- The student took four pressure readings for each temperature. Table 1 shows the pressure readings when the temperature was 50.0^circ C Table 1 Calculate the uncertainty in the mean pressure. [2 ma
- 2. Questions 2a, 2b and 2c refer to a 0.250 kg pendulum. (a) What length of the pendulum is needed to oscillate at the same frequency as the object in question 1? Show your work [2 marks] (b) What is the restoring force on the pendulum at an angle of 6.24c from the equilibrium position?Show your work. [2 marks] (c) The pendulum is pulled aside until it is 0.386 m above its lowest position and released. The pendulum is designed to emit sound waves at a frequency of 440 Hz; however, as it swings toward and away from an observer, the frequency appears to vary slightly . What is the apparent frequency of the sound from the pendulum as it swings at its maximum speed toward an observer?Assume the speed of sound is 345m/s Show your work. [4 marks] (d) Regarding 2c, what is this phenomenon called? [1 mark]
