in moment of inertia  = Mr^2

 

only variable is r (diatance bet axis and obj)

 

r same along circle. ans is circle

simple...........

slope is opposite/ adjacent

so V/I is R

 

ohms law.

thanks.

please someone tell if it is the correct answer.

great job Ken.

what about the answer for the Q. i asked??????

 

i am unable to arrive at the answer.

 

answer:

 

g(f(x))    =       (x+1)²              -2<=x<1

                      x+3                    x=1

 

please help me how to find composition of two functions.

 

eg:      f(x)  = x+1    x<= 1

                    2x+1   1<x<=2

 

g(x)  =  x²        -1<=x<2

           x+2       2<=x <=3

 

how will u define fog(x) and gof(x)

 

please explain without using graphical representation method.

 

 

 

Na2CO3  +  NO2  -----

please help me.

 

 

and Ca(OH)2 + H2O---- CaO

right??

please answerr soon!!!!!!!!!!!!!!!!!!!

 

you'll defenitely get rated.

a uniform mass M length L is held vertically smooth horisontal surface.

when the rod is released choose correct alternative.

 

1.  CM accelerates vertically

2.. initially, magnitude of normal reaction i s Mg

3. when rod just  becomes horizontal magnitude of normal reaction i s Mg/2

4. when rod just becomes horizontal magnitude of normal reaction i s Mg/4.

 

please do explain.

a table tennis racket has a flat rectangular handle of mass m length l

flat circular disc of radius r mass m attached to handle.

Moment of inertia of the bat about axis perpendicular to its plane and passing through the centre of   mass is.......

 

please do give me hints

a rod is held vertically and is given a slight push. when it falls

what is the maximum force on the pivot?????? at which point is it experienced?

please answer soon.........

find dy/dx

 

1) x=sin ³ t / sqrt(cos 2t)

   y= cos³ t/ sqrt(cos 2t)

 

 

2)  x= a (cos t + log tan( t/2) )

  y = a sin t

 

3) x= (a^sin^-1 t)^1/2

  y = (a^cos^-1 t)^1/2

 

please help !
