To develop this problem it is necessary to apply the oscillation frequency-related concepts specifically in string or pipe close at both ends or open at both ends.
By definition the oscillation frequency is defined as
Where
v = speed of sound
L = Length of the pipe
n = any integer which represent the number of repetition of the spectrum (n)1,2,3...)(Number of harmonic)
Re-arrange to find L,
The radius between the two frequencies would be 4 to 5,
Therefore the frequencies are in the ratio of natural numbers. That is
Here f represents the fundamental frequency.
Now using the expression to calculate the Length we have
Therefore the length of the pipe is 1.3m
For the second harmonic n=2, then
Therefore the length of the pipe in the second harmonic is 2.6m
Answer:
Chemical you bodily functions while you are jumping
Sound you feet hitting the ground and the jump rope smacking the ground
Mechanical is you jumping up and down and the jump rope spinning a constant direction
Explanation:
Answer:
A. T=126N
B. T=63N
Explanation:
To determine the tension in each given blocks, we first determine the acceleration of each block. It obvious that each mass will move with the same acceleration since the string connecting them is massless.
Hence using the equation of force we have
F=ma
Where m=total mass of blocks,
a=acceleration
F= force applied in this case the tension in the string.
For a 134 identical masses with an applied force of 134N, the acceleration of each mass can be computed as
134=134m*a
a=134/134m
a=(1/m )m/s²
a. To calculate the tension in the string between the 126 and 127 block, we use the equation below
T=ma
Since the number of blocks before the string is 126, we multiply the mass of each block by 126.
Hence the tension can be computed as
T=126m*a
Since a=1/m then
T=126m*1/m
T=126N
B.To calculate the tension in the string between the 63 and 64 block, we use the equation below
T=ma
Since the number of blocks before the string is 63, we multiply the mass of each block by 63.
Hence the tension can be computed as
T=63m*a
Since a=1/m then
T=63m*1/m
T=63N
