represents the four planets nearest to the Sun. Sun Earth Venus (not to scale) Two of the planets in are not labelled. On each dotted line, write the name of the planet. The distance of Venus from the Sun is 1.1 × 1011 m. The speed of light is 3.0 × 108 m / s. Calculate the time it takes light to travel from the Sun to Venus. time taken = s The mass of the Earth is greater than the mass of Venus. The gravitational field strength on the surface of the Earth is 9.8 N / kg. Suggest a value for the gravitational field strength on the surface of Venus. Give a reason for your answer. gravitational field strength on surface of Venus = N / kg reason

shows the Sun as the central dot and the planets Saturn, Jupiter and Earth labelled S0, J0 and E0. The planets orbit the Sun anticlockwise. From the Earth’s orbit, the planets appear aligned. E0 J0 S0 (not to scale) Assume that Saturn takes 30 years to orbit the Sun and that Jupiter takes 12 years to orbit the Sun. On , mark the positions of Saturn and Jupiter 5.0 years after the original positions shown. Label these positions S1 and J1. Show your working. On , mark the positions of Saturn and Jupiter 20 years after the original positions shown in . Label these positions S2 and J2. State what is observed from the Earth’s orbit after 20 years. Choose two words from the list to describe each planet. gaseous large rocky small Jupiter Earth The average density of Jupiter is much less than that of the Earth. The gravitational field strength at the surface of Jupiter is greater than that at the surface of the Earth. Explain how these differences in density and in gravitational field strength are consistent with your answers to . density gravitational field strength The average density of Jupiter is 1300 kg / m3 and its volume is 1.4 × 1015 km3. Calculate the mass of Jupiter. mass =
