A weight of 3.0 N is hung from the spring.
What is the extension of the spring?

The diagram shows a plank balanced on a pivot. Three forces $F$, $P$ and $Q$ act on the plank, as shown.

The force $F$ is increased, but continues to act at the same distance from the pivot. The plank is no longer balanced.
Which change could make the plank balance again?

Which energy transfer takes place when petrol is burned?

The box contains the names of eight different energy resources.

What is the instrument called?

Smoke particles in air are illuminated by a beam of light. The particles are viewed through a microscope. They are seen to move in a random zig-zag way. What causes this movement?

When a liquid evaporates, some of its molecules escape from the surface and the temperature of the liquid changes.
Which row describes the escaping molecules and the change in temperature of the liquid?
[Table_1]

A piece of melting ice at 0°C and a beaker of boiling water are both in a laboratory. The laboratory is at 20°C.

What is happening to the temperature of the melting ice and what is happening to the temperature of the boiling water?

Which statement about infra-red radiation is correct?

A pan is made for heating water on a stove.

From which type of materials should the pan and its handle be made?

A toy boat floats on water in a tank. The boat is initially stationary.
A stone is thrown into the tank, which causes a transverse water wave to move across the surface.
The diagram shows the view from above the tank.
[Image_1: Diagram of a stone and toy boat in a tank with wavefronts labeled]
How does the boat behave as the wave passes it?

Below are four statements about the diffraction of a wave on the surface of water.
Which statement is correct?

A child wears a T-shirt with the letter 'F' written on it. The child stands in front of a vertical plane mirror. What does the child see?

When white light passes through a glass prism, it disperses as shown in the diagram .
Which row compares the refraction of violet light with the refraction of red light at the faces 1 and 2 of the prism?

Radiation from which part of the electromagnetic spectrum is used in the remote controller for a television?

A girl notices that, when she shouts into a cave, she hears an echo. Which wave property causes the echo?

The diagrams represent the displacement in four different sound waves. All the diagrams are drawn to the same scale. Which diagram represents the sound with the highest pitch?

In two separate experiments, a magnet is brought near to an unmagnetised iron bar. This causes the bar to become magnetised.



Which magnetic pole is induced at X and at Y?

A polythene rod is rubbed with a cloth. The rod becomes positively charged because of the movement of charged particles.
Which row gives the name of these charged particles, and the direction in which they move?

The diagram shows a lamp in a circuit.
Which change to the circuit would increase the current in the lamp?

An ammeter and an $18\,\Omega$ resistor are connected in series with a battery. The reading on the ammeter is $0.50\,\text{A}$.

What is the electromotive force (e.m.f.) of the battery?

A source of constant electromotive force (e.m.f.) is connected across a thermistor.
There is an electric current in the thermistor. The temperature of the thermistor is reduced.

Which row shows what happens to the resistance of the thermistor and what happens to the current?
[Table_1]

The diagram shows a circuit containing a battery, a resistor with high resistance, a switch, and a lamp.
Initially, the switch is open. What happens to the lamp when the switch is closed?

The diagram shows a circuit containing two identical lamps and three ammeters.
The current in ammeter 1 is 0.30 A.
Which row gives possible values for the currents in ammeters 2 and 3? [Table_1]

Two electrical appliances are connected to the mains supply.
The cable connected to one appliance includes an earth wire.
The cable connected to the second appliance does not need an earth wire.
What is a reason for this difference?
