One of the early challenges of tracking astronaut's health in space was that it was difficult to measure their mass. Two different approaches were used by different space agencies. The Russians developed the Body Mass Measuring Device, which uses springs to determine masst Meanwhile, NASA developed the Space Linear Acceleration Mass Measurement Device based on Newton's second law. Part 1) Select all the true statements. [3 For a mass on the end of a spring, a greater amplitude for oscillations indicates a heavier mass on the end of spring. For a mass on the end of a spring, a longer period for oscillations indicates a heavier mass on the end of spring. C] For a pendulum with a fixed length, a longer period for oscillations indicates a heavier mass on the end of the pendulum. '/ A mass on the end of a spring undergoes simple harmonic motion when it is displaced from its equilibrium position. Correct answer, well done. You have correctly answered this part. Marks for this submission: 0.33/033. Part 2) An astronaut with a mass of m = 65.2 kg uses the Body Mass Measuring Device on the International Space Station. The mass of the measuring tool (seat, etc.) is m, = 13.9 kg. If the period of oscillation is T = 1.96 5, what is the spring constant of the measuring device? Part 3) Another astronaut gets onto the device. For this astronaut, the period of oscillations are T2 = 2.27 5. What is the mass of this astronaut? m= kg Frequency generator Mass Part 1) A frequency generator that generates a signal at a fixed frequency is used to send a transverse wave along a piece of string that is placed over a pulley and supports a hanging mass as shown in the figure above The hanging mass generates tension in the string equal to its weight force. If the hanging mass is increased, select the option from the dropdown lists that make the statements below true. a) The speed of the wave will (No answer given) b) The frequency of the wave will (No answer given) c) The wavelength of the wave will (No answer given) Pa rt 2) Transverse waves travel with a speed of 10.6 m/s along a construction crane's cable that is supporting a load. The load supplies a tension of 64.0 kN to the cable. If the wave frequency is 0668 HZ, what is the wavelength? Part3) What tension is required to make the wave in Part 2 travel with a speed of 28.4 m/S in the same cable? Tension 2 kN Part 1) A wave travelling on a piece of string is described by the equation: y(x, t) = A sin(kx (of) Which direction is this wave travelling? (No answer given) : One end of the string is clamped in place. When the wave is reected off this end, will it undergo a phase change? (No answer given) Part 2) Consider the wave described by: y(x, t) 23.52 sin(101 x32.3 t) mm Write down an equation to describe an identical wave travelling in the opposite direction. Remember to include "*" for multiplication. y(x, t) = sin( ) mm Part 3) If both these waves are present in the same piece of string, a standing wave results. Write an expression for this standing wave. y(x, t) = sin( ) cos( ) mm run I, Which of the following statements are true about a harmonic sound wave? C] As a sound wave passes from one medium to another (9.9., from air to water), the wavelength of the sound wave changes. C] The frequency of the fourth harmonic is four times the fundamental frequency. C] The speed the wave travels at is dependent upon the medium. C] As a sound wave passes from one medium to another (e.g., from air to water), the frequency of the sound wave changes. An extendable pipe is open at both ends. A speaker can be found a short distance from one end. Assume that end effects are negligible. Speaker 5 Figure 1. A speaker is played through an extendable pipe that is open at both ends. Part 2) A steady note with a fixed frequency of f = 1480 Hz is played through the speaker. The length of the pipe is slowly increased from a very short length until the first maximum in sound intensity is heard. This occurs when L = 12 cm. What is the speed of sound in the pipe? \"Sm Part 3) The length continues to increase. At what length will the next maximum in the intensity of sound be detected
