A gas as 30.0 Ml because pile of 1.4 add 1 that equals. To 1.5 and remove 10 so thebpresssure is 1399.93
To solve this exercise it is necessary to apply the equations related to the magnetic moment, that is, the amount of force that an image can exert on the electric currents and the torque that a magnetic field exerts on them.
The diple moment associated with an iron bar is given by,
![\mu = \alpha *N](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Calpha%20%2AN)
Where,

N = Number of atoms
y previously given in the problem and its value is 2.8*10^{-23}J/T
![L = 5.8cm = 5.8*10^{-2}m](https://tex.z-dn.net/?f=L%20%3D%205.8cm%20%3D%205.8%2A10%5E%7B-2%7Dm)
![A = 1.5cm^2 = 1.5*10^{-4}m^2](https://tex.z-dn.net/?f=A%20%3D%201.5cm%5E2%20%3D%201.5%2A10%5E%7B-4%7Dm%5E2)
The number of the atoms N, can be calculated as,
![N = \frac{\rho AL}{M_{mass}}*A_n](https://tex.z-dn.net/?f=N%20%3D%20%5Cfrac%7B%5Crho%20AL%7D%7BM_%7Bmass%7D%7D%2AA_n)
Where

![N = \frac{(7.9g/cm^3)(1.5cm)(5.8cm^2)}{55.9g/mol}(6.022*10^{23}atoms/mol)](https://tex.z-dn.net/?f=N%20%3D%20%5Cfrac%7B%287.9g%2Fcm%5E3%29%281.5cm%29%285.8cm%5E2%29%7D%7B55.9g%2Fmol%7D%286.022%2A10%5E%7B23%7Datoms%2Fmol%29)
![N = 7.4041*10^{23}atoms](https://tex.z-dn.net/?f=N%20%3D%207.4041%2A10%5E%7B23%7Datoms)
Then applying the equation about the dipole moment associated with an iron bar we have,
![\mu = \alpha *N](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Calpha%20%2AN)
![\mu = (2.8*10^{-23})*(7.4041*10^{23})](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%282.8%2A10%5E%7B-23%7D%29%2A%287.4041%2A10%5E%7B23%7D%29)
![\mu = 20.72Am^2](https://tex.z-dn.net/?f=%5Cmu%20%3D%2020.72Am%5E2)
PART B) With the dipole moment we can now calculate the Torque in the system, which is
![\tau = \mu B sin(90)](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%5Cmu%20B%20sin%2890%29)
![\tau = (20.72)(2.2)](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%2820.72%29%282.2%29)
![\tau = 45.584N.m](https://tex.z-dn.net/?f=%5Ctau%20%3D%2045.584N.m)
<em>Note: The angle generated is perpendicular, so it takes 90 ° for the calculation made.</em>
Responder:
<h2>
0.7Hertz
</h2>
Explicación:
Usando la fórmula para calcular la velocidad de onda que se expresa como se muestra.
Velocidad de una onda = frecuencia * longitud de onda
v = fλ
Dada la velocidad de onda = 14 m / sy longitud de onda = 20 metros
frecuencia f = v / λ
f = 14/20
f = 0.7Hertz
La frecuencia de la onda es de 0.7 Hertz.
Answer: Volume of a gas is inversely proportional to pressure of that gas in any container.
Explanation:
Hi, according to Boyle's Gas law, the volume of a gas is inversely proportional to the pressure of that gas, at a constant temperature.
The expression is:
P1.V1= P2.V2
V= 1/P
PV = k
Where:
P = pressure of a gas
V = volume of a gas
k = constant
