me? I think differently. See, this science, it thinks it can be all super smart and all, but I've got the inside scoop. I do.

There was a fatal flaw in the plans of the Volcano Island Mountain scienticians, one which they had not at all anticipated, and that was this: competition. Little did they know, a certain Evil, Inc. had not only already completed and sent back The Terminator and George W. Bush, but they had also almost finished their super-secret Project Anti-Christ to thwart the plans of Jesus. Jesus Christ. Who may have been a dinosaur.

Finally, after years of fruitless court battles over the patent to the time machine, Evil, Inc., created a vicious army of dinosaur-killing robots (the Terminator) and destroyed the dinosaurs. All of them. Except raptors, who live underground these days.

So...I guess I lied about the punishment from the God. For proving it wrong. About the world being around for only five thousand years.

Another theory holds that over the top kitten huffing killed off the dinosaurs, but if you think about it, mammals were rare, so there wouldn't be any evolution...

Whatever the case, however, there is good evidence that the spirits of many dinosaurs may have been responsible for shaping human history through possession and genetically engineering White and Jewish people to be autistic savants, allowing the dino-demons to form public opinion and possess world leaders.

It is also a popular theory believed by scientists around the world that the dinosaurs died because you touch yourself at night, but this wouldn't make sense because as everyone know, masturbating kills kittens, who are mammals, and in this time period, would by genetics mean you wouldn't exist, but genetics doesn't matter to you, obviously, since s e x is designed to spread genetics, and frankly, you seem to be doing fine without a partner.


Yet another theory says that the dinosaurs died when tomato sauce was created by the Flying Spaghetti Monster and was sent into the earth at high velocities, killing the dinosaurs and giving the primates intelligence.


Yet another theory is that one day gravity simply stopped. All the dinosaurs outside floated off into space leaving only dinosaurs in caves, who thought "Hmmm, I must start theorizing gravity or I'll never be able to go outside and watch the trees grow." So they made a ship from unobtainium, travelled to the centre of the earth and planted nuclear charges to start the nucleus again. This is where Jules Vernes got his idea, 'Journey To The Centre Of The Earth' from. Unfortunately, all the unobtainium was used to create this ship so we can never actually venture into this realm to find out if this is true, which it is. Anyways, when the dinosaurs restarted the core all the dinosaurs that floated off came back at tremendous speeds. These then turned into flaming skeleton comets, which is where the most popular theory comes from, and also fossils.








PS:this is just for some recreation..no offence meant..those without comedic tastes myt jus keep quite.
