The fuel cost for wind turbines is very high.  \n0  1 . 5 A wind turbine has an average power output of 0.60 MW.  \nA coal-fired power station has a continuous power output of 1500 MW.  \nCalculate how many wind turbines would be needed to generate the same power output as one coal-fired power station.  \n[2 marks]  \nNumber of wind turbines =    \n0  1 . 6 It is important that scientists develop new energy resources.  \nChoose one reason why.  \n[1 mark]  \nTick one box.  \nAll energy resources are running out.  \nAll energy resources are used to generate electricity.  \nMost energy resources have negative environmental effects.  \nTurn over for the next question  \n0  2 Figure 2 shows a student before and after a bungee jump.  \nThe bungee cord has an unstretched length of 20 m.  \nFigure 2  \n0  2 . 1 For safety reasons, it is important that the bungee cord used is appropriate for the student’s weight.  \nGive two reasons why.  \n[2 marks]  \n1  \n0  2 . 2 The student jumps off the bridge.  \nComplete the sentences to describe the energy transfers.  \nUse answers from the box.  \n[3 marks]  \nelastic potential gravitational potential kinetic sound thermal  \nBefore the student jumps from the bridge he has a store of  \n  energy.  \nWhen he is falling, the student’s store of   energy increases. When the bungee cord is stretched, the cord stores energy as  \n  energy.  \n0  2 . 3 At the lowest point in the jump when the student is stationary, the extension of the bungee cord is 35 metres.  \nThe bungee cord behaves like a spring with a spring constant of 40 N/m.  \nCalculate the energy stored in the stretched bungee cord.  \nUse the correct equation from the Physics Equations Sheet.  \n[2 ","cbCaie1QEsxCOxzE","https://ap.wps.com/l/cbCaie1QEsxCOxzE","pdf",3226079,1,34,"English","en",105,"# Energy resources\n## Wind turbine questions\n## National Grid question\n## Comparing power outputs\n## Scientist reasons for new energy resources\n# Bungee jump energy transfers\n## Safety and appropriate bungee cord reasons\n## Energy transfers completion\n## Energy stored in stretched cord\n# Electrical circuits\n## Direct current definition\n## Potential difference across a battery\n## Power output of a battery\n# Change of state of stearic acid\n## Advantages of apparatus\n## Type of error from readings\n## Temperature decrease from graph","[{\"question\":\"What equipment is required to complete this specimen paper?\",\"answer\":\"A ruler and a calculator are required, along with the Physics Equation Sheet enclosed with the paper.\"},{\"question\":\"How is the National Grid described in the questions?\",\"answer\":\"Students must select the correct option describing the National Grid as a system of cables and pylons.\"},{\"question\":\"What is asked about the wind turbine and power generation over one day?\",\"answer\":\"Students answer how many hours the wind turbine generated no electricity and compare wind turbine output with coal-fired power station output to calculate the number of turbines needed.\"}]","GCSE Physics Foundation Tier Paper 1F -
