y = cx - bx2


differating it


u get vy  = (c-2bx)vx-------1


again differatating u get


a = 2bvx ^2------------2


solve 1,2 fr vx , vy  


so with da values of vx , vy


u can find velocity at any point

q no. 2 angular velocity = V/R = 5/1 = 5m\s


both centripetal and centrifugal force dont act in a same fram of reference only depends on ur frame of reference


considering an interial fram of reference the force will be centripetal


so centripeatl force MV^2/R = 25N


 q. no 3 orbital velocity of a satilite = root over GM/R u will get this by equating centripetal force and gravtional force by earth


where M is mass of earth and r radius of  earth G gratitatinal constant


sole further


well wats m.a. and v.r. in the first ques

consider a plate ,a part of which is in maganetic field. now consider a loop drawn on the plate which is in the field now as the plate moves maganetic flux varies as area covered varies and hence current is induced . further there may be many such loops on the plate so currents are induced on the surface along various paths these currents are called eddy currenrs

Manipal is quiet a good collage with ur rank u cannot hope fr CSE n ECE  well u will get a seat certainly  don worry  u can hope for it or mech.  u know  thogh he has called only uptil 6000 there will be even a 2 conselling coz there r more droputs at the counselling. well there is no capitation fee in manipal . also check out the fee structure of manipal in the brochure given its expensive

READ THIS SLOWLY :
"GODISNOWHERE"

what did u read god is now here or god is no where. a simple illustration to show that things depends only how u take them.
according 2 me Difficulties r those things which arise when u take off ur eyes from ur goal. so forget all whatz happening around u , and do not ur big dream, JEE .
come on priyanka difficulties r a part of life , i too have faced wholesome of them. keep on going!!!!!!
and do remember don't Differentiate ur confidence , instead integrate ur confidence

hey tejasvi2389

i don't have solmons but i have gone through it once. i am even confused even wit the system in ths book can u pls guide about the order of the chapters in solmons
Catalogs Discussion Forums -> Mechanics -> show me the IIT'ian inside u !! how does the thrust force come as pav2 ?? -> Go to message
This Post 5 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]
for mass decrasing or increasing system the magnitude of thrustfo (dm/dt)*v relative.

dm/dt = mass flow rate = pav

hance thrust force = pav2

i don think itz like thist nikhilwalani , this is a mass decreasing hence there will be a thrust force acting on it which is givem by pav 2. where p - denisty of fluid, a - area of crossection, v velocity . but the prob here is the area of crossection and velocity are gradually changing u have 2 apply integrations help me out at this

now even though i go with ur method the velocity is gradully changing at each point
i have to apply integrations even for this

hi guys i am harry
I have bought R.T.Morrison and R.N.Boyd for organic chemistry , but i am not able to follow it. beacuse the order and context of lessons in it is not like other books like O.P.Tandon for eg. u don't have a separate chapter called Reaction mechanism in morrison and boyd. someone help me out how 2 follow this book
