Ease yourself by preparing for AIEEE without much bothering about the distribution pattern...

If I say Mechanics has a greater weightage, then that doesn't means that you will leave out Calculus part since Kinematics requires lot of Calculus...

Hope this will ease your tension

Thanx...

Soln:-
2004-24=1980

1980=2^2*3^2*5*11

therefore, no of factors=(2+1)(2+1)(1+1)(1+1)
=3*3*2*2
=36

hope it solves your problem...If there is any doubt please post it..

please rate for what I have done...

The statement is absolutely wrong..

v=constant
that constant turns out to be 'c' i.e. speed of light.
v=c/

therefore frequncy is inversely proportinal and not directly..

thanx

I have checked my soln, still I am getting 630m/s.

Pl tell me how did you get 444m/s

The mass on the right will be nearer because velocity 'v'(i am assuming it for convinience) is given to the right mass
therefore, the tension will develop in the string with a effect of Tsin=m(v-u)/t
but initial velo.=0
Tsin=m(v)/t.
but v is linear proportional with distance....
Therefore, the length of string increases on the right part since tension is developed and the string is same.

This is the soln, if you have any doubt please free to ask me..
Please rate for what I have put in....

Thanx..

tan(C/2)={/s(s-c)}

tan(C/2)=c^2-(b-a)^2/s(s-c)

tan(C/2)=(c+b-a)(c-b+a)/s(s-c)

tan(C/2)=2(s-a)2(s-b)/s(s-c)

tan(C/2)=4(s-a)(s-b)/s(s-c)

4{tan(C/2)}^2=tan(C/2)

tan(C/2)=1/4

In ABD and ACD

using sine rule,

a^4+b^4+c^4=2c^2(a^2+b^2)

a^4+b^4+c^4-2c^2(a^2+b^2)=0

a^4+b^4+c^4-2c^2(a^2+b^2)+2*a^2*b^2=2*a^2*b^2

(a^2+b^2-c^2)^2=2*a^2*b^2

taking sqrt both sides,

(a^2+b^2-c^2)=+2*a*b.............(i)

or

(a^2+b^2-c^2)=-2*a*b............(ii)

using cosine rule,

cos(c)= b^2+a^2-c^2/2ab...................(iii)

Substituting (i) and (ii)

we get,

cos c= 45 or 135

therefore ans(B)

The answer is irrrational because whenever you take P less than 2, there is exists a number B which adds up to it...........

Q1)
x3+27=0
(x+3)(x2-9x+9)=0
x=-3 or x=9sqrt(45)/2

(c/a)2=126-18*sqrt(45)/36
(b/a)2=126+18*sqrt(45)/36

(c/a)2+(b/a)2=7
(c/a)2*(b/a)2=418.5

therefore eqn is x2-7x+418.5=0

Q2)
By completing the square method, you get the condition, k<16
I think answer may be 4...

If the gas is monoatomic, then answer is 2R, if diatomic then 3R....

formula:- c=R/(cp/cv)-1- R/n-1,    where n is the co-efficient of V on the question....

Ans:- 5.61 Hours

Soln:-

v(avg)=sqrt(8RT/piM)
sustituting the values, we get,
v(avg)=630m/s
diamter of earth=12732km=12732000m

therfore, time=12732000/(630*60*60)=5.61 hours

according to ist kinematic eqn,
v=u+at

But IInd says that
s=ut+.5at^2
here taking out 't' common and dividing we get,
v=u+.5at

What causes the diff of .5 at in both cases
