Option B is the right choice.

Explanation:

Given:

Two sounds waves lets say S_1 and S_2 having same pitch but

We have to find the property which from the options and identify which one is greater for S_2 .

Lets take one and one analysis of the terms.

Frequency :

It is how fast the sound wave is oscillating. Frequency is $f=\frac{1}{T}$ hertz. The faster the sound wave oscillates the higher pitch it will have.

According to the question the pitch is same so the frequency will be same for both the waves.

Amplitude :

The loudness of the sound increases with an increase in the amplitude of sound waves.It is the maximum amount of displacement of a particle on the medium from its rest position.

Wavelength :

Distance between two consecutive crest (high) or trough (low) is called wavelength.Shorter wavelength will have higher frequency.

Here the frequency is same so the wavelength for S_1,S_2 will be same.

Speed in air:

Speed of sound in a same medium is usually same.Speed of sound in air is 343 m/s.

So,

Amplitude of S_2 S_1 .

Here the amplitude of the louder sound wave will be greater .

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by mathematical calculations before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of uranus led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
