A water wave has a frequency of 8 hertz and
a wavelength of 4 meters. What is its speed?

32 m/s

Explanation:

the formula to find speed is to either multiply the wavelength by the frequency or divide the wavelength by the period. Thus the frequency of 8 times the wavelength of 4 would be 32 meters per second.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
