Answer:
A. The sound wave will reflect off Buildings and automobiles.
Explanation:
This is because the sound waves would more likely propagate through diffraction through buildings and transmission through the air. It is also more likely to be absorbed by buildings than for multiple reflections to occur off buildings and automobiles. In the process of reflection, these materials would absorb the sound energy thereby reducing its ability to reflect.
I don't know your options but it's probably an insulator.

Answer:
Explanation:
The Newton's law in this case is:
Here, is the air temperture, C and k are constants.
We have

The energy of a photon is given by the following formula:
(1)
Where:
is the Planck constant
is the frequency
Now, the frequency has an inverse relation with the wavelength :
(2)
Where is the speed of light in vacuum
Substituting (2) in (1):
(3)
<u>Knowing this, let's begin with the answers:
</u>
<h2>(a) Microwave: 50.00 cm

For
<h2>(c) X-ray: 0.5 nm
</h2><h2 />
For
As we can see, as the wavelength decreases, the energy increases.
