A ball of mass 130 g is launched from the ground at an initial velocity of 14 m/s vertically upwards. It decelerates until it is at rest momentarily at a height h above the…

Fig. 2.1 shows solar-powered traffic warning lights, with a solar cell and lights. The energy from the solar cell is stored in a battery. Name the energy store in the battery.

Fig. 3.1 shows two children balanced on a seesaw (a length of wood rotating about a central pivot). Child A (weight 450 N) sits 1.60 m from the pivot; child B (weight 900 N) sits…

Fig. 4.1 shows a stainless-steel saucepan containing water being heated on an electric cooker. State what happens to the water particles as the water temperature increases.

Fig. 5.1 shows two containers, each filled with hot water: one metal and one non-metal. The outer surface of the metal container is hot. Explain how electrons transfer thermal…

Fig. 6.1 shows a thin converging lens used to produce a magnified image of an object AB. The object AB stands just inside the focal point F1, with F2 on the far side; the…

Fig. 7.1 shows two charged metal plates: a positively charged plate on top and a negatively charged plate below, with X at the centre of the space between them. On Fig. 7.1, draw…

Fig. 8.1 shows images produced during two different medical scanning procedures: an ultrasound scan of a fetus and an X-ray scan of a hand. Define ultrasound.

Fig. 9.1 shows a mobile phone being charged on a wireless charging plate (a primary coil in the charging plate and a secondary coil in the mobile phone). When the charging plate…

Leaks in underground water pipes are detected using radioactive tracers. Fig. 10.1 shows a radiation detector above a water pipe, with a counter reading 382 above a leak. Before…

A galaxy is approximately 1.2 × 10²⁶ m from the Earth. Scientists observe light from the distant galaxy. The wavelength of the observed light is longer than the wavelength of the…
