Fig. 1.1 shows the speed–time graph for a bus journey. The y-axis is speed in m/s (0 to 20), the x-axis is time/s (0 to 80). The bus accelerates from rest, travels at a maximum…

A farmer uses a rope to lift a barrel of fruit from the ground to a platform, as shown in Fig. 2.1. The barrel is lifted a height of 3.2 m. The farmer lifts the barrel of fruit at…

The mass of a glass bottle is 0.18 kg. Calculate the weight of the bottle.

Fig. 4.1 shows a pan on a hotplate. The hotplate heats the pan and the water. The pan has shiny sides, a wooden handle and a copper base. Use your ideas about thermal energy…

Fig. 5.1 shows regions of the electromagnetic spectrum in order of increasing wavelength: gamma rays, X-rays, [unlabelled], visible light, infrared, [unlabelled], radio waves. Two…

A student shines a ray of red light into a rectangular glass block, as shown in Fig. 6.1. At the boundary, the light produces three rays (to be labelled): one continues into the…

Two identical resistors, R1 and R2, are connected to a 24 V battery, as shown in Fig. 7.1 (in series). The value of each resistor is 50 Ω. Calculate the combined resistance of R1…

Fig. 8.1 shows an arrangement for transmitting electricity generated by a power station. The power station generates electricity at 25 kV a.c. A step-up transformer raises this to…

Describe what is meant by alternating current (a.c.).

Fig. 10.1 represents all the particles in a lithium atom (a nucleus with protons and neutrons, surrounded by orbiting electrons; the key labels electron, proton, neutron). State…

Fig. 11.1 represents the Earth in orbit around the Sun, separated by a distance of 1.5 × 10¹¹ m. State the name of the force that keeps the Earth in orbit around the Sun.
