USP [2] Write down the equation which links density (o), mass (m) and volume (V). [1 mark] [3] The mass of seawater passing through the tidal turbine each second is 824 000 kg. The density of seawater is 1030 kg/m°. Calculate the volume of seawater passing through the tidal turbine each second. [3 marks] Volume = m? Question 1 continues on the next page Turn over > IB/G/Jun25/8463/1H The speed of the tide or the speed of the wind past a turbine is called the ‘flow speed’. Figure 2 shows how the power output of a tidal turbine compares with a wind turbine for different flow speeds.

[3] One source of error in the experiment was energy loss to the surroundings. Suggest one change to the apparatus to reduce energy loss to the surroundings. [1 mark] {4] The student's value for the specific heat capacity of water was 4410 J/kg °C. The actual value for the specific heat capacity of water is 4200 J/kg °C. Calculate the percentage difference between the student's value and the actual value.

[1 mark] Mass of carbon dioxide = kg [3] At one distance, the amount of carbon dioxide emitted by both cars is the same. What is this distance? [1 mark] Distance = km IB/G/Jun25/8463/1H Donot write outside the ‘box 13 (ofa) [4] [of] [5] Some energy resources emit carbon dioxide when used to generate electricity. The battery-powered electric car does not emit carbon dioxide as it is driven. Explain why more carbon dioxide is produced as the distance travelled by the electric car increases. [2 marks] Which two of the following energy resources do not emit carbon dioxide when used to generate electricity? [2 marks] Tick (“) two boxes. Biofuel Nuclear Oil Solar Wood Turn over > IB/G/Jun25/8463/1H Donot write outside the ‘box 15 Donot write outside the [3] The fusion reaction releases large amounts of energy. box The fusion reaction takes place in a reactor. Explain why the walls of the reactor should be made from a material with a very high specific heat capacity. [2 marks] [4] Nuclear fusion is safer than nuclear fission. Nuclear fission can lead to an uncontrolled chain reaction. Give one consequence of an uncontrolled chain reaction.

Figure 8 Heating pad [1] The heating pad has a mass of 0.20 kg. When the hand warmer was switched on, the energy transferred to the heating pad was 8000 J. specific heat capacity of heating pad = 1600 J/kg °C Calculate the temperature increase of the heating pad. Use the Physics Equations Sheet. [3 marks] Temperature increase = °C IB/G/Jun25/8463/1H 18 Donot write outside the [3] The circuit inside the hand warmer can be connected to a mobile phone to recharge box the mobile phone. Figure 9 shows the circuit diagram when the hand warmer is connected to a mobile phone. The heating pad of the hand warmer is represented by the resistor symbol. Figure 9 Mobile — oS phone Explain how closing both switches S; and S:2 affects the power output of the battery compared with only closing switch S:. [3 marks] IB/G/Jun25/8463/1H 19 Donot write outside the Some atoms emit radiation. box Why do scientists sometimes change the model used to describe the structure of the atom? [1 mark] Tick (W) one box. Existing models use ideas that are old fashioned. New evidence is discovered that existing models cannot explain. Scientists need to develop new models every 100 years. The public do not understand old models so new ones are created. [o| 7] [2] When radioactivity was discovered, the dangers of radiation were not known. Some scientists were irradiated and contaminated while working with the radioactive materials. Describe the difference between irradiation and radioactive contamination.
