The driver applies the force shown in Figure 8. The force produces a moment about the pivot. How could the driver increase the moment about the pivot without increasing the size of the force? Infrared waves are transverse waves. In a transverse wave, the direction of oscillation is to the direction of energy transfer by the wave. A student investigated how the colour of a surface affects the rate at which the surface emits infrared radiation. Figure 1 shows some of the equipment used. The student wrote the following hypothesis: ‘The black-coloured flask will emit more infrared radiation than the silver-coloured flask during 10 minutes of cooling.’ Describe a method to test this hypothesis. When will the flasks emit infrared radiation at the greatest rate? Give a reason for your answer. [2 marks] Tick () one box. During the 1st minute During the 5th minute During the 9th minute Figure 2 shows one of the cubes. The cube is filled with water. The weight of the water exerts a pressure on the bottom of the cube. Which equation correctly links area, force and pressure? The water pressure at the bottom of the cube is 1500 Pa. Calculate the force of the water on the bottom of the cube. Figure 3 shows the route an aeroplane takes as it travels from an airport terminal to the runway. Figure 3 has been drawn to scale.
