What is the speed of a wave that has a frequency of 125 hz and a wavelength of 1.25 meters? express your answer to the nearest whole number

156m\s
Hope this helps! :)

Wave speed is c=λf, where λ is wavelength and f is frequency, so c=1.25*125=156m/s since you’re rounding to the nearest whole number

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Aliquid is an answer i hope this
