A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.6 s for the boat to travel from its highest point to its lowest, a total distance of 0.53 m. The fisherman sees that the wave crests are spaced 4.8 m apart. How fast are the waves traveling? (Give your answer in m/s.)

An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 185 m from where he is standing. You are 134 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you?

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 60 degrees at midnight and the high and low temperature during the day are 70 and 50 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t. D(t) =

A stationary boat in the ocean is experiencing waves from a storm. The waves move at 56 km/h and have a wavelength of 160 m, both typical values. The boat is at the crest of a wave. How much time elapses until the boat is first at the trough of a wave?

A f = 2п , Vx (L + 0.8D) f = frequency, in hertz v = 343 meters/second (speed of sound in air) A = area of opening, in m2 V = volume of round cavity, in m³3 L = length of neck, in m D = diameter of neck, in m

The motion of a body is described by the equation y = 2.10 sin (0.170πt), where t is in s and y is in m. a. Find the frequency (in hertz) b. Find the displacement at t = 2.00 seconds c. Find the displacement at t = 22.5 seconds

An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. The average speed of the transverse and longitudinal waves in rock are 8.8 km/s and 5.6 km/s respectively. A seismograph records the arrival of the transverse waves 82 s before that of the longitudinal waves. Assuming the waves travel in straight lines, how far away is the center of the earthquake?

A boat produces water waves as it sails along a river. You notice that 10 waves hit the bank in 4.8 seconds. If distance between successive wave crests is 3.8 centimeters, how far would these waves travel in 35 seconds. Express your answer in centimeters to at least 3 significant figures.

There is a tube of length 1.0 m with one end closed. You clapped your hand at the mouth of the tube once. The echo of the clap came back after 6.0 milliseconds. What is the velocity of sound in the tube ? 330 m/s O 320 m/s 290 m/s O 170 m/s
