Answer:
Length of the string = 0.24 m
Explanation:
The frequency (f) of vibration of stringed instruments is related to the Tension (T) in the spring by the relation
fₙ = (n/2L)√(T/μ)
where n = 1,2,3,4...
For third harmonic frequency, n = 3
L = length of the string = ?
T = tension in the string = 2.3 N
μ = linear density = 4.6 × 10⁻³ kg/m
f = frequency = 140 Hz
L = (n/2f)√(T/μ)
L = (3/(2×140))√(2.3/0.0046) = 0.40 m
Answer:
the frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.
f = v / l
where f is the frequency
v iss the linear speed
l is the wavelength
f = ( 345 m/s ) / ( 4.38 mm ) ( 1 m / 1000 mm )
f = 78767 per second

Answer:
true is the answer of the question
Oceania crust is typically made up of igneous rocks such as basalt. Igneous rocks are formed when lava flows from volcanoes cool and harden.
