The three main ideas related to Newton’s Second Law are as follows :
1.Acceleration is the result of
unbalanced forces.
2.A larger force makes a
proportionally larger acceleration.
3.Acceleration is inversely
proportional to mass.
Hope this helps!
        
                    
             
        
        
        
Answer: f = 6.5Hz
Explanation:
Given that the 
Speed V = 65 m/s
Wavelength (λ) = 10m
Wave speed is the product of frequency and wavelength. That is, 
V = fλ
Substitute V and (λ) into the formula to get frequency f 
65 = 10f
Make f the subject of formula 
f = 65/10
f = 6.5 Hz
Therefore, the frequency of this wave is 6.5 Hz?
