8.3.4 please e speed of sound in air depends among others on the air temperature. The following graphshows this relationship.Speed of sound in air versus air temperature350348346344342Speed 340(m.s)338336334332330280 282 284 286288 290 292 294 296 298 300Temperature (kelvin)8.1Which one of temperature or speed is the dependent variable?(18.2The gradient of this graph is equal to 0,6 m-s.K. With how much does the speed,in ms, increase for every 5K increase in temperature?8.3Two experiments are done to verify the Doppler effect. In the first experiment, anobject approaches a stationary observer X at a constant speed of 57,5 m-s'. Theobject is equipped with a siren that emits sound waves at a fixed frequency of1 000 Hz. The motion takes place in still air at a temperature of 295 K.8.3.1Describe what the Doppler effect is.8.3.2What is the speed of sound, in m-s', in air at 295 K?HINT: Use the graph.8.3.3Calculate the frequency measured by observer X.In the second experiment, the object moves away from observer X at thesame constant speed as before. What should the air temperature, inkelvin, be to make it a fair test between the two experiments?8.3.4Consider the three diagrams below. Each one represents the source (with the siren)and observer X. Two of the diagrams are applicable on the above-mentionedexperiments.8.4Diagram 1Diagram 2Diagram 3SourceSourceSource8.3.3Which diagram is applicable to experiment 2?Which diagram is NOT applicable to any of the experiments?Give a reason for your answer.8.3.4xot
