Answer: 
The correct answer is option b, 0.3m/s
Step by Step solution:
The relation between speed, wavelength and frequency of a wave is given by the following equation:  
Speed = Wavelength x Frequency
Substituting the values in above equation we get –  
= 3  x 0.1  
= 0.3 m/s  
 
        
                    
             
        
        
        
The type of glial cells are particularly at risk from the disease are the Schwann cells.  This disease is caused by a bacterium, Corynebacterium diphtheriae, and is caused when the bacteria releases a toxin, or poison, into a person's body. The Schwann cells produces insulating myelin sheath that covers the axons of many neurons. These cells may suffers immune or toxic attacks with diphtheria infection.
