Oil of density 0.80 g/cm³ is poured gently onto the surface of water of density 1.0 g/cm³. The oil and the water do not mix. Describe and explain the final position of the oil…

Fig. 2.1 is a graph that shows how the extension of a spring varies with the load suspended from it. It is a straight line through the origin reaching an extension of 4.0 cm at a…

Fig. 3.1 shows a boy throwing a ball at an object in a fairground. The ball has a mass of 190 g and travels horizontally with a constant speed of 6.9 m/s. Calculate the momentum…

The lowest possible temperature is zero kelvin (0 K). State the name of this lowest possible temperature.

Fig. 5.1 is a scale diagram of wavefronts of red light approaching a gap in a barrier (wavelength and wavefronts marked). On Fig. 5.1, draw three wavefronts after the wave has…

On Fig. 6.1 (a blank set of axes), sketch the current–voltage graph of a filament lamp and explain its shape.

Fig. 7.1 shows the electric field pattern around point X (radial field lines), with a point Y nearby. On Fig. 7.1, draw an arrow to indicate the direction of the force on a…

Fig. 8.1 shows the single turn coil of a simple direct current (d.c.) motor placed between magnetic poles S (left) and N (right), with current flowing in the coil and an observer…

For each application of radioactive isotopes, state and explain which type of radioactive emission is suitable and suggest an appropriate half-life for the isotope. household…

State what is represented in space physics by the symbol H0.
