Consider an inclined plane with inclination theta (Q) with a mass m on it . If we balance the forces , we get N = mgcosQ .I T IS ONLY CORRECT And ,NOT the other way , we get NcosQ = mg,becuse the body is in in equilibrium in the direction perpendicular to incline and not in the direction of mg.
pls RATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11

it will increase continuously if the temp, is above critical temp,of the corrs.,liquid phase of the vapour.
first increases and then remains constant if the temp, is below or equal critical temp,of the corrs.,liquid phase of the vapour.
pls rate!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

well jalanshruti the particle will move about any point on the circle with radius as 2r if its is always diametrically oppo.to the fixed point .but the case is diff.
Here is correct solution.
Let the angular velocity of any body in circular motion be  about the center of circle .but d /dt of the particle about any point on the circle is equal to /2(any arc subtends on the centre twice the angle subtended at any point on the circle )
=v/r(about centre)
/2=v/2r.(about any pt. on circle)
please rate me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A fluid with viscosity  fills space between two long co -axial cylinders o radii R1 and R2 , with R1 < R2. The inner cylinder is stationary while the outer is rotated with angular velocity 2.The fluid flow is laminar.Taking into account that the friction friction force acting on a unit area of a cylindrical surface of radius r is defined by the formula  =(  /r ).Find angular velocity of the rotating fluid as a function of radius r.

Two cylindrical tanks having cross sectional area A and 2A are kept on horizontal floor. First tank is filled with water to a height H and the other tank is empty.If two tanks are connected by a pipe of cross sectional area a(a << A)at the bottom at t = 0, calculate time t when level of water in two tanks becomes same.

hi option c is of course correct.
