Explain why.

Hailstones are small balls of ice. Hailstones form in clouds and fall to the ground.

Figure 7 shows different-sized hailstones.

A hailstone falls from a cloud and accelerates.

Why does the hailstone accelerate?

Figure 9 shows a balance used to measure the mass of five tomatoes.

What is meant by ‘centre of mass’?

Calculate the mean weight of a tomato in Figure 9.

Determine the spring constant of the spring.

Use the Physics Equations Sheet.

Explain one property of the spring that makes it suitable for use in the balance.

Galaxies contain billions of stars.

Compare the formation and life cycles of stars with a similar mass to the Sun to stars with a much greater mass than the Sun.

The points on Figure 11 represent galaxies that are moving away from the Milky Way.

Each arrow represents the velocity of the galaxy relative to the Milky Way.

Light from all galaxies represented in Figure 11 is red-shifted.

Describe what is meant by red-shift.

Explain how Figure 11 provides evidence for the Big Bang theory.

Sometimes scientists have to change theories about the universe.

Give the reason why.

The National Grid uses transformers to change potential difference (pd).

Figure 12 shows a transformer.

Identify the parts of the transformer labelled in Figure 12.

There is an alternating input pd of 230 V.

Determine the output pd.

Use the Physics Equations Sheet.

The input pd causes an alternating current.

Explain why there is an alternating current in the output when the transformer is connected to a circuit.

Figure 13 shows a large cable supported by two wooden poles. The cable is

connected to an electricity supply.

There is a force on the cable due to the Earth’s magnetic field when the current is in the direction A to B.

Diving bricks sink to the bottom of a swimming pool.

Figure 14 shows a diving brick.

Swimmers practise diving to the bottom of the swimming pool to pick up the diving brick.

Explain why the forces on the brick at the bottom of the pool cause the brick to be stationary.

When the brick from Figure 14 is at the bottom of the pool, the top surface of the brick is 2.50 m below the surface of the water.
