Unpolarized light passes through 5 parallel ideal polarizing filters. What is the ratio of the initial intensity to the final intensity of the light
A bobsled slides down an ice track starting (at zero initial speed)from the top of a (n) 199 m high hill. The acceleration ofgravity is 9.8 m/s2. Neglect friction and air resistance and determine the bobsled's speed at the bottom of the hill.
A 1300 {rm N} crate slides 13 {rm m} down a ramp that makes the angle of 30^circ with the horizontal. If the crate slides at a constant speed, how much thermal energy is created.
A friend suggests that nuclei are composed of equal numbers of protons and electrons, and not neutrons. What evidence can you cite to show that your friend is mistaken?
Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Find the direction of the final velocity of the two-object system
A vertical jet of water having a nozzle exit velocity of 15 ft/s with a diameter of 1 in. suspends a hollow hemisphere as indicated in Fig. P5.56. If the hemisphere is stationary at an elevation of 12 in., determine its weight.
