As an admirer of thomas young, you perform a double-slit experiment in his honor. you set your slits 1.19 mm apart and position your screen 3.53 m from the slits. while young had to struggle to achieve a monochromatic light beam of sufficient intensity, you simply turn on a laser with a wavelength of 635 nm. how far on the screen are the first bright fringe and the second dark fringe from the central bright fringe? express your answers in millimeters.

The dot diagram represents the motion of the motorcycle as it moves from left to right

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?
