A sound waves frequency is 4hz and it’s wavelength is 8 meters. What is the waves speed

Speed of wave = 32 ms⁻¹

Explanation:

Given data:

Frequency of wave = 4 Hz

Wavelength of wave = 8 m

Speed of wave = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

Now we will put the values.

Speed of wave = 8 m × 4 Hz

          Hz = s⁻¹

Speed of wave = 32 ms⁻¹

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
