A 2.00-m-long rope has a mass of 0.100 kg. The tension is 55.0 N. An oscillator at one end sends a harmonic wave with an amplitude of 1.00 cm down the rope. The other end of the rope is terminated so all of the energy of the wave is absorbed and none is reflected. What is the frequency of the oscillator if the power transmitted is 120 W?
A nonconducting thin layer carries charge with a uniform density of 8.40 µC/cm2. (a) What is the electric field 3.80 cm in front of the wall if 3.80 cm is small compared with the dimensions of the wall? magnitude and direction?
A photoelectric-effect experiment determines a stopping potential of 1.93 eV while light of 200 nm is used to illuminate the cathode.
A ship's anchor weighs 5000 N. Its cable passes over a roller of negligible mass and is wound around a hollow cylindrical drum of mass 380kg and radius 1.10m. The drum is mounted on a frictionless axle. The anchor is released and drops 16 m to water.
Explain why heat can only be transferred from a hot object to a cold object and not the other way around.
