Define: weight(W)

Answer the following questions : Define weight . State its SI and CGS units.

One end of uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight W_(1) is suspended from its lower end. If s is the area of cross section of the wire, the stress in the wire at a height ( 3L//4 ) from its lower end is

The weight W of a certain stock of fish is given by W = nw, where n is the size of stock and w is the average weight of a fish. If n and w change with time t as n = 2t^(2)+3 and w=t^(2)-t+2 , then the rate of change of W with respect to t at t = 1, is

A wire elongates by l mm when a load W is hanged from it. If the wire goes over a pulley and two weights W each are hung at the two ends, the elongation of the wire will be (in mm)

A ring of radius r, and weight W is lying on a liquid surface. If the surface tension of the liquid is T, then the minimum foce required to be applied in order to lift the ring up

Spheres of iron and lead having same mass are completely immersed in water. Density of lead is more than that of iron. Apparent loss of weight is W_1 for iron sphere and W_2 for lead sphere. Then W_1/W_2 is

Statement-1 : A body weight W newton on the surface of the earth. Its weight at a height equal to half the radius of the earth will be 2 W//5 . Statement-2 : g' = g.(R^(2))/((R + h)^(2))

Define angular velocity. Show that the centripetal force on a particle undergoing uniform circular motion is -m omega^2 vecr .
