Textbook Question
Chapter 7, Problem 13SEQ
Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Explaining the Doppler Method. Explain how the Doppler method works in terms an elementary school child would understand. It may help to use an analogy to explain the difficulty of direct detection and the general phenomenon of the Doppler shift.

- 1. Record the slopes from the best fit lines for both the Thin Spring and the Thick spring. (What are the units of the slopes? They do have units! Be sure to show the units in your answer here). 2. Which spring has the graph with the greater slope, the Thin Spring or the Thick Spring? Answer in a complete sentence. 3. The slope shows the amount of displacement of the spring per amount of hanging mass. Use either the slopes or the equations from your trendlines to predict how much the spring would stretch for a 500 g (0.50 kg) mass. Do this for both the Thin and Thick Springs. 4.The Spring Constant you adjusted in lab is related to the stiffness of the spring – stiffer springs need more mass to “pull” them down the same displacement. If you increase the spring constant, what would happen to the slope (rise/run) of the graph you create?

- I need urgent answers on the photo provided here pls. Thank you so much.arrow_forwardPlease explain in full detail as I am trying to understand this concept! thank you! a. Sketch a diagram including Earth, Sun, and Mars, with attention to scale of distance (Mars is about 1.5 AU from the Sun) showing a faster trajectory from Earth to Mars than the minimal energy trajectory discussed in the lecture. b. Without doing a calculation, how would the arrival velocity of the spacecraft at Mars for the case in (a) compare to the spacecraft arrival in the class example? The lecture example had the spacecraft arriving at Mars with a velocity of 22.49 km/sec. c. The average velocity of Mars in orbit around the Sun is 24.08 km/sec. Comment on the trade-offs between trajectories, arrival velocities and velocity changes (delta V) required to enter an orbit around Mars.arrow_forwardIdentify which of the cyclists ended their trip closest to home.
