If the angle θ in the two-source interference equations is small, then using small-angle approximations yields the equation ym=r(m+1/2)λd, where r is the distance from the sources to the points where they are being detected (in young's experiment the screen, in this example the road), and ym is the distance from the central maximum to the minimum of order m. use this equation to find the distance from the central maximum to the minimum in the previous part

The graph shows the prices of different numbers of bushels of corn at a store in the current year. the table shows the prices of different numbers of bushels of corn at the same store in the previous year. previous year number of bushels price of corn (dollars) 2 10 4 20 6 30 8 40 part a: describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. part b: how many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? show your work.
