A particle that is moving in a straight line slows uniformly from 50.0 m/s to 20.0 m/s in 6 second.
Determine what is the constant acceleration?
Determine how far did the particle travel during these 6 seconds?
in electronic equipment wires that carry equal but opposite currents are often twisted together to reduce their
A simple pendulum consists of a ball connected to one end of a thin brass wire. Determine the change in the period of the heated pendulum
A laser produces a 6.50-mW beam of light, consisting of photons with a wavelength of 621.9 nm. (a) How many photons are emitted by the laser each second? Incorrect: Your answer is incorrect. Your response differs significantly from the correct ans..

If 100,000 MHz radar waves are incident on a plane coated with a polymer whose index of refraction is n = 1.50, how thick would you make the coating
A wave on the surface of the ocean with wavelength 44m is travelingeast at a speed of 18m/s relative to the ocean floor. If on, this stretch of ocean surface, a powerboat is moving 15m/s (relative tothe ocean floor), how often does the boat encoun..
A ray in a glass is incident onto a water-glass interface, at an angle of incidence equal to half the critical angle for that interface. The indices of refraction for water and the glass are 1.33 and 1.94, respectively. The angle that the refracted r..
A string of a violin is 32 cm long between fixed points with a fundamental frequency of 440 Hz and a mass per unit length of 7.2 x 10-4 kg/m. What are the wave speed and the tension in the string
a small excursion boat with a flat deck bobs up and down excuting simple harmonic motion due to the waves on a lake.
A circus performer stretches a tightrope between two towers. He strikes one end of the rope and sends a wave along it toward the other tower. He notes that it takes the wave 0.695 s to reach the opposite tower, 20.0 m away. If a 1.00-m length of the ..
There are Z protons in the nucleus of an atom, where Z is the atomic number of the element. An α particle carries a charge of +2e. In a scattering experiment, an α particle, heading directly toward a nucleus in a metal foil, will come to a halt when ..
A gymnast of mass 56.0 {rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {rm m/s^2} for the acceleration of gravity.
