A vernier scale is used with a ruler to measure extensions of a wire.
The diagrams show the position of the vernier scale against the ruler before and after a mass is suspended from the end of the wire.
What is the extension caused by the mass?
0.53 cm
0.13 cm
0.03 cm
1.00 cm
The speed-time graph is for a car initially at rest.
The car starts to move.
Which correctly describes the car's subsequent motion?
moving with non-uniform acceleration and then moving with uniform acceleration
moving with uniform speed and then moving with uniform acceleration
moving with uniform speed and then moving with non-uniform acceleration
moving with uniform acceleration and then moving with non-uniform acceleration

The speed-time graph is for a car initially at rest.
The car starts to move.
Which correctly describes the car's subsequent motion?
A car is accelerating along a road in the direction shown. The wheel shown is connected to the engine.
In which direction is the force of friction exerted by the road on the car tyre?
An object that has a mass of 15 kg on the Earth is taken to the Moon.
The gravitational field strength on the Earth is 10 N/kg and on the Moon is 1.6 N/kg.
What are the mass and the weight of the object on the Moon?
A ball is held over the edge of a balcony. The ball is released and falls on to a concrete path below, before bouncing back up.
Which row shows the correct order of the energy transformations?
A car, of mass 1000 kg, is slowly going down a steep hill. The brakes fail and the driver uses a horizontal sand-filled safety road to stop the car.
The car enters the sand at a speed of 10 m/s and is subjected to a stopping force of 2500 N.
How far does the car travel before coming to rest?
Which form of energy, that molecules have, is related io temperature?
Boiling and evaporation are different processes.
Which statement is not correct?
What is meant by the term wavefront?
The diagram shows how displacement varies with time as a wave passes a fixed point.
What is the frequency of this wave?
The diagram shows two rays of light from an object.
The object is 10 cm in front of the lens.
In this example, what is the focal length of the lens and the type of image formed?
When sections of a large metal pipe have been welded together, they are checked to discover whether there are any cracks in the joints.
Which component of the electromagnetic spectrum is used for this purpose?
What is the correct order for the speed of sound in air, steel and water?
A girl, standing 165 m in front of a tall building, fires a starting pistol.
A boy, standing 350 m from the girl, hears two bangs 1 s apart.
Using this information, what is the speed of sound in air?
The graph shows the results of an experiment to determine the resistance of a wire.
What is the resistance of the wire?
A wire of length 0.50 m and a cross-sectional area of 1.0 x 10-6 m2 has a resistance of 0.75 Ω.
Another wire of the same material has a length of 2.0 m and a cross-sectional area of 0.5 x 10-6 m2.
What is the resistance of the longer wire?
In the circuit shown, the battery lights up all four lamps.
When the filament of one of the lamps melts, the other three lamps stay on.
Which lamp filament melts?
An electric heater takes a current of 4 A from a 250 V supply when operating normally.
How long would it take the heater to convert 400 000 J of electrical energy?
The diagram shows how a steel bar can be magnetised.
Which statement describes how the steel bar can be demagnitised?
A copper wire carrying a current is held between the poles of a magnet.
The current in the wire can be reversed. The poles of the magnet can be changed over.
In how many of the four directions shown can a force act on the wire?
