Answer: magnitude and direction
Explanation:They are the two aspects of force that scientists measure
Answers:
a) 10 m
b) time=1.6 s, frquency=0.625 Hz
c) 6.25 m/s
Explanation:
a) If there is a crest at each dock and another three crests between the two docks, and the wavelength 
is the distance between to crests; this means we have 
in 
:
Clearing :
b) This part can be solved by a Rule of Three:
If 10 waves ---- 16 s
1 wave ----- 
Then:
This is the period of the wave
On the other hand, the frequency 
of the wave has an inverse relation with its period :
This is the frequency of the wave
c) The speed 
of a wave is given by the following equation:
Finally:
Answer:
Furthermore, the Pythagorean theorem works when the two added vectors are at right angles to one another - such as for adding a north vector and an east vector.
Wavelength = speed / frequency
(345 m/s) / (20,000 Hz) = 0.017 m
