K.C.S.E Physics Q & A - MODEL 2016PP1QN10Figure 8 shows two cylinders of different cross-sectional areas connected with a tube. The cylinders contain an incompressible fluid and are fitted with pistons of cross-sectional areas 4 cm2 and 24 cm2.
Opposing forces P and Q are applied to the pistons such that the pistons do not move. If the pressure on the smaller piston is 5 N cm2, Determine force Q.

(a)An aeroplane is moving horizontally through still air at a uniform speed. It is observed that when the speed of the plane is increased, its height above the ground increases. State the reason for this observation.
​(b)Figure 6 shows parts A, B and C of a glass tube. 
​State with a reason the part of the tube in which the pressure will be lowest when air is blown through the tube from A towards C.
answers
​(a) Increase in the speed of the plane decreases the pressure of air above it while the pressure below it remains high. This leads to a resultant upward force
(b) Point B The velocity is high at this point hence pressure decreases K.C.S.E Physics Q & A - MODEL 2016PP1QN07
​Figure 5 shows an aluminium tube tightly stuck in a steel tube.
Explain how the two tubes can be separated by applying a temperature change at the same junction given that aluminum expands more than steel for the same temperature rise.

​Figure 2(a) and 2(b) shows capillary tubes inserted in water and mercury respectively.
​It is observed that in water the meniscus in the capillary tube is higher than the meniscus in the beaker, while in the mercury the meniscus in the capillary tube is lower than the meniscus in the beaker. Explain this observation
