Fig. 1.1 shows a distance–time graph for a cyclist. The distance rises linearly from 0 to about 400 m between time = 0 and time = 100 s, then stays at 400 m to 150 s, then rises…

The mass of a solid metal cylinder is 400 g and its volume is 52 cm³. Calculate the density of the metal. Include the unit.

Fig. 3.1 represents the arrangement and separation of particles in a liquid (each circle represents a particle). In the box in Fig. 3.2, draw at least four circles to show the…

Fig. 4.1 represents a wave on the surface of water (displacement/cm vs time/s), oscillating between +15 cm and −15 cm with a period of 2.0 s. Determine the amplitude of the wave…

Fig. 5.1 shows the main regions of the electromagnetic spectrum in order of increasing frequency: radio waves, ?, infrared, visible light, ultraviolet, ?, gamma rays. Two of the…

Fig. 6.1 shows four wind turbines. Describe how a wind turbine generates electrical power.

Fig. 7.1 shows a ray diagram for an object positioned on the principal axis of a thin converging lens. F1 and F2 are the focal points and C is the centre of the lens. Each small…

Fig. 8.1 shows a solenoid (long coil of wire) connected in a circuit. When the switch is closed, there is a large current in the circuit. Describe an experiment to identify the…

A student investigates an electric circuit. Fig. 9.1 shows the student's circuit (a 6.0 V battery, a variable resistor, an ammeter A and a heater). Describe the purpose of the…

A nucleus of an isotope of actinium contains 89 protons and 136 neutrons. The chemical symbol for actinium is Ac. Complete the nuclide notation for this isotope of actinium (in…

Fig. 11.1 represents the Sun and part of the Solar System, with Mercury and Mars labelled and three other bodies to be named. Complete the labels on Fig. 11.1 by writing on the…
