A parcel delivery van leaves its overnight parking space and covers a distance of 100 km in the morning and a further 75 km in the afternoon.
It then returns and is left in the same parking space overnight.
What is the magnitude of the displacement of the van at the end of the journey?
The graph shows a velocity-time graph for a car journey.
Which statment is correct?

The frictional force due to the air on a moving object gets four times larger when its speed doubles.
The object has a mass of 4.0 kg and falls through the air at 6.0 m/s. The object accelerates at 9.0 m/s^2. The gravitational field strength is 10 m/s^2.
What is the frictional force on the body when it is moving at 12 m/s?
The density of an oil is 800 kg/m^3, the density of water is 1000 kg/m^3 and the density of mercury is 13600 kg/m^3.
A solid cube has a side length of 40 mm and a mass of 80 g.
Which statement is correct?
An object is placed on a uniform plank between two supports, X and Y.
The object weighs 400 N and the plank weighs 100 N.
What is the upward force exerted by support X?

On Earth, the gravitational field strength is 10 N/kg.
A block of wood has a mass of 2.0 kg and has dimensions of 50 cm x 10 cm x 10 cm.
The block is placed on a table so that the pressure it exerts on the table is the largest.
What is this pressure?

Water in a tank is heated. No water enters or leaves the tank.
Which statement explains why water at the bottom of the tank stays cold for some time?

A beaker of water is heated from room temperature.
After a short time, small bubbles appear at the bottom of the beaker and rise slowly to the surface.
After a longer time, large bubbles are formed which rise rapidly to the surface.
Which statement is correct?
The frequency of a wave is increased.
Which other quantity of the wave must change?
A radiowave travels at a speed of 3.0 x 10^8 m/s.
It has a frequency of 150 MHz.
What is its wavelength?
The diagram shows a right-angled prism being used to turn a ray of light through 90°.
What is the critical angle for the light in the prism?

The diagram shows an object and a thin converging lens of focal length f. The object distance from the centre of the lens is greater than 2f.
Which statement is correct?

A fishing boat uses echo location to find fish below the boat. The boat receives two echoes: one from a shoal of fish and one from the sea floor.
The diagram shows the time taken for both echoes to be received after the sound was emitted.
The speed of sound in seawater is 1500 m/s.
What is the depth of the shoal of fish?

Which statement about electric field lines caused by two isolated point charges is not correct?
A resistor and a motor are connected in series and the combination is then connected to a 12 V battery.
The resistance of the motor is 1.0 Ω and the resistor prevents a current of more than 4.0 A in the motor.
What is the minimum value of the resistor?
A lamp, a resistor and a motor are connected in parallel. The combination is then connected to a battery.
Which statement is correct?
The diagrams show a fuse, a lamp and a heater.
Which diagram shows the fuse in the correct place?
A magnetic compass is above a copper wire, as shown.
The wire carries a large current. The compass needle points up (north) when the current in the wire is from right to left, as shown.
Which way does the compass needle point when the direction of the current is reversed?
