Hi there! The frequency of a wave is the amount of cycles (or waves) that occur in the given time. So, the answer is D. Normally, the time given is one second, so the frequency unit is Hertz (Hz) most of the time.
Here are some other definitions:
wavelength- the distance from one crest to crest or trough to trough
I hope this helps you! :))
Answer: only Br2.
Justification.
In a chemical reaction the element that gains electrons experiments a reduction in its oxidation state, that is why it is said that it is reduced.
So, to know what element is being reduced you need to calculate the oxidation states of the elements involved.
Here I indicate the oxidation states of each element if the reaction putting them inside parenthesis:
Reactants side Products side
K (0) K (1+)
Br (0) Br(1-)
So, K lost one electron, increasing its oxidation statefrom 0 to 1+, meaning that it is being oxidized.
And, each atom of Br gained one electron, reducing its oxidation state from 0 to 1-, meaning it is being reduced.
Therefore, the answer is that Br2 is the substance being reduced.

Hello there!
In this case, for this chemical equilibrium problem, it turns out possible for us to solve for the equilibrium concentrations by firstly setting up the equilibrium expression:
Thus, by plugging in an ICE chart, in terms of x (reaction extent), we can write:
And could be solved for x as follows:
Therefore, the equilibrium concentrations turn out to be:

Answer:
It is called the superior sagittal sinus.
Explanation:
The superior sagittal sinus which is often called the superior longitudinal sinus) is situated in the human head. It is an unpaired region in the human head around the attached margin of the falx cerebri. It main function is to ensure that blood is removed from the lateral parts of the anterior cerebral hemispheres and transferred to the confluence of sinuses. It also has a triangular cross sectional area and with a left/right lateral angles at its junctions. Therefore, The right answer is the the superior sagittal sinus.
