When the current in a toroidal solenoid is changing at a rate of 0.0200 A/s, the magnitude of the induced emf is 12.7 mV. When t

he current equals 1.50 A, the average flux through each turn of the solenoid is 0.00458 Wb. How many turns does the solenoid have?

Answer:

N  =  208 \  turns

Explanation:

From the question we are told that

    The  rate of  current change is  \frac{di }{dt}  =  0.0200 \ A/s

    The  magnitude of the induced emf is  \epsilon =  12.7 \ mV =  12.7 *10^{-3} \ V

     The  current is  I  =  1.50 \  A

      The  average  flux is  \phi =  0.00458 \ Wb

Generally the number of  turns the number of turn the solenoid has is mathematically represented as  

            N  =  \frac{\epsilon_o  *  I}{ \phi *  \frac{di}{dt} }

substituting values

           N  =  \frac{ 12.7*10^{-3}  *   1.50 }{ 0.00458 *   0.0200 }

            N  =  208 \  turns

kompoz [17]

Answer:

g(h)=9.81943\ m/s^2

Explanation:

The given function is

g(h)=\dfrac{3.99\times 10^{14}}{(6.374\times 10^6+h)^2}

Now h = the height from the surface of the Earth

Here the building is 458 m tall

g(458)=\dfrac{3.99\times 10^{14}}{(6.374\times 10^6+458)^2}

\Rightarrow g(458)=9.81943\ m/s^2

So,

g(h)=9.81943\ m/s^2

In a physics lab, you measure the vibrational-rotational spectrum of hcl. the estimated separation between absorption peaks is:_
BlackZzzverrR [31]

The appropriate value in blank given is Δf = 5.5 x 10^{11} Hertz.

We have vibrational - rotational spectrum Hydrochloric Acid.

We have to investigate the estimated separation between absorption peaks and fill the blank.

<h3>What is vibrational - rotational spectrum ?</h3>

Rotational–vibrational spectroscopy is a branch of molecular spectroscopy. It deals with the infrared and Raman spectra of molecules in the gaseous phase.

According to the question -

The estimated separation between absorption peaks in the vibrational-rotational spectrum of HCl is denoted by Δf and is equal to -

Δf = 5.5 x 10^{11} Hertz

Hence, the appropriate value in blank given is Δf = 5.5 x 10^{11} Hertz.

Define bond length using your own words​
Brut [27]

Answer:

the free encyclopedia. In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.
