13. In a vacuum, which wave CANNOT travel?
14. What net force is needed to accelerate a 2 kg object at 3 m/s2?
15. A student argues that polarised sunglasses prove light behaves as a particle. Which response best evaluates this claim?
16. Compare and contrast transverse and longitudinal waves. In your answer, describe how particles move in each type, include labelled diagrams, and give two examples of each. 4 MARKS
17. Explain how electromagnetic waves are used in one communication technology and one medical technology in Australia. Include the type of EM wave used in each and how it works. 4 MARKS
18. A 1000 kg car is pushed with a force of 2000 N. There is 500 N of friction opposing the motion. Calculate the net force acting on the car and then calculate its acceleration. Show your working. 4 MARKS
19. Describe an investigation you could carry out to determine the relationship between the tension in a string and the speed of a wave on it. Include the independent and dependent variables, variables to control, a brief method, and expected results. 4 MARKS
20. Synthesise your understanding of waves and motion by explaining how both concepts are involved when a surfer catches and rides a wave at an Australian beach. Refer to at least two physics principles from this unit. 4 MARKS
