Awave at sea travel with a velocity of 25 m/s. if it has a wavelength of 10 m, what is it’s frequency?

2.5 Hz

Explanation:

Formula for the given question is:

Velocity= frequency X Wavelength.

v= f  X λ.

25 = 10 X f

f= 2.5 Hz

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
