Q. A rectangular slab (4.0 cm by 60 cm) of fused-quart glass is encased in a solid chunk of a transparent, synthetic material with the same index of refraction as diamond. A light ray strikes the middle of the 4-cm side of the slab, at an angle of 30 degrees as measured from that side of the slab to the ray. Find out the critical angle for the glass-synthetic interface (same as for the glass-diamond interface). Sketch a picture of the incoming ray as it interacts will all subsequent interfaces. Find out all angles of incidence and refraction, and label them on your diagram. If total internal reflection occurs at one of the interfaces, say so, and draw the reflected ray.
a loaded cart has a total mass of 227kg.if a 312n force acting at an angle of 30degree to the ground is applied. how much work is done in moving the cart 15meters?
A loudspeaker of mass 19.0 kg is suspended a distance of = 1.60 m below ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 3.30m . What is the tension in each of the cables.
Compute the average number of ion pairs produced along the entire paths of 12.0 MeV electrons that are brought to rest in air. Would number of ion pairs produced in soft tissue be significantly different.
Two sound sources radiating in phase at a frequency of 580Hz interfere such that maxima are heard at angles of 0 and 24 from a line perpendicular to that joining the two sources. Find out the seperation between the two sources. The velocity of sou..
Monochromatic light from a distant source is incident on a slit 0.750 {rm mm} wide. On a screen 2.00 {rm m} away, the distance from the central maximum of the diffraction pattern to the first least amount is measured to be 1.35 {rm mm}.
Follow that with some of her work on repressed memories. After completing your readings on the WebLink, the textbook, and the PowerPoint presentation, address the prompts for your assignment.
Two identical 0.13 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, where x2 = 0.04 m.
A proton is located at the origin, and a second proton is located on the x-axis at x=6.00 fm. (a) compute the electric potential energy associated with this configuration.
At what average rate does the force from the cable. A student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 15 {rm m}/{rm s} as the hand is 2.0 {rm m} above the ground.
Coherent light with wavelength 599nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00m from the slits. The first-order bright fringe is a distance of 4.84mm from the center of central brigh..
A 13 kg bucket of water of is suspended by a rope wrapped around a windlass that is a solid cylinder 0.400 m in diameter with mass 14.0 kg. The cylinder is pivoted on a frictionless axle through its center.
If you are in a car accident with an initial speed of 119 km/h and you are stopped by an airbag that inflates from the dashboard, over what distance should the airbag stop you for you to survive the crash.
