We can use the formula,
1/R = 1/r1 + 1/r2 + 1/r3 + ....
Hope this helps!
Answer:
I think it is acute angle.
Explanation:
Because it is an angle between 0° and 90°. Hope this answer wil help you.
Answer:
frequency = 104.80 Hz
wavelength = 0.567 m
frequency = 104.80 Hz
wavelength = 3.27 m
Explanation:
given data
mass m = 9.4 g = 9.4 ×
m
length L = 85 cm = 0.85 m
tension T = 39 N
to find out
frequency and wavelength
solution
first we find frequency for second overtone
f = 3 /2L × √(T/μ) .............1
put here all value and
here μ = m/L = 9.4 ×
/ 0.85 = 1.10588 ×
kg/m
f = 3 /2(0.85) × √(39/1.10588 ×
)
f = 104.80 Hz
and
wavelength is 2L/3
wavelength = 2(0.85) / 3
wavelength = 0.567 m
and
frequency = 104.80 Hz
and
wavelength by speed of sound i.e 343 m/s
wavelength = speed / f
wavelength = 343 / 104.80
wavelength = 3.27 m
