​Fig. 1 shows a brick placed on a plane inclined at an angle to the horizontal. The weight, W, of the brick is shown.
​a) On the same diagram show with arrows the other two forces acting on the brick and name them.
b) State how each of the two forces named (a) above is affected when the angle is reduced. K.C.S.E Physics Q & A - MODEL 2008PP1QN02The masses of equal volumes of a certain liquid and of water were found to be mv and mw respectively. Given that the density of water is 1gcm-3, express the density, p, of the liquid in terms of mv mw (show your work)K.C.S.E Physics Q & A - MODEL 2008PP1QN01
