Acommuter train passes a passenger platform at a constant speed of 40.4 m/s. the train horn is sounded at its characteristic frequency of 350 hz. (a) what overall change in frequency is detected by a person on the platform as the train moves from approaching to receding? (indicate whether the frequency increases of decreases with the sign of your answer.) the response you submitted has the wrong sign. hz (b) what wavelength is detected by a person on the platform as the train approaches? your response differs significantly from the correct answer. rework your solution from the beginning and check each step carefully. m

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.

The pressure in car tires is often measured in pounds per square inch (lb/in.2), with the recommended pressure being in the range of 25 to 45 lb/in.2. suppose a tire has a pressure of 27.5 lb/in.2 . convert 27.5 lb/in.2 to its equivalent in atmospheres.
