Answer:
3200 m/s
Explanation:
The speed of Sound through Argon is 319.
The speed of sound in any chemical element in the fluid phase has one temperature-dependent value. In the solid phase, different types of sound wave may be propagated, each with its own speed: among these types of wave are longitudinal (as in fluids), transversal, and (along a surface or plate) extensional.
If argon could exist as solid, then 3200 m/s is the best speed.

Answer:
The critical angle for the liquid when surrounded by air is 30 degrees.
Explanation:
Given that,
The angle of incidence is 33.5° and the angle of refraction is 19.3°. Firstly, we can find the refractive index of the liquid. It can be calculated using Snell's law as :
![n=\dfrac{\sin i}{\sin r}\\\\n=\dfrac{\sin (33.5)}{\sin (19.3)}\\\\n=2](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B%5Csin%20i%7D%7B%5Csin%20r%7D%5C%5C%5C%5Cn%3D%5Cdfrac%7B%5Csin%20%2833.5%29%7D%7B%5Csin%20%2819.3%29%7D%5C%5C%5C%5Cn%3D2)
The critical angle is given by :
![\theta_c=\sin^{-1}(\dfrac{n_1}{n_2})](https://tex.z-dn.net/?f=%5Ctheta_c%3D%5Csin%5E%7B-1%7D%28%5Cdfrac%7Bn_1%7D%7Bn_2%7D%29)
Here,
is refractive index of air and
is refractive index of liquid.
![\theta_c=\sin^{-1}(\dfrac{1}{2})\\\\\theta_c=30^{\circ}](https://tex.z-dn.net/?f=%5Ctheta_c%3D%5Csin%5E%7B-1%7D%28%5Cdfrac%7B1%7D%7B2%7D%29%5C%5C%5C%5C%5Ctheta_c%3D30%5E%7B%5Ccirc%7D)
So, the critical angle for the liquid when surrounded by air is 30 degrees.
Answer:
no current
Explanation:
Current is induced in the wire if the circuit is complete and the magnetic flux linked with it also changes. Due to change in flux, an emf gets induced. Its magnitude is given by :
![\epsilon=\dfrac{-d\phi}{dt}](https://tex.z-dn.net/?f=%5Cepsilon%3D%5Cdfrac%7B-d%5Cphi%7D%7Bdt%7D)
But in this case, a short piece of wire is not attached to anything and move it up and down in a magnetic field. It means that the circuit is not complete. It act as a open circuit. Hence, no current is induced in the wire.
