29 Here are two cubes, A and B. Cube A has a mass of 81 g. Cube B has a mass of 128g. Work out the density of cube A: the density of cube B Give your answer in the form a:b where a and b are integers.

True or false? Magnetic field lines always point from south poles to north poles.

square A vertical rope PQ has its end Q attached to the top of a small lift cage. The lift cage has mass 40 kg and carries a block of mass 10kg, as shown in Figure 1. The lift cage is raised vertically by moving the end P of the rope vertically upwards with constant acceleration 0.2ms^-2 The rope is modelled as being light and inextensible and air resistance is ignored. Using the model, (a) find the tension in the rope PQ (b) find the magnitude of the force exerted on the block by the lift cage.
