What is the speed of a wave with a wavelength of 0.60 m and a frequency of
240 hz?
o a. 400 m/s
o b. 144 m/s
o c. 1,440 m/s
od. 40 m/s

Answer isB.144m/s.

hope it will help u.

144 m/s

Explanation: Wave speed is simply the product of frequency and wavelength

Solution:

v= 240 Hz x 0.60 m

= 144 m/s

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
