You could attach both springs to the ceiling and hang the same mass from both. The one that stretches less has the larger spring constant value.
        
                    
             
        
        
        
<span>For the answer to the question above.
The pressure (the symbol "P") is the force per unit area applied in a direction perpendicular to the surface of an object. 
This is from least to greatest: 0.3Pa, 16 N/m2, 311 N.m2, 4kPa</span>
        
                    
             
        
        
        
A cable might experience crosstalk, where the electrical signal bleeds from one wire pair to another, creating interference. 
Interference is the process in which two or more waves such as light, sound or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves.
