A ray of sunlight is passing from diamond into glass. The angle of incidence is 37.60o. The indices of refraction for the blue and red components of the ray are: blue: (ndiamond = 2.444, nglass = 1.531) and red: (ndiamond =2.410, nglass =1.520). Find the size of angle between the refracted blue and red ray in the glass.
Ropes utilized in rock climbing are "springy" so they cushion a climber's fall. A particular rope has a force law given by F=-kx +bx^2, where k=223 N/m, b=4.1 N/m^2 and x is the amount of stretch? Discover the potential energy stored in this rope whe..
Coyote is on a rocket that has acceleration of 10m/s^2, initially at rest at the top of a flat, level cliff. A roadrunner traveling at a constant speed of 25mil/hr passes the coyote, How far ahead of the coyote is the roadrunner when the fuse ignit..
A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open at the top. Friction is absent. The spring constant of the spring is 4360 N/m. The piston has a negligible mass and a radius of 0.0300m.
