Answer:
168 Hz, 280 Hz and 392 Hz
Explanation:
The resonant frequencies for a closed pipe at one end is given by :
, n = 1,3,5...
The fundamental frequency, f₁ = v/4l = 56 Hz
For first overtone, put n = 3
For second overtone, put n = 5
For third overtone, put n = 7
So, the first three overtones are 168 Hz, 280 Hz and 392 Hz.
The work output of a machine is measured or calculated by measuring the output force and the output distance. Work output is the work done by a simple machine or any type of an engine model, it is the energy output, which for machines is always less than the energy input, due to factors such as friction of the moving parts.
Answer:
a strange world that has baffled scientists ever since it was discovered in 1930. It is not the large gas giant that one might expect to find in the outer reaches of the solar system.
