Question 2 of 5 What is the frequency of a wave that passes a given point 57 times in 3.0
seconds?
O A. 0.053 s
B. 19 Hz
C. 171 Hz
O D. 60 s
SUBMIT

Frequency=?,number of oscillation=57,time=3.

There are two ways to go about this

You can other use this formula: frequency=number of oscillation/time.

which is 57/3=19Hz.

OR.

You can use this formula:Period is time/number of oscillation.. which is..

3/57=0.053.

and frequency is 1/TThe "T" stands for period.

So since frequency is 1/T then it will be 1/0.053=18.8~19Hz..

The answer is option B.

Thank you for the question I hope it helps you

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
