Q. Find the critical angle theta_ce for e-waves in calcite. The index of refraction for light with electric field parallel to the optical axis (called extraordinary waves or e-waves) is 1.4864. The index of refraction for light with electric field perpendicular to the optical axis (called ordinary waves or o-waves) is 1.6584.
Q. A copper block rests 30.0 cm from the center of a steel turntable. The coefficient of static friction between the block and the surface is 0.53. The turtable starts from rest and rotates with a constant anfular acceleration of 0.50 rad/s2. After what time interval will the block start to slip on the turntable?
A rifle fires a 2.39 10-2-kg pellet straight upward, since the pellet rests on a compressed spring that is released when the trigger is pulled. The spring has a negligible mass and is compressed by 9.17 10-2 m from its unstrained length. The pellet r..
The heat of vaporization of ethyl alcohol is about 200 cal/g. If 2.3 kg of it were allowed to vaporize in a refrigerator, how many grams of ice will be formed from 0°C water.
A uniform density cube of mass m, side 2b, and center at C is placed on a fixed horizontal cylinder of radius r and center O in Earth's gravitational field. The cube is originally put so that C is centered above O, but it can roll from side to side w..
The electrons in a metal that produce electric currents behave approximately as molecules of an ideal gas. The mass of an electron is me = 9.109x10-31 kg. If the temperature of metal is 311 K, what is the root-mean-square speed of the electrons.
In this week's video, Bill Goodykoontz talks about morality and ethics in pop culture. The freedom of speech and expression allows the variety of pop culture media to be released, which may sometimes be offensive material. Can pop culture still have ..
The resistance of the loop is 0.490 ohms. A magnetic field parallel to z-axis is given by B= 0.830 y^2 t, where B is in tesla, y in meters, and t in seconds. What is the size of the induced current in the loop at t = 0.470s .
A space traveler weighs 565 N on earth. What will the traveler weigh on another planet whose radius is 3 times that of earth and whose mass is twice that of earth.
A 150g ball and a 250g ball are connected by a 34cm long, massless, rigid rod. The balls rotate about their center of mass at 130 . what is the speed of ball of 150 g.
250 kg ball is dropped to the floor from a height of 1.0 m and upon rebounding, reaches a height of .60 m. What is the impulse delivered to the ball by the floor?
A 500 turn solenoid with a length of 20 cm and a radius of 3.0 cm carries a current of 3.0 A. A second coil of four turns is wrapped tightly about this solenoid so that it can be considered to have the same radius as the solenoid. Find when the curre..
