Answer:
Length of pipe 
meter
Explanation:
Speed of a transverse wave on a string
where F is the tension in string and 
is the mass per unit length
Thus,
Substituting the given values we get -
Speed of a transverse wave on a string
For third harmonic wave , frequency is equal to
Substituting the given values, we get -
Length of pipe
Substituting the given values we get
for first harmonic wave
Length of pipe meter
" 478 watts " means 478 joules per second.
In 14 seconds, the total work or energy is (14 x 478) = <em>6,692 joules</em>
The Electric current is 1.11* 10^{-4}A
Given that the coil's radius is 3.55 cm (0.35 m),
The formula for the coil's area is A = r2 A = (3.14) (0.35)2 = 0.005024 m2.
R = Resistance = 600 N = Number of spins = 500 B = Magnetic field = (0.0120)
t + (3 x 10⁻⁵) t⁴
The number t = 5 is substituted for taking the derivative at both the induced current and the electric current.
The Electric current is therefore 1.11* 10^{-4}A
Electric current - The rate of electron passage in a conductor is known as electric current. The ampere is the electric current's SI unit. Electrons are little particles that are part of a substance's molecular structure. These electrons can be held loosely or securely depending on the situation.

Answer: B
To measure a lower-pitched sound wave, you would
measure fewer compressions per second. Pitch <span>relates to frequency by measuring how many times a second the
particles vibrate. Therefore, the lower-pitched sounds, the fewer compression waves or sound waves are produce because low-frequency
sounds have greater distance between each wave.</span>
Moreover,
the frequency of a wave is measured as the number of complete
back-and-forth vibrations of a particle of the medium per unit of time. <span>The universal unit for frequency used is
the Hertz (abbreviated Hz), where 1
Hertz = 1 vibration/second. </span>
