00:00 Introduction 0625_w22_qp_43
00:26 1. An aeroplane accelerates along a horizontal runway before take-off.
The aeroplane accelerates for 35 s. The speed of the aeroplane when it takes off is 72 m / s. Fig. 1.1 shows how the speed of the aeroplane varies between time t = 0 and t = 35 s.
02:40 2. Fig. 2.1 shows a tennis ball approaching a tennis racket. The tennis ball hits the racket at a speed of 52m/s. The average force on the ball during the time that it is in contact with the racket is 350 N. The speed of the ball after it leaves the racket is 26 m / s in the opposite direction to the initial speed of the ball. The mass of the ball is 58 g.
(a) (i)
Calculate the change in momentum of the ball while it is in contact with the racket.
05:14 3. Fig. 3.1 shows the cross-section of a barrage built across a tidal bay. The barrage is part of a tidal
power station.
06:36 4. (a) Fig. 4.1 shows a liquid-in-glass thermometer labelled thermometer X. (i) State the physical property which varies with temperature in a liquid-in-glass thermometer.
08:19 5. (a) Three identical dishes, A, B and C, contain an equal volume of water.
Dish A is outside in sunlight and experiences no wind during the day. Dish B is outside in sunlight and experiences a strong wind during the day. Dish C is in a dark room. (b) Define specific latent heat of vaporisation.
11:26 6. Fig. 6.1 shows wave crests and the direction of travel for a water wave approaching a barrier in a
large ripple tank.
13:12 7. (a) State what is meant by total internal reflection. Fig. 7.1 shows a ray of light from a light source in a tank containing a liquid.
14:53 8. Fig. 8.1 shows apparatus used to charge a metal plate by induction. (a) Describe and explain how the apparatus shown in Fig. 8.1 can be used to charge the metal
plate.
16:21 9. Fig. 9.1 shows a circuit with an alternating current (a.c.) supply, a resistor and a diode.
17:45 10. (a) A cloud chamber can be used to detect α (alpha)-particles and β (beta)-particles. Alcohol in the cloud chamber exists as a vapour and condenses on ions produced in the air. This forms visible tracks.
20:05 11. Fig. 11.1 shows a solenoid connected to a battery. On Fig. 11.1, draw the pattern of the magnetic field inside and around the solenoid. Indicate the direction of the magnetic field with an arrow
