The picture is not loading as it requires a sign in.
However, I can tell you how to solve this.
Answer:
<span>As the wavelength gets shorter (closer together), the frequency of the wave increases.
Explanation:
The relation between frequency and wavelength can be described by the help of velocity as follows:
velocity = frequency * wavelength
This means that:
frequency = velocity / wavelength
Noting this equation, we will find that:
The frequency and the wavelength are inversely proportional to each other. This means that as the frequency increases, the wavelength decreases and vice versa.
Now, examining the choices given, we can find that the only statement showing the inverse relation between frequency and wavelength is:
</span><span>As the wavelength gets shorter (closer together), the frequency of the wave increases.
Hope this helps :)

Explanation:
Calcium chloride is an ionic compound as it is formed by transfer of an electron to each chlorine atom.
So, being an ionic compound calcium chloride is able to dissociate completely into water.
Hence, the dissociation reaction will be as follows.
Since, two electrons has been lost by single calcium atom. Therefore, calcium atom will have a charge of +2.
Thus, we can conclude that the charge on the calcium ion, in elementary units is +2.
I might not be right but I think the empirical formula is NO2
Answer:
3.6 times 10^4
Explanation:
Scientific notation is between 1-9. So, we move 36000 to 4 decimal places. SO it would be 3.6 times 10^4. Scientific Notation always has the base of 10 . Enjoy :)
