Question 1. Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wavefronts in front of the source compare to those behind it? (Note: To draw a picture, you can use MS Paint or any other drawing software you may have. You can save the image file as a jpg or a bmp and then insert it into the Word document.)
Question 2. Imagine a small observer is positioned in front of the cork in your picture above. As the cork approaches, the observer measures the wavelength of the waves passing by. How does this wavelength compare to that measured from behind the source?
Question 3.. Imagine that this same observer measures the frequency of the waves instead of wavelength. How does the frequency measured in front of the source appear to the observer compared to the frequency measured from behind?
Question 4. How do these results help explain why a car’s engine sounds different as the car approaches you compared with after it passes?
A speedboat starts from rest and accelerates at +2.01 m/s2 for 6.95 s. At the end of this time, the boat continues for the additional 5.70 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at -1.49 m/s2 for 8.20 s.
Three blocks, each of mass 12 kg are on the frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 1.1 m/s2. What is the net horizontal force on b..
Find the value of Q that would make the thickness of the equivalent body 0.1 times its length (i.e the value of y at the dividing streamline at x=0 is 1/10 of the x coordinate at the aft stagnation point.).
