Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4Β°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n β β n (9.8)(45β3 xi) i = 1 Ξ΄x express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
