A piece of curved glass has a radius of curvature of 10.0 m and is utilized to form Newton's rings, as in Figure 27.16. Not counting the dark spot at the center of the pattern, there are one hundred dark fringes, the last one being at the outer edge of the curved piece of glass. The light being utilized has a wavelength of 654 nm in vacuum. What is the radius of the outermost dark ring in the pattern?
A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. She weighs 586 N. As the drawingshows, she is closer to the left cliff than to the right cliff,with the result that the tensions in the left and right sid..
