Answer:
15"
Explanation:
Let x be the length of the longer part, then the length of the shorter part is 3x/5, or also x - 6
therefore we have the following equation:
3x/5 = x - 6
We can multiply both sides by 5
3x = 5x - 6*5
2x = 30
x = 30/2 = 15"
So the length of the longer part is 15"
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

The function of a circuit breaker is to stop a current
that is TOO GREAT, because that's often a sign that
some device in the circuit has failed.
Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
