9 Funcube-1 is а sаtellite thаt was launched intо оrbit arоund the Earth. It measures 10 cm x 10 cm x 10 cm and has a mass of 0.98 kg. Refer to addendum Figure 9.1 (a) Describe the difference between the orbit of this satellite and the orbit of a comet. (2) (b) In which galaxy would you find the Funcube-1 satellite? (1) (c) Funcube-1 has a mass of 0.98 kg. Calculate the weight of Funcube-1 on Earth. (3) (d) Explain why the moon has a smaller gravitational field strength. Moon g = 1.6 N/kg (2) (e) The rocket carrying Funcube-1 burns fuel to accelerate upwards. As the rocket burns fuel, the energy in its chemical store reduces and the energy in its kinetic store and gravitational store changes. (i) State how the kinetic store of the rocket changes as the rocket burns fuel. (1) (ii) State how the gravitational store of the rocket changes as the rocket burns fuel. (1) (f) The rocket engine stops burning fuel. The rocket continues to go further away from the surface of the Earth. The table gives some statements about the rocket’s energy stores. Statement gravitational store increases gravitational store stays the same gravitational store decreases kinetic store increases kinetic store stays the same kinetic store decreases Write down the two correct statements. (2) (g) Funcube-1 goes into a circular orbit above the surface of the Earth. (i) State the name of the force responsible for keeping Funcube-1 in orbit. (1) (ii) Funcube-1 has an orbital radius of 7100 km and an orbital period of 5800 s. Calculate the orbital speed, in km/s, of Funcube-1. (2) (h) Funcube-1 spins and is heated by the Sun. The diagram shows two coloured metal bars attached to a face of Funcube-1. The surface of one metal bar is dull and black. The surface of the other metal bar is shiny and white. Refer to addendum Figure 9.2 Temperature probes measure the temperature of each metal bar. Use ideas about thermal energy transfer to explain how the temperature of each metal bar changes as Funcube-1 spins. (4) (Total for question 9 = 19 marks)
