What is the frequency of a wave that has a wavelength of 0.78 m and a speed

Cerrena [4.2K]

Answer:

C. f = 440 Hz

Explanation:

In any wave, there is a fixed relationship between the wavelength (distance between two sucesive crests), the frequency (number of cycles per unit time) and the perturbation speed, as follows:

$v = \lambda * f (1)$

where v = speed of the wave

λ = wavelength

f = frequency

Replacing by the givens in (1) and solving for f, we have:

$f = \frac{343 m/s}{0.78m} = 440 Hz$

f = 440 Hz

Determine the change in internal energy of a monatomic ideal gas that expands from an initial volume of 1.53 m3 to a final volum

Illusion [34]

Answer:

Internal energy will be $2.05\times 10^5Joule$

Explanation:

We have given that initial volume $v_1=1.53m^3$

And final volume $v_2=2.87m^3$

Pressure $p=1.02\times 10^5Pa$

Now change in volume $dv=2.87-1.53=1.34m^3$

We know that change in internal energy is given by

$\Delta U=\frac{3}{2}nR\Delta T$ , here we know that

Work done $W=Pdv=nR\Delta T$

So $\Delta U=\frac{3}{2}PdV=\frac{3}{2}\times 1.02\times 10^5\times 1.34=2.05\times 10^5Joule$
