Answer:
The method to determine whether a string contains a value that can be converted to a specific data type before it is converted to that data type
Explanation:
 
The Java string includes () method to check whether a particular sequence of character is the part of given sub string or not.
One string contain another string in Java or not. 
The indexof() to check the string and substring in java 
Hence java string include () method to check  whether a string contains a value that can be converted to a specific data type before it is converted to that data type
 
        
             
        
        
        
Answer:
distance and time
Explanation: the farther you go and how much time it will take you
 
        
             
        
        
        
Answer:
The time taken is  
Explanation:
From the question we are told that 
   The length of steel the wire is  
    The  length of the  copper wire is  
     The  diameter of the wire is  
      The  tension is  
       
The time taken by the transverse wave to travel the length of the two wire is mathematically represented as 
               
Where   is the time taken to transverse the steel wire which is mathematically represented as
 is the time taken to transverse the steel wire which is mathematically represented as 
          ![t_s  = l_1 *  [ \sqrt{ \frac{\rho * \pi *  d^2 }{ 4 *  T} } ]](https://tex.z-dn.net/?f=t_s%20%20%3D%20l_1%20%2A%20%20%5B%20%5Csqrt%7B%20%5Cfrac%7B%5Crho%20%2A%20%5Cpi%20%2A%20%20d%5E2%20%7D%7B%204%20%2A%20%20T%7D%20%7D%20%5D)
here   is the density of steel with a value
 is the density of steel with a value  
    So 
       ![t_s  = 31 *  [ \sqrt{ \frac{8920 * 3.142*  (1*10^{-3})^2 }{ 4 *  122} } ]](https://tex.z-dn.net/?f=t_s%20%20%3D%2031%20%2A%20%20%5B%20%5Csqrt%7B%20%5Cfrac%7B8920%20%2A%203.142%2A%20%20%281%2A10%5E%7B-3%7D%29%5E2%20%7D%7B%204%20%2A%20%20122%7D%20%7D%20%5D)
       
  And 
          is the time taken to transverse the copper wire which is mathematically represented as
 is the time taken to transverse the copper wire which is mathematically represented as 
       ![t_c  = l_2 *  [ \sqrt{ \frac{\rho_c * \pi *  d^2 }{ 4 *  T} } ]](https://tex.z-dn.net/?f=t_c%20%20%3D%20l_2%20%2A%20%20%5B%20%5Csqrt%7B%20%5Cfrac%7B%5Crho_c%20%2A%20%5Cpi%20%2A%20%20d%5E2%20%7D%7B%204%20%2A%20%20T%7D%20%7D%20%5D)
here   is the density of steel with a value
 is the density of steel with a value  
  So 
       ![t_c  = 17 *  [ \sqrt{ \frac{7860 * 3.142*  (1*10^{-3})^2 }{ 4 *  122} } ]](https://tex.z-dn.net/?f=t_c%20%20%3D%2017%20%2A%20%20%5B%20%5Csqrt%7B%20%5Cfrac%7B7860%20%2A%203.142%2A%20%20%281%2A10%5E%7B-3%7D%29%5E2%20%7D%7B%204%20%2A%20%20122%7D%20%7D%20%5D)
       
So  
    
     
     
 
        
             
        
        
        
Answer:
Answer:
Option B 
Explanation:
Option B talks about how the frequency of the wave increases the shorter it's wavelengths
 
        
             
        
        
        
My guess for this one would be; 400 N
My reasoning would be; it starts at 0 on both X and Y, if you need to get to 1.00 meters thats 4/4. 1/4 of 1.00 is .25, and on .25 its on 100 so multiply it by 4 to make 1.00 and you get 400 N
