It is a summer month position but it has no sunlight.
Maybe it is, maybe it isn't. We can't tell, until we see what "this" is.
Show us a drawing, an equation, an expression, a statement ... something !
Answer:

Explanation:
The frequency of a wave can be found using the following formula.

where <em>f</em> is the frequency, <em>v</em> is the velocity/wave speed, and λ is the wavelength.
The wavelength is 10 meters and the velocity is 200 meters per second.
- 1 m/s can also be written as 1 m*s^-1
Therefore:

Substitute the values into the formula.

Divide and note that the meters (m) will cancel each other out.


- 1 s^-1 is equal to Hertz
- Therefore, our answer of 20 s^-1 is equal to 20 Hz

The frequency of the wave is <u>20 Hertz</u>
I think the answer is b. easy to digest.
C. and D. are chemical properties,
