Answer:
Elastically 
Explanation:
A rock that has deformed Elastically under stress keeps its new shape when the stress is released.
In elastic deformation the original shape of the object is regained when the stress is removed. Whereas in plastic deformation the original shape is parmanently deformed with the application of stress. 
 
        
             
        
        
        
No. You cannot rule out the battery even after the open circuit voltage measurement. The open-circuit voltage may not have changed but the battery's internal resistance may have greatly increased.
 
        
             
        
        
        
Answer:
v = 20.31 m/s
Explanation:
p = mv -> v = p/m = 32,500 kg*m/s / 1,600 kg = 20.31 m/s
 
        
             
        
        
        
Answer:let initial velocity u=14m/s
Final velocity v=20m/s
Time taken t=30
Acceleration =a
V=u +at
a= (20-14)/30
a=0.2m/s^2
Explanation:
Acceleration is the change in velocity with respect to time.
 
        
             
        
        
        
Answer:
The value  is  
Explanation:
From the question we are told that 
    The number of turns is  N  =  1000
     The length is  L =  50 cm =  0.50 m   
     The radius is  r =  2.0 cm  =  0.02 m 
      The current is I  =  18.0 A 
     
Generally the magnetic field is mathematically represented as 
          
Here  is the permeability of free space with value
 is the permeability of free space with value  
      
So
