plzz tell the method

A small solid sphere rolls down the hemispherical path...Find the angle at which it breaks-off ...the sphere.....

NOTE:The sphere rolls down and does not slide...

hiii...can anybody tell me how can i find the rate of a reaction experimenatlly in lab and plot graph of concentration vs. time and find rate of that reaction...

I HAVE TO DO IT FOR MY SCHOOL PROJECT

PLZZZ TELL ....

IF U CAN EXPLAIN PLZZZ EXPLAIN FOR HYDROLYSIS OF ESTER WHICH IS A PSUEDO FIRST ORDER REACTION

What is the angle between the directions of electric field at any  equitorial point due to an electric dipole?

ans is 180^o

plzz explain.........if possible with a diagram

Yarr in rolling motion in which direction should be the fforce of friction be considered..... please explain how to see the direction of frictional force plzz......explain exhaustively......

yarr karthik friction is stopping the disc................

all the relevant info. is in the diagram i think u will understand it...if not nudge me.....

just see the components and apply conservation of linear momentum in the direction of componenets and u will get the answer.........

the vcosα component will pass through the centre (centre of mass) of the sphere.........
