The number of oscillations made by guitar string in each minute will be 30720.
Given data:
The frequency of vibration is, f = 512 Hz.
The given problem is based on the concept of frequency of vibration. This can be defined as the number of oscillation completed in a seconds.
The number of oscillation in 1 second is,
Since, 1 minute = 60 seconds.
So, oscillations in 60 seconds is,
Thus, we can conclude that the number of oscillations in each minute will be 30720.

Answer:
30720 oscillation.
Explanation:
Frequency: This can be defined as the number of oscillation completed in a seconds. The S.I unit of frequency is Hertz.
From the question,
The frequency of the string set is 512 Hz,
These means that the spring set complete 512 oscillation in one seconds
I.e
if its completes in one seconds 512 oscillation.
Then, in one minutes, it will complete x oscillation.
x = 512×1min/1seconds
But 1 minutes = 60 seconds
x = 512×60/1
x = 30720 oscillation.
b. 440 V
c. 4,160 V
d. 69,000 V
Answers
Answer:
c. 4,160 V
Explanation:
Primary distribution voltage by electric utility company are often distributed around 3 Kv to 35 Kv, which would be a range between 3,000 V to 35,000 V because in order to be consumed by the public they use transformers to lower the voltage to less than 1Kv this can be used in domestic usage, so form the options the one that most likely would be used as a primary distribution voltage is 4,160 V.

Answer is : 80 Newtons
Answer: The output force is 80 N.
Explanation :
It is given that,
Mechanical advantage of a machine is 4
Input force is 20 N
We know that the ratio of output force to the input force gives the mechanical advantage of a machine.
Where
F' is the output force
F is the input force
F' = 80 N
So, magnitude of output force is 80 N.

Strong nuclear force is the colossal force possessing protons together in an atomic nucleus.
Alike:
They are both attractive forces.
They are both charge-independent
Different:
Vigorous nuclear force only applies to protons while gravity applies to all matter.
Gravity occurs on all levels of space while the robust nuclear force only occurs at the sub-atomic level.
