ind the frequency at which gain is maximized for the forced damped harmonic oscillator with equation

Answer:- b

Explanation:

The temperature of the diatomic atom's environment will vary the contributing kinetic energies for its heat capacity. At 60 K or below, the main contributor of energy is translational energy only. When the temperature rises up to about room temperature to 600 K, the contribution of rotational energy starts to be significant. When the temperature exceeds 3000 K, vibration energy is contributing to the heat capacity of a diatomic gas.

The formula for the specific heat capacity at constant volume is:

 where d is for degrees of freedom.

The translational motion contribute 3 degrees of freedom, meanwhile, the rotational and vibrational motion contributes 2 each for the degrees of freedom. Having 29.1 J/mol-K as the molar heat capacity at constant volume, the equation will be:

Having the degrees of freedom = 7 means that d.) translation, rotation, and the vibration is contributing.

Answer: B

Due to a single charge and the additional distance =2r, the electric field is E r times the distance of point y from the charge

New intensity is consequently equal to E/4.

From the point charge, the electric field extends in all directions. Spherical equipotential surfaces are represented by the circles. The vector sum of the individual fields may be used to compute the electric field from any number of point charges.

Volts per metre (V/m) is the electrical field's SI unit. The Newtons per coulomb are the same as this unit. These units have their roots in Newton, which stands for force, and Coulomb, which stands for charge.

The sound intensity of a jet engine radiating an acoustic power of 2.11×105 w sound at a distance of 50.3 m from the engine is approximately 6.64 [tex]W/m^2[/tex].

The intensity means the amount of loudness in it. The actual definition of intensity is the amount of power a sound has per unit area.

Mathematically, the intensity can be written as:

[tex]I=\frac{Power}{Area}[/tex]

The given data:

Power, P = [tex]2.11\times 10^5 W[/tex]

Area, A = [tex]4\pi d^2=4\pi (50.3)^2 m^2[/tex]

Bubba-Joe carries out a careful investigation to determine the melting point of salicylic acid, and concludes that the value is 161.4 degrees Celsius. The melting point of salicylic acid is known very well as 158.6  degrees Celsius. Bubba's percent error will be 1.74 %

Percentage error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage. In other words, the percent error is the relative error multiplied by 100.

estimated value of melting point = 161.4 °C

true value of melting point = 158.6 °C

percent error = ((true value - expected value) / expected value) * 100

The intensity if the frequency is reduced from f to f / 2 and the displacement amplitude doubled is I.

The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is stated. The period is the reciprocal of the frequency since it is the length of time for one cycle in a repeating occurrence. For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

Therefore, Final intensity of the speaker is,

[tex]I^{'} = \frac{1}{2}\rho (2\pi f^{'} )^{2}S_{max} ^{2}v\;\;\;\;-----equation(2)[/tex]

By dividing the equation (1) and (2), We get
