Solution
(a) Mass is a measure of the amount of matter in an object. It is a fundamental property of the object, which does not change regardless of the location of the object in the universe.
(b) To calculate the density of the plastic from which the cube is made, we need to know the volume of the cube. However, this information is not provided in the question. If it were, we would use the formula density = mass/volume.
(ii) Whether the cube floats or sinks when placed in a container of oil depends on the density of the cube compared to the density of the oil. If the density of the cube is less than the density of the oil, the cube will float. If the density of the cube is greater than the density of the oil, the cube will sink. Without knowing the density of the cube, we cannot definitively answer this question.
(c) The gravitational field strength on the Moon can be calculated using the formula: gravitational field strength = weight/mass. Given that the weight of the cube on the Moon is 0.70 N and the mass of the cube is 0.44 kg, the gravitational field strength on the Moon would be 0.70 N / 0.44 kg = 1.59 N/kg.
