Answer ALL questions. Some questions must be answered with a cross in a box . If you change your mind about an answer, put a line through the box and then mark your new answer with a cross . 1 (a) ... The table lists four methods of generating electricity and four energy stores. Energy store Method of generating electricity Thermal Gravitational potential Kinetic Chemical geothermal power station hydroelectric power station petrol generator wind turbine The energy store of the initial energy resource decreases when electricity is being generated. (i) Complete the table by placing one tick () in each row to show which energy store decreases. (4) (ii) State which method of generating electricity in the table does not use a renewable energy resource.

Before the ball is hit, it is moving to the left with a momentum of 4.2 kg m/s. The bat is in contact with the ball for 0.012 s. After the ball is hit, it moves to the right with a momentum of 6.7 kg m/s. Calculate the mean force the bat exerts on the ball and state the direction of the force. (3) mean force = ............................................... N direction ............................................... (ii) State the magnitude and direction of the mean force the ball exerts on the bat. (1) magnitude of mean force = ...............................................

This protective equipment reduces the risk of injury to the player if they are struck by the cricket ball. Explain how this protective equipment reduces the risk of injury to the player. Use ideas about momentum in your answer.
