Radio waves are electromagnetic waves occurring on the radio freequency portion of the electromagnetic spectrum. A common use is to transport information through the atmosphere or outer space without wires. Radio waves are distinguished from other kinds of electromagnetic waves by their wavelength, a relatively long wavelength in the electromagnetic spectrum.

In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. With relation to chemical terminology, aromatic hydrocarbon or arenes, alkenes, alkanes and alkyne-based compounds composed entirely of carbon or hydrogen are referred to as "pure" hydrocarbons, whereas other hydrocarbons with bonded compounds or impurities of sulphur or nitrogen, are referred to as "impure", and remain somewhat erroneously referred to as hydrocarbons.
Hydrocarbons are referred to as consisting of a "backbone" or "skeleton" composed entirely of carbon and hydrogen and other bonded compounds, and lack a functional group that generally facilitates combustion.
The majority of hydrocarbons found naturally occur in crude oil, where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate to form seemingly limitless chains.

well IITJEE is very unpredictable exam so,it cant be said which topic can be kept optional..i think prepare all the topics hardly ...IITJEE have equal weitage of all the topics..

hello deart..
solve the questions and ask me the doubht reagrdin that book..well resnick halliday is the best book for IITJEE and for higher physics

kirchoff laws:
it deals with two things:
1.conservation of charge
2.conservation of energy
KCL:Kirchoff current law;
net incomining current = net outgoing current
KVL:Kirchoff voltage law;
Net algebric sum of the voltage dropped in the close loop or circiut is zero

given equation of parabola is y2=4x ----------------1
and we know that general equation is y2=4a
comparing given equation with the general equation we have a=1
and latus rectum= 4a = 4
hence as per the given condition the ordinate will be twice the latus rectum, hence ordinate= 8
substituting y=8 in equation 1 we get x=16
hence the point is (16,8)
|

|
|
the answer is:
this is th very basic question in analytical geometry and its prove is given in all the staandard text books ..just as NCERT,ML khanna,AD gupta,SL loney
a = X cos @ - Y sin @
b = X sin @ + Y cos @..

hello dear..
i think you are asking inverse of density,i had comprehended by the dimensions in your question..it is known as GUESSIAN PROBABILITY,which is not it the JEE sylabus...if you need to learn more about it..read quantum mechanics..i will guide you the books for it

course of 2009 is known till date..course for 2010 is not till date,it will be known by tyhe notification of JEE 2010 in the IITs websites

le the equation of circle be in standard form
apply the condition of orthogonality of two circles..
put the point in the equation of circle and g = -x & f = -y ,you will get the answer
|
|
|
|
|
here..
dy / dx = -1 ;
it is cleraly defined that put y = -x + c ;

hello dear..
iam giving you the sorce of related to the literature of complex number..

hello dear..
u know that equation of the radical axis of the 2 circle is
C1 - C2 = 0 ( C1 and C2 being eqn of circles 1 and 2 )
that is, 6x + 12y - 6 = 0
or x + 2y = 1
And, u can see that the point ( 3, -1 ) lies on d 2 circles and on the line wich is their radical axis,
hence two circle touches each other at (3,-1)

1.
equation of circle is:
(x-3)2+(y-0)2 = 52
2.
ceentre is (-4,2) ..and the tangent is: x-y=3
distance beteewen tangent and centre is :
d = 9 / 21/2 = radius
find the equation of circler when radius and centre is given
