Answer:
52 Hz
Step-by-step explanation:
We can divide the speed by the wavelength to find the number of waves propagated in one second:
(130 m/s)/(2.5 m/wave) = 52 waves/s
The SI unit of frequency is the Hertz, equal to one cycle per second.
The frequency of this wave is 52 Hz.
_____
<em>Additional comment</em>
The use of the unit Hz to signify frequency was adopted in 1933, but did not replace the unit "cycles per second" (CPS) until a number of years later.

Est Answer: say the numbers<span> are x and y......and y being the bigger </span>number<span> ... </span>If<span> the </span>ratio<span> is 5:3, then </span>difference<span> between </span>ratio<span> = 5-3 = 2 ... Substituting this x = 5y/3 in equation x-y=</span>18<span> we </span>get<span> ... therefore x = 5 * 27/</span>3 = 5<span>*9 = 45 .... One </span>number<span> is 5 more than another. </span>their<span> sum is 53 what are the </span>two numbers<span>?</span>
