Well, your muscles are made of of the two (most important)  filaments. When one of them moves over the other <span>filaments, the muscles is contracted. If there is an answer choice, I may be able to provide you with a more accurate answer, if this did not already help. ;)</span>
        
             
        
        
        
Solution:
Mass of liquid water and water vapor in the insulated tank initially = 1.4 kg
Temperature = 200 °C 
And 25% of the volume by liquid water is steam.
State 1


 
 (taking the value of
       (taking the value of  and
 and  at 200°C  )
 at 200°C  )

Now quality of vapor

   
Internal energy at state 1 can be found out by

     
     = 856.54 kJ/kg
After heating with the resistor for 20 minutes, at state 2, the tank contains saturated water vapor 
Tank is rigid, so volume of tank is constant.



Now interpolate the value to get temperature at state 2 with specific volume value to get final temperature

    = 369.11° C
Internal energy at state 2

Now power rating of the resistor


   = 1.51 kW
 
        
             
        
        
        
Answer:
I wish I learned what I could do in the real world with the information I learned
Explanation:
 
        
             
        
        
        
In order to answer the question, we need to know what was there before 
AND what was there after.  Is there a reason why you're concealing that 
information ?
While you're at it, you might pass along the answer choices too.
        
             
        
        
        
Well I know that ernest rutherford did the gold foil experiment where he fired alpha particles at gold foil. This experiment founded the nucleus but I don't know if the current model of the atom is based on this.
Cathode ray tube experiments sounds like its to do with electrolysis so i dont think it can be that.
