The frequency of the third harmonic if the pipe is closed at one end is = 102.93  Hz.

To find the frequency of the third harmonic if the pipe is closed at one end, we use the formula,

[tex]f_{n} =nf_{1}[/tex]=[tex]n\frac{v}{4L}[/tex]  , in this case n= 1,3,5,7,9.....

Here we are given,

L= The length of the pipe = 4.137 m.

v= speed of the sound at 16.164°C .

[tex]v_{0}[/tex]= speed of the sound at 0°C.=331 m/s

Before finding the frequency we have to find the speed of the sound at 16.164°C. To find v, we are using the formula,

[tex]v=v_{0 } \sqrt{\frac{T_{2} }{T_{1} } }[/tex]=[tex]331\times \sqrt{\frac{(273+16.164) }{273 }[/tex]=340.65 m/s.

We have to find the frequency of the third harmonic, so according to the question, n=5

Now we put the known values in the first equation, we can find that

[tex]f_{n}=n\frac{v}{4L}[/tex]

Or,[tex]f_{n} = 5\times\frac{340.65}{4\times 4.137}[/tex]=102.93 Hz.

Therefore, from the above calculation we can conclude that if the pipe is closed at one end the frequency of the third harmonic is 102.93 Hz.

Potential energy is position relative, and kinetic energy is motion relative. The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again.

Potential energy defined as :

The energy stored in a body due to either its position or change in shape is known as potential energy. Water stored in a reservoir is an example of potential energy.

PE=mgh

where,

PE is the potential energy

m is the mass of the body

g is the acceleration due to gravity

h is the height above the surface of the earth

Kinetic energy is defined as :

Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.

Kinetic Energy Formula:

For the Kinetic formula, Ek, is certainly the energy of a mass, m, motion, of course, is v2.

KE = [tex]\frac{1}{2} mv^{2}[/tex]

KE = Kinetic energy

m = mass of the body

v = velocity of the body

What are the similarities between potential energy and kinetic energy?

One of the most important similarities between potential energy and kinetic energy is that they can both be converted into each other's form of energy. When a force is applied to potential energy it converts to kinetic energy. This means that when an object such as a ball is still it has the potential to move.

The critical value of t for a two-tailed test with 14 degrees of freedom using = 0. 5 is ±164.5577.

In hypothesis testing, critical values are one of the two approaches which allow you to decide whether to retain or reject the null hypothesis.

The critical value approach consists of checking if the value of the test statistic generated by your sample belongs to the so-called rejection region, or critical region, which is the region where the test statistic is highly improbable to lie. A critical value is a cut-off value (or two cut-off values in case of a two-tailed test) that constitutes the boundary of the rejection region(s). In other words, critical values divide the scale of your test statistic into the rejection region and non-rejection region.

To determine critical values, you need to know the distribution of your test statistic under the assumption that the null hypothesis holds. Critical values are then the points on the distribution which have the same probability as your test statistic, equal to the significance level α. These values are assumed to be at least as extreme at those critical values.

Explanation:

If a force always acts perpendicular to an object's direction of motion, that force cannot change the object's kinetic energy. It is a true statement .

Kinetic energy is the energy that an object possesses due to its motion. It is basically the energy of mass in motion. Kinetic energy can never be negative and it is a scalar quantity i.e. it provides only the magnitude and not the direction.

According to law of conservation of mechanical energy change in potential energy is equal and opposite to the change in the kinetic energy.

According to the principle of conservation of mechanical energy, The total mechanical energy of a system is conserved i.e., the energy can neither be created nor be destroyed; it can only be internally converted from one form to another if the forces doing work on the system are conservative in nature.

since, potential energy is stored in the form of work done

Work done = Fs cos (theta)

If force always acts perpendicular to an object's direction of motion
