AQA GCSE Trilogy Physics Paper 2 Foundation June 2022 question paper 8464/P/2F

There are different types of electromagnetic waves.

What do all electromagnetic waves transfer? Tick (✓) one box.

Complete the sentence. Choose answers from the box.

Different types of electromagnetic waves have a different

Figure 1 shows the electromagnetic spectrum.

Give the names of parts A and B of the electromagnetic spectrum.

Different types of electromagnetic waves have different uses. Draw one line from each type of electromagnetic wave to its use. Type of electromagnetic Use wave

A student investigated how the colour of a surface affects the power of the infrared radiation emitted by the surface. Figure 2 shows the equipment used.

The infrared detector measures the power of the infrared radiation emitted by

the flasks.

The student poured hot water into each flask. What should the student do to reduce the risk of burning herself with the hot water?

Describe how the student should use the equipment in Figure 2 to compare the power of the infrared radiation emitted by each surface.

A student investigated how the power of the infrared radiation emitted from a flask

changed with time. Table 1 shows the results.

Describe the pattern shown by the data in Table 1.

What is the most likely value for the power of the infrared radiation emitted after 480 seconds? Use Table 1. Tick (✓) one box.

A Leslie Cube is used to demonstrate that different surfaces emit different amounts of

infrared radiation. Figure 3 shows an infrared detector and a Leslie Cube filled with hot water.

Give one advantage of using a Leslie Cube rather than the equipment in Figure 2 on page 4.

The teacher improved the demonstration by using four infrared detectors connected to a data logger and computer. Each detector was pointed at a different surface of the Leslie Cube. The distance between the surface and the detector was the same in each case. Give two reasons why this improved the demonstration.

Figure 4 shows an apple hanging from a tree. The X marks the centre of mass of the apple.

Draw an arrow on Figure 4 to represent the weight of the apple.

The apple has a mass of 0.150 kg gravitational field strength = 9.8 N/kg Calculate the weight of the apple. Use the equation: weight = mass × gravitational field strength

The apple in Figure 4 is stationary. Why is the apple stationary? Tick (✓) one box.

When the apple is ripe it falls from the tree and accelerates towards the ground.

Why does the apple accelerate? Tick (✓) one box.

The acceleration of the apple is 9.8 m/s² The velocity of the apple changes from 0 to 4.9 m/s Calculate the time taken for the apple to fall to the ground. Use the equation:

Figure 5 shows a compass.

Why does the compass always point in the same direction when it is not near a magnet? Tick (✓) one box.

What material could the needle of the compass be made from? Tick (✓) one box.

Figure 6 shows a coil of wire.

There is a current in the coil. The circles show the position of four compasses.

Which statement describes the magnetic field around the coil? Tick (✓) one box.

Draw one arrow in each circle on Figure 6 to show the direction of the magnetic field at that point.

Give two ways the magnetic field around the coil could be made stronger.

The stopping distance of a car is the sum of the thinking distance and the braking distance.

Which factors affect the thinking distance? Tick (✓) two boxes.

Explain why a person should not drink alcohol and then drive.

The Highway Code gives information on how thinking distance depends on the speed

of a car. Figure 7 shows the information as a graph.

What is the speed of a car if the thinking distance is 16 m?

Describe the relationship between speed and thinking distance.

The Highway Code assumes the driver’s reaction time is 0.70 seconds. Draw a line on Figure 7 to show the relationship for a driver with a reaction time of 1.4 seconds.

A car accelerates at 5.0 m/s² over a distance of 45 m initial velocity of the car = 0 m/s Calculate the final velocity of the car. Use the Physics Equations Sheet. Give your answer to 2 significant figures.

Figure 8 shows a longitudinal wave.

What do the labels A and B on Figure 8 represent? Choose answers from the box.

The wave shown in Figure 8 has a frequency of 4.0 kHz Calculate the period of the wave. Use the Physics Equations Sheet. Give the unit.

Sound waves are longitudinal. Figure 9 shows how the speed of sound varies with the temperature of the air.

Use the Physics Equations Sheet to answer questions 06.3 and 06.4.

Write down the equation that links frequency (f), wavelength (λ) and wave speed (v).

A sound wave with a frequency of 300 Hz travels through the air. The air has a temperature of 28.0 °C

Determine the wavelength of the sound wave. Use Figure 9.

Figure 10 shows competitors in the wheelchair race at the London Marathon. The distance of the London Marathon is 42 000 m

Use the Physics Equations Sheet to answer questions 07.1 and 07.2.

Write down the equation that links distance (s), force (F) and work done (W).

During the race competitors work against air resistance. The work done against air resistance by the winner of the race was 3 360 000 J Calculate the average air resistance acting on the winner of the race.

Use the Physics Equations Sheet to answer questions 07.3 and 07.4.

Which equation links distance travelled, speed and time? Tick (✓) one box.

The distance of the London Marathon is 42 000 m The winning time for the race was 5600 seconds. Calculate the average speed of the winner of the race.

Explain why the speed of a competitor changes during the race.
