WAEC Theory Questions Part II
PART II
[45 marks]
Answer any three questions from this part.
All questions carry equal marks.
8(a) Define uniform acceleration,
(b) Forces act on a car in motion, list the:
(i) horizontal forces and their directions;
(ii) vertical forces and their directions,
(c) A car starts from rest and accelerate uniformly for 20s to attain a speed of 25 ms-1.
It maintains this speed for 30s before decelerating uniformly to rest.
The total time for the journey is 60 s.
(i) Sketch a velocity-time graph for the motion,
(ii) Use the graph to determine the:
(α) total distance travelled by the car;
(β) deceleration of the car.
(d) The figure here illustrates force-extension graph for a stretched spiral spring. Determine the work done on the spring [download document below to see the image]

9. (a) List two factors each that affect heat loss by:
(i) radiation; (ii) convection,
(b)State two factors that determine the quantity of heat in a body.
(c)Explain the statement: The specific latent heat of vaporization of mercury is 2.72 x 105Jkg1.
(d)A jug of heat capacity 250 J kg-1 contains water at 28°C
An electric heater of resistance 35Ω connected to a 220 v source is used to raise the temperature of the water until it boils at 100°C in 4 minutes.
After another 5 minutes, 300 g of water has evaporated. Assuming no heat is lost to the surroundings, calculate the:
(i) Mass of water in the jug before heating;
(ii) Specific latent heat of vaporization of steam.
[Specific Heat Capacity of Water = 4200 Jkg-1 K-1]
