AQA GCSE Physics paper 1 Questions and Answers! It is unlikely that all of the electricity that the UK needs can be generated by solar power systems. Explain why - ANSWERA really large area of land would need to be covered with solar cells due to the low useful power output of the solar cells Suggest two advantages of using this method to charge electric cars compared with plugging them into the mains electricity supply. - ANSWERrecharging is a continuous process fewer cells needed in the car more cars can be charged at the same time When electric cars are not being driven, energy stored in their batteries could be used to meet sudden peaks in electricity demand. Suggest how. - ANSWERwhen cars are plugged in the energy from car batteries could be transferred back to the National Grid At the bottom of the slide, all riders and their sleds have approximately the same speed. Explain why. - ANSWER1⁄2 mv2 = mgh masses cancel on both sides of the equation (final) speed only depends on vertical height (and gravitational field strength) variations will be due to air resistance/friction When the kettle was switched on the temperature of the water did not immediately
