What is the climber’s power? Take g to be 10 N/kg. 78 W 180 W 225 W 250 W 2 / 17 Which of the following pairs of energy resources are most reliable? Nuclear fuel and oil Tidal power and solar power Wave and wind power Solar power and hydroelectricity 3 / 17 What is the useful energy output when 800 J of energy is transferred by a device with an efficiency of 0.8? 100J 160 J 640 J 1000 J 5 / 17 How much energy is stored in the gravitational potential energy store when a 400g ball is kicked up to a height of 20m above the ground? Take ‘g’ to be 10 N/kg. 8 J 80 J 100 J 800 J 6 / 17 Which statement about energy transfer is not correct? The energy store in a stretched elastic band can be transferred to a kinetic store Energy can be transferred by mechanical, electrical and thermal transfers Raising a body above the ground will increases its gravitational potential energy store There will be a net change to the energy store of a closed system when transfers occur 7 / 17 Which of the following statements concerning energy resources is true? Bio-fuel, coal and nuclear fuel are all examples of non-renewable resources The use of nuclear fuel has decreased in the UK since the 1800s. The demand for energy in the World has remained constant since 1900. Energy resources are used mainly for heating, transport and for generating electricity 8 / 17 Which of the following will not lead to an increase in efficiency? Using lubrication in a mechanical process Using thermal insulation in a thermal process Increasing the proportion of the input energy that is dissipated to the surroundings Reducing energy losses through the use of better equipment 9 / 17 Which of the following statements best describes the meaning of ‘specific heat capacity’? The energy required to convert 1kg of ice to 1kg of water The energy required to raise the mass of 1kg of a body by 1oC The energy required to convert 1g of water to 1g of steam The energy given out when a mass of water freezes to become ice 10 / 17 Which of the following pairs of energy resources produce most carbon dioxide when being used ? Coal and nuclear fuel Oil and Coal Geothermal and tidal power Nuclear fuel and hydroelectricity 11 / 17 What will be the main changes in energy stores when a car, moving horizontally on a flat road, is brought to rest by applying the brakes? Chemical store and kinetic store decrease, gravitational potential store increases Thermal store decreases, kinetic and chemical stores increase Chemical, gravitational and kinetic store decrease Kinetic store decreases and thermal store increases. 12 / 17 Aluminium has a specific heat capacity of 900 J/kgoC and water has a specific heat capacity of 4200 J/kgoC. Based on these figures, which of the following statements is true? 1kg of aluminium will take much longer to change its temperature than water Water will turn to steam more easily than aluminium metal will melt. Aluminium is much more suitable for use in car radiators than water 1kg of water needs to receive much more energy than 1kg of aluminium to change its temperature by 1oC. 13 / 17 Which of the following statements is true for the bungee jumper? Before he jumps, his gravitational potential energy is at its lowest value When he jumps, the bungee cord will immediately extend to its maximum length His gravitational potential energy store will be transferred to kinetic and elastic potential stores As he falls, the total gravitational potential and kinetic energy stores of the system will decrease 14 / 17 A microwave oven transfers 600,000J of energy in 10 minutes. What is the power rating of the microwave oven? 750 W 1000 W 1200 W 6,000,000 W 15 / 17 How much energy is stored as a kinetic store when a toy car of mass 500g moves at 3 m/s? 2.25 J 4.5 J 1500 J 2250 J 16 / 17 A mass of 60kg of water is heated from 20oC to 100oC. How much energy is required to do this? Water has a specific heat capacity of 4200 J/kgoC. 9450 J 378,000 J 15,120,000 J 20,160,000 J 17 / 17 How much energy is stored as elastic potential energy when a spring, of spring constant 50N/m, is stretched by 0.4m? 0.5 J 1J 4 J 10 J Your score is The average score is 37% LinkedIn Facebook Twitter VKontakte 0% Restart quiz Was this article helpful?YesNo
