1 In a Newton's-??rings experiment, a plano-??convex glass (n = 1.52) lens having diameter 10.0 cm is placed on a flat plate as shown in lecture notes. When 650-??nm light is incident normally, 55 bright rings are observed with the last one right on the edge of the lens.
(a) What is the radius of curvature of the convex surface of the lens?
(b) What is the focal length of the lens?
2. One leg of a Michelson interferometer contains an evacuated cylinder of length L, having glass plates on each end. A gas is slowly leaked into the cylinder until a pressure of 1 atm is reached. If N bright fringes pass on the screen when light of wavelength ? is used, what is the index of refraction of the gas?
3. Gold is the most ductile of all metals. For example, one gram of gold can be drawn into a wire 2.40 km long. What is the resistance of such a wire at 20°C? You can find the necessary reference information in your textbook.
An ion source is producing 6Li ions, which have mass 9.99 x10-27 kg and charge +e. The ions are accelerated by a potential difference of 30 kV and pass horizontally into the region in which there is a uniform vertical magnetic field of magnitude B..
A 0.50-kg object is attached to an ideal massless spring of spring constant 20 N/m along a horizontal, frictionless surface. The object oscillates in simple harmonic motion and has a speed of 1.7 m/s at the equilibrium position.
what is the minimum acceleration necessary for the plane to take flight.
An electric vehicle starts from rest and accelerates at a rate of 1.6 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle after that slows at a constant rate of 1.4 m/s2 until it stops. (1) How much time elapses from start to s..
What are sunspots and how are they related to the Sun's magnetic field? Is the magnetic field stronger weaker in sunspots? How does the temperature in a sunspot relate to the temperature in the rest of the photosphere.
Find out the precession period of the axis
How many kcal of heat must be withdrawn from 4.56 kg of steam at 125°C to change it to ice at -44.5°C.
An electric wire that has a mass of 5 kg for a 20m length is strung between two poles 20 m apart. What must be the tension in the wire if it is to take .80 seconds for a pulse to travel along the wire from one pole to the other.
Visualize the one cubic centimeter as formed by stacking up identical cubes, with one copper atom at the center of each. Conclude the volume of each cube.
A student sits on a rotating stool holding two 3kg objects. When his arms are extended horizontally, the objects are 1m from the axis of rotation.
Two 5000 kg passenger cars roll without friction (one at 1 m/s, the other at 2 m/s) toward one another on a level track. They collide, couple, and roll away together with the combined momentum.
If the maximum acceleration that is tolerable for passengers in a subway train is 2.45 m/s2 and subway stations are located 840 m apart, What is the travel time between stations
