The third harmonic frequency from the wave speed is 60.1 Hz.

<h3>What is wavelength?</h3>

Wavelength is the distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire.

Let's first find the wavelength of the wave.

The length wavelength relationship

\lambda = \frac{4}{3} L =  \frac{4}{3} . 4.28m = 5.706m

Now , we will find the third harmonic frequency from the wave speed formula:

v = f\lambda \\\\f = \frac{v}{\lambda} \\\\f = \frac{343\frac{m}{8} }{5.706m} \\\\f = 60.1 Hz

Therefore , the third harmonic (f3) is 60.1 Hz

A solenoid with 1000 turns has a cross-sectional area of 7.0 cm2 and length of 25 cm. How much energy is stored in the magnetic
Nimfa-mama [501]

Answer:

The energy stored in the solenoid is 0.18J

Explanation:

We need to obtain the inductance in order to calculate the energy:

L=\µ_o*N^2*\frac{A}{L}\\\\L=4*\pi*10^{-7}*1000^2*\frac{(7.0*10^{-4}m^2)}{25*10^{-2}m}\\L=3.51mH

The energy stored in the solenoid is given by:

U_g=\frac{1}{2}*L*i^2\\\\U_g=\frac{1}{2}*3.51*10^{-3}*10.0^2\\\\U_g=0.18J

Prove that..<br>please help<br>​
GaryK [48]

\large{ \boxed{ \bf{ \color{red}{Universal \: law \: of \: gravitation}}}}

Every object in the universe attracts every other object with a force which is proportional to the product of their masses and inversely proportional to the square of the distance between them. The forces along the line joining the centre of the two objects.

❍ Let us consider two masses m1 and m2 line at a separation distance d. Let the force of attraction between the two objects be F.

According to universal law of gravitation,

\large{ \longrightarrow{ \rm{F \propto m_1 m_2}}}

Also,

\large{ \longrightarrow{ \rm{ F \propto  \dfrac{1}{ {d}^{2} } }}}

Combining both, We will get

\large{ \longrightarrow{ \rm{F  \propto  \dfrac{ m_1 m_2}{ {d}^{2}}}}}

Or, We can write it as,

\large{ \longrightarrow{ \rm{F  \propto  \:  G \dfrac{ m_1 m_2}{ {d}^{2} }}}}

Where, G is the constant of proportionality and it is called 'Universal Gravitational constant'.

☯️ Hence, derived !!
