Transverse waves on a string have a wave speed 8.00 m/s, amplitude 0.0700 m, and
wavelength 0.320 m. The waves travel in the -x-direction, and at t = 0, x = 0, the end of
the string has its maximum upward displacement. (a) Find the frequency, period, and
wave number of these waves. (b) Write a wave function describing the wave. (c) Find
the transverse displacement of a particle at x = 0.360 m at time t = 0.150 s
A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.5 s for the boat to travel from its highest point to its lowest, a total distance of 0.62 m. The fisherman sees that the wave crests are spaced 6.0 m apart. (a) How fast are the waves traveling? (b) What is the amplitude of each wave?
The range of audible frequencies is from about 20 Hz to 20,000 Hz. What is the range of the wavelengths of audible sound in air? (b) Visible light. The range of visible light extends from 400 nm to 700 nm. What is the range of visible frequencies of light? (c) Brain surgery. Surgeons can remove brain tumors by using a cavitron ultrasonic surgical aspirator, which produces sound waves of frequency 23 kHz. What is the wavelength of these waves in air
Find the velocity of a transverse wave in a string which is 4.0 m long with a total mass of 20g when uder a tension of 100N
On December 26, 2004, a great earthquake occurred off the coast of Sumatra and triggered immense waves (tsunami) that killed some 200,000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and in km/h? Does your answer help you understand why the waves caused such devastation?
1. What happened to the blade that was placed diagonally? Explain why that happened.
2. What happened to the blade that was placed horizontally using a fork?
3. In what way did the intermolecular forces affect the outcome of your activity?

A 26.3-kg child jumps off a diving board 1.5m above the surface of a pool. If all of the child’s potential energy is converted into kinetic energy, how fast is the child going when he hits the water?
A large chunk of ice with mass of 15.0kg falls from a roof 8.0m above the ground. Assume air resistance is negligible, kinetic energy is 14.25 J. Determine the speed of the ice when it reaches the ground.
(a) A sphere has a surface uniformly charged with 1.00 C. At what distance from its center is the potential 5.00 MV? (b) What does your answer imply about the practical aspect of isolating such a large charge? Show the process.
