Homework Answers
d = 8830 km = 8830,000 m ; t = 8.51 h = 31248 s
lambda = 6.6 km = 6600 m
we know that,
speed = dist/time
v = 8830000/30636 = 282.58 m/s
we know that,
v = f lambda
f = v/lambda = 282.58/6600m = 0.0428 Hz
Hence, f = 0.0428 Hz.

To understand electromagnetic radiation and be able to perform
calculations involving wavelength, frequency, and energy.
Several properties are used to define waves. Every wave has a
wavelength, which is the distance from peak to peak or
trough to trough. Wavelength, typically given the symbol λ
(lowercase Greek "lambda"), is usually measured in meters. Every
wave also has a frequency, which is the number of
wavelengths that pass a certain point during a given period of
time. Frequency, given the symbol...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
