Monochromatic light of a single light source of wavelength 560 nm is passed through two narrow slits B and C. The distance from the central maximum to the first dark band is 1.3 mm. If the perpendicular distance from the slits to the screen is 1.3 m, the distance between B and C is Blank 1. Fill in the blank, read surrounding text. mm. State your answer accurate to 2 decimal places.

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
