Figure 5 shows a trolley at the top of a slope.

A student gently pushes the trolley until it just starts to roll down the slope.

The student measures the time it takes for the trolley to roll down the slope.

The student repeats this for different values of the angle α.

Figure 6 is a graph of the student’s results.

Use the graph in Figure 6 to find the time the trolley takes to roll down the ramp when the angle α = 45.

time =_........ s

Use the graph in Figure 6 to estimate the time the trolley takes to roll down the ramp when the angle α = 80.

Show your working on the graph.

time =_........ s

The student had a choice of how to measure the time the trolley takes to roll down the ramp.

1. Use a hand‑held stopwatch.

2. Use light gates at the top and bottom of the slope.

The student chose to use the light gates.

Explain why this was the correct choice.

You should refer to the data on the time axis of Figure 6 in your answer.

Figure 7 shows a safety sign on the door of a laboratory where radioactive materials are used.

State one way that radioactivity can be dangerous to humans.

State one piece of equipment that can be used to measure radioactivity.

Alpha (α) radiation and ultraviolet (UV) radiation are ionising radiations.

Give two other ionising radiations.

A sample of a radioactive isotope has a mass of 520 g.

The half‑life of the radioactive isotope is 18 days.

Calculate the mass of the original radioactive isotope remaining after 18 days.

mass after 18 days_........ g

Calculate the mass of the original radioactive isotope remaining after 54 days.

mass after 54 days_........ g

Which statement describes conservation of energy in a closed system?

A student uses the apparatus in Figure 9 to find out which of two materials, sand or sawdust, is the better insulator.

The student also has a kettle to boil water, a thermometer and a stop clock.

Draw a labelled diagram to show how the student should set up the equipment to investigate which material is the better insulator.

Give three factors that the student must control in this investigation.

Expanded polystyrene, used to insulate buildings, has different densities.

Figure 10 shows how the thermal conductivity of expanded polystyrene changes with the density of expanded polystyrene.

energy lost to the surroundings in one second =_........ J

Calculate the efficiency of the kettle.

Use the equation

efficiency =_........

Figure 12 is a speed limit sign from a European motorway.

The speeds shown are in km/h (kilometres per hour).

The sign tells drivers to drive at a slower speed in wet weather.

Explain why it is safer for drivers to drive at a slower speed in wet weather.

Show that a speed of 31 m/s is less than a speed of 130 km/h.

A car is travelling at a speed of 31 m/s.

The car travels 46 m between the driver seeing an emergency and starting to brake.

Calculate the driver’s reaction time.

Give your answer to 2 significant figures.

driver’s reaction time =_........ s
