Answer:
The distance between two posts
Explanation:
As the students have already measured the amount of time necessary for the wave to oscillate up and down that is on the string between two posts,They have to measure the speed of the wave.
ie v=fλ
<em>They have to measure distance between the posts.
</em>
Because wavelength is equal to the distance between the posts ie full length of string.
The frequency of the wave is calculated by
f=
1/T
Where is the time period which the students have calculated ie the amount of time taken to oscillate up and down,
Thus the wave speed is calculated using formula
v=λ/T
Answer: 656 rad/s
Explanation:
Angular frequency is also called radial circular frequency. It measures angular displacement per unit time. It's unit is rad/s. It is also greater than the regular frequency by a factor of 2π. Hence, angular frequency, ω = 2πf
If 1 revolution(20 hole) = 20 cycle per revolution.
Then, 2087.8(cycle) = x revolution
X revolution = 2087.8/20)
X revolution = 104.39 revolution
ω = 2πf
ω = 2 * π * 104.39
ω = 655.98676
ω ~ 656 rad/s
Storing music digitally requires less storage room than analog records or tapes. Digital music is easier to copy and the copies are the same as the original. The quality of the signal does not degrade over long periods of time.
