Question 1 Not yet answered Marked out of 12.00 Flag question Sustainability is a complex issue that involves weighing up options. Given the following choices, and considering any/all of the three dimensions of sustainability, provide a potential argument i) in favour of the choices. (1 mark) ii) against the choice (1 mark) iii) What information would you require to make a final decision? (2 marks) For example, let's say the option is: buy a new dishwasher or keep washing dishes by hand. i) My argument for buying the dishwasher is that they use less water. ii) An argument for washing by hand is that you don't have to produce a dishwasher. iii) To make your decision you would need to know: how much water you use now, how much water you would save, and the environmental cost of producing a dishwasher, the environmental cost of operating it using electricity, and the lifespan of the dishwasher. The choices to consider are: a) Repurposing agricultural land for biofuel production b) Building a solar farm instead of a wind farm c) Closing a coal-fired power plant Font family Font size Paragraph HB ai) Potential argument for: ii) Potential argument against: iii) Extra information you need to make a decision: b) Potential argument for: ii) Potential argument against: iii) Extra information you need to make a decision: Question 2 Not yet answered Marked out of 6.00 Assess the accuracy of the following statements. Give a reason for your answer. (2 marks each. O if no reason is given!) a)"If you run at a constant speed, your acceleration is zero. Since F = ma, the force you use must be zero. Since W = Fd, you are doing no work. So, running does not use any energy." b) "When I make ice in my freezer the freezer transfers cold energy to the water, turning it into ice." c) "The temperature of a cup of water describes a macroscopic property and cannot tell me anything about a particular water molecule's kinetic energy."
