What is the wavelength of an earthquake wave if it has a speed of 15 km/s and a frequency of 9 hz?

To calculate the wavelength, the formula to use is:

Wavelength = Speed / Frequency

Wavelength = 15 km/s / 9 Hz

Wavelength = 1.6666666667 or 1.67 km

The standard unit for Wavelength is meter so the final answer would be 1666.67 meters

Ifeel like lily and ledbetter had a fair pay act just because it was necessary especially at those times

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.
