The fundamental frequency of this open-open pipe is 8.82 Hz
The quantity of waves that pass a set location in a predetermined period of time is known as frequency. Frequency is the number of full cycles per second in the alternating current direction for an oscillating or fluctuating current. The hertz, also known as Hz, is the accepted unit of frequency.
The temporal rate of change observed in oscillatory and periodic phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light, is specified by the frequency, an essential parameter in science and engineering.
Assume vs = 344 m/s
f1 = vs/2L
= 344 m/s/ 2∙64 ft/(3.281 ft/m)
= 8.82 Hz

Explanation:
Solidity means the quality or state of being firm or strong in structure. Density means the degree of compactness in a structure.
Answer:
a= 0.5m/s^2
Explanation:
Force applied on an object is known as
F=m.a (Newton's second law states it)
a=F/m
a=5/10=0.5m/s^2
<h2>Answer</h2>
1 V = 1 kg m2 s−² C
1 V = 1 kg m2 s−³ A−1
(one kilogram meter squared per second cubed per ampere)
<h2>Explanation</h2>
<em>The work required to move an electric charge of one coulomb through an electrical potential difference of one volt,</em>
<h2> Volts = Joules / Coulombs</h2><h2 />
Joules = Newton x metre
Volts = Nm / coulombs
Newton = kg x metre / second ²
Volts = kg x metre / second ² coulombs
Volt in terms of meters (m), seconds (s), kilograms (kg), and coulombs (c)
<h3>For further:</h3>
Coulomb = Amp * second
Volts = kg x metre / second ³ Amp

Answer:
(D) the sphere
Explanation:
The bodies given are Disk and Solid sphere (uniform sphere)
Moment of inertia of the bodies are
I(disk) =
I(sphere) = ![\frac{2MR^2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2MR%5E2%7D%7B5%7D)
Since the moment of inertia of sphere is less than that of disk, therefore sphere will reach the bottom first.
