A student measures the diameter of some identical steel balls. Fig. 1.1 shows the arrangement she uses: a row of touching steel balls held between point A and a wooden block at…

Fig. 2.1 shows the speed–time graph for a cyclist (speed/(m/s) 0–14 vs time/s 0–50). The sections ST, TW, WX, XY and YZ indicate stages of the cyclist's journey. State one section…

A student has a battery-powered torch (Fig. 3.1). Fig. 3.2 shows the energy transfers when the torch is switched on; the diagram is incomplete. An energy store of 100 J transfers…

A student has a block of solid metal at room temperature. Describe the arrangement, separation and motion of the particles in the solid metal.

An observer stands at P and looks into a rock quarry. A small explosion takes place at X in the quarry. Fig. 5.1 shows the situation (P at top-left, the explosion at X, solid rock…

Fig. 6.1 shows light waves (wavefronts) passing from air into a glass block. State the name of the process shown in Fig. 6.1 as the wavefronts enter the glass block.

A student uses a permanent magnet to lift some unmagnetised nails. Some of the nails are made of iron and some are made of steel. Fig. 7.1 shows the magnet (N pole and S pole)…

A student uses the circuit in Fig. 8.1 to measure the resistance of the heater in the circuit (with a variable resistor and a heater). The symbols for the two meters in Fig. 8.1…

A student has a desktop computer that connects to the 240 V a.c. mains electrical supply (Fig. 9.1). The desktop computer has an on-off switch in one of the wires that connect it…

Iodine-131 is a radioactive isotope of the element iodine. Fig. 10.1 shows the nuclide notation for a nucleus of iodine-131 (mass number 131, proton number 53, symbol I).…

Fig. 11.1 shows the Sun and the four innermost planets, A, B, C, and D, of the Solar System (in order of increasing distance from the Sun). In Table 11.1, write the names of the…
