FORMULAE You may find the following formulae useful. energy transferred = current×voltage×time E = I×V×t frequency = 1 time period f = 1 T power = work done time taken P = Wt power = en... ergy transferred time taken P = W t orbital speed = 2 orbital radius time period π × v = 2 r π T × × (final speed)2 = (initial speed)2 + (2×acceleration×distance moved) v2 = u2 + (2×a×s) pressure×volume = constant p1×V1 = p2×V2 pressure temperature = constant p T p T 1 1 2 2 = Where necessary, assume the acceleration of free fall, g = 10 m/s2.*P68387A0332* Turn over 3 BLANK PAGE4 *P68387A0432* Answer ALL questions. 1 (a) The boxes give some situations and some energy stores. Draw one straight line from each situation to the energy store that decreases for that situation. The first one has been done for you. (4) Situation Energy store elastic kinetic thermal nuclear gravitational a beaker of water cooling down a car moving horizontally and slowing down a ball falling towards the ground a nucleus splitting due to fission a stretched rubber band decreasing in length*P68387A0532* Turn over 5 (b) Energy is transferred when a filament lamp is connected to a battery. (i) Which method of energy transfer takes place between the battery and the lamp? (1) A electrical B heating C mechanical D radiation (ii) Which method of energy transfer takes place between the lamp and the surroundings? (1) A electrical B light radiation C mechanical D sound radiation (Total for Question 1 = 6 marks)6 *P68387A0632* 2 The diagram shows the apparatus used to demonstrate the existence of electromagnetic radiation just beyond the visible spectrum. Electromagnetic radiation from the Sun passes through a slit and a prism. The electromagnetic radiation refracts through the prism onto the screen. Five thermometers are placed in front of the screen. electromagnetic radiation from Sun slit prism T S R Q P screen not to scale thermometers (a) Complete the table to show the missing parts of the electromagnetic spectrum. (3) Thermometer Part of electromagnetic spectrum P Q red light R S violet light T*P68387A0732* Turn over 7 (b) Suggest why the lower part of each thermometer should be painted black.
