A laser beam travels from air (n=1.002) into glass (n=1.522)and then into gelatin. The incident ray makes a 58 angle with the normal as it enters the glass and a 36.4 angle with the normal in the gelatin.
a. Determine the angle of the refracted ray in the glass.
b. Determine the index of refraction of the gelatin.
Two objects of mass m and 9m undergo a completely inelastic collision in one dimension. what was the ratio of their speeds before the collision
to focus a camera on objects at different distances the converging lens is moved toward or away from the film so a
A 12kg block stays at rest on a horizontal surface without reasoning. A ball of 400g travels with a velocity of 16m/s with a direction 30o below the horizontal and crashes against the block and gets embedded in it.
a point charge q1 3.85nc is located on the x-axis at x 2.00m and a second point charge q2 -5.55nc is on the y-axis
A small block with mass m1 rest on a frictionless horizontal tabletop a distance r1 from a hole in the center of the table. A light, stretchless string tied to the small block passes down through the hole, and a larger block with mass m2 is suspen..
A spring (k=600N/m) is placed in a vertical position with its lower end supported by a horizontal surface. The upper end is depressed 20 cm, and a 4.0-kg block is placed on top of the depressed spring. The system is released from rest. How far above ..
The orbital period of Halley's Comet is calculated to be 75.5 years. Many other comets have orbits that extend much farther from the sun, and hence have much longer periods. At aphelion, a typical long-period comet is about from the sun; at perih..
A 1000 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 16 s, What is the rocket's speed as it passes through acloud 6200 m above the ground
Two blocks with masses M_1 and M_2 hang one under the other. For this problem, take the positive direction to be upward, find the tension in the lower rope
A 2-kg collar which can slide on a frictionless vertical rod is acted upon by a force P which varies in magnitude as shown. Knowing that the collar is initially at rest, determine
A wire of diameter 0.750 mm and length 30.0 m has a measured resistance of 2.40 ?. What is the resistivity of the wire
A positive charge of 1.000 C is located in a uniform field of 9.50×104 N/C. A negative charge of -0.500 C is brought near enough to the positive charge that the attractive force among the charges just equals the force on the positive charge due to th..
