Light is incident at an angle of 43 degrees on the surface ofa dimond. Find the angle of refraction?
A simple pendulum is made from a string that is 0.65m inlength with a mass of 0.2 kg attached to the free end. The mass is pulled to one side through a small angle and released fromrest. What s the angular frequency and period of the pendulum? if t..
a magnetic field is directed at a 40 degree angle to a plane circular loop of wire with a radius of 26.8 cm draw a diagram showing the wire loop angle and magnetic field. determine the induced emf in the wire loop
A motorcycle, which has an initial linear speed of 6.4 m/s, decelerates to a speed of 1.5 m/s in 5.7 s. estimate the angular displacement (in rad) of each wheel
A shuttle with a mass of 18,000 kg is traveling at 6,750 m/s when retrorockets are fired to increase the shuttle's speed. What is the final speed of the shuttle after the engines shut down
A tuning fork vibrating at an unknown frequency is held over the open end of a tube partially filled with water. If the fundamental resonant mode is heard when the water level is 30cm below the open end, what is the frequency of the tuning fork?
the young modulus of a metal wire is 0.17 tpa and its cross-sectional area is .18mm2. the wire is extended by a force
The photoelectric effect experiment is often carried out by using a mercury light source to illuminate a particular surface. What is the work function of this surface
Some amusement park rides move you back and forth in the horizontal direction. Why is this motion so much more disturbing to your body than cruising at a high speed in a jet airplane.
A block of mass 16.7 kg supported by a vertical massless cable is initially at rest. The block is then pulled upward with a constant acceleration of 4.89 m/s2. a) What is the tension in the cable? b) What is the magnitude of the net force acting o..
Explain how does a magnitude of the electrical force between a pair of charged particles change when they are brought to half their original distance of seperation?
How does the magnitude of electrical force between a pair of charged objects change while the objects are moved twice as far apart? Three times as far apart.
