Explanation:
What you have done seems to be correct, what we can do is just add a box into the center. For the 3rd question, we can just draw a box as nothing is happening. That is all!

Answer:
216 m
Explanation:
Assuming a straight line:
Δx = vt
Δx = (12 m/s) (18 s)
Δx = 216 m
Answer: A confederation is a union of sovereign states, united for purposes of common action often in relation to other states.
Explanation:
Confederalism represents a main form of inter-governmentalism, this being defined as any form of interaction between states which takes place on the basis of sovereign independence or government.
Answer:
Frequency = 1,550Hz
Explanation:
To solve this we can use the equation:
(frequency = velocity/wavelength).
We are given the information that the wavelength is 22cm and the speed is 340m/s. The first step is to make sure everything is in the correct units (SI units), and to convert them if needed. The SI Units for velocity and wavelength are m/s and m respectively. This means we need to convert 22cm into meters, which we can do by dividing by 100, (as there are 100cm in a meter). 22/100 = 0.22m
Now we can substitute these values into the formula and calculate to solve:
Simplify to 3 significant figures:
f = 1,550Hz
(Which I believe is just below a G6 if you were interested)
