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:
I got B,when you subtract 3/5 from NEGATIVE 2/3 it creates a negative 19 over a positive 15.
Answer:
applied force
Explanation:
any force where you push or pull is always applied force.
<h2>Answer: It becomes an Ion
</h2>
When an atom has gained or lost electrons (negative charge), it becomes an ion.
In this sense:
<h2>I
ons are atoms that have <u>
gained or lost</u>
electrons in their electronic cortex.
</h2><h2>
</h2>
If a neutral atom <u>loses electrons</u>, it remains with an excess of positive charge and transforms into a positive ion or <u>cation</u>, whereas if a neutral atom <u>gains electrons</u>, it acquires an excess of negative charge and transforms into a negative ion or <u>anion</u>.
It is then how ions form bonds with other atoms differently depending on the number of electrons they have.
Self productive and it depends on how whom is behaving.
