A person is standing on the beach counting the waves that come in. The person counts 10.0 waves in 68.0 s. What is the frequency of the ocean waves? HOW DO I FIND THE UNIT FOR THIS QUESTION?

0.14 Hz

Explanation:

We are told the person counts 10 waves in 68 s, from this information we can calculate the frequency , which is defined as the number of oscilations or waves per unit of time. Then:

This is the frequency of the ocean waves. Now, according to the International System of Units (SI), frequency is measured in Hertz (), which is equivalent to .

So, according to this, the frequency of the ocean waves is

it would be kevlar ^^

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
