The angle of incidence at a solid/liquid boundary is 60.4°, and the index of refraction of the solid is n = 1.96.
(a) Find what must be the index of refraction of the liquid such that the direction of the light entering the liquid is not changed?
(b) Determine the largest index of refraction that the liquid can have, such that none of the light is transmitted into the liquid and all of it is reflected back into the solid?
A boy is standing on a frozen lake (i.e. no friction) holding a rope that is attached to his sled. He pulls on the rope and exerts a horizontal force of 5.2 N, What is the acceleration of the boy
A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. She weighs 521 N. As the drawing shows, Find the tensions in the rope to the left and to the right of the mountain climber
What is order of the layers from top to bottom
One of the conditions for Uniform Circular Motion is that the acceleration be centripetal and directed toward the center of motion. Explain what would the effect be of non-zero acceleration parallel to the tangential velocity
A chair of weight 130 lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of = 45.0 fixed at an angle of 39.0below the horizontal and the chair slides along the floor.
The current in the circuit if the speed v is 0.75 m/s , determine which end of the rod is positive.
Original problem: a person walks at constant speedv1 along a straight line from A to B and then back alongthe line from B to A at constant speed v2, What is theaverage speed over the entire trip
A small statue is recovered in an archaeological dig. Its weight is measured to be 8.4 lb and its volume 0.04 ft3. Find what is the statue weight density
A wheel is rotating freely at angular speed 400 rev/min on a shaft whose rotational inertia is negligible. Find what fraction of the original rotational kinetic energy is lost
A skier starts from rest at the top of a 45-m hill, skis down a 30° incline into a valley, and continues up a 40-m-high hill. Both hill heights are gauged from the valley floor. Suppose that you can neglect friction and the effect of ski poles
