Two students, student 1 and student 2, did the same experiment simultaneously to measure parallax. student 2's eyes are farther apart than student 1's eyes. the steps of the experiment are listed below. 1. hold the thumb out at arm's length. 2. look at the thumb and alternately open and close each eye. 3. estimate the distance by which the thumb appears to move with respect to background objects. based on the experiment, what would the students most likely conclude about the parallax method of measurement of star distances? a. both the parallax measurements should be taken at the same time b. parallax shift remains the same when measured by different instruments c. the shift in parallax while measuring star distances depends on the distance between the two points of observation d. parallax would be most effective in measuring distances to stars which are more than a billion light years away from earth

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”.
