A hollow log, open at one end, is struck with a stout stick. The hollow cavity of the log is 6 meters long, and the pressure waves that constitute sound travel at 342m/s. What are the frequencies of the resulting first four harmonics?© BrainMass Inc. brainmass.com October 24, 2018, 6:39 pm ad1c9bdddf
Since the log is open at one end and close at the other, the first four modes in this log ...
The solution contains the equations and calculations necessary to solve the problem.
Wave Dynamics and Water Vapor Pressure
See the attached file.
Equations describing wave dynamics and dispersion are used to deduce the following
A wave of period 10s approaching the shore has a height of 1m in deep
water. Calculate (use ?=1.03×103 kg m-3)
(a) The wave speed and group speed in deep water =
(b) The wave steepness in deep water =
(c) The wave power per metre length of crest in deep water =
(d) The wave power per metre length of crest in water 2.5 m deep =
The super cooling of water into droplets is described for the scenario below
Ice particles and super cooled water droplets exist in the same cloud at a temperature if T = 260 K. The water vapor pressure in the cloud is P h2o = 2.50mb. I have to develop an argument that shows the liquid droplets will tend to evaporate and the ice particles will tend to grow.
