Answer:
1807.56 kJ
Explanation:
Parameters given:
Current, I = 8.9A
Time, t = 4.7hrs = 4.7 * 3600 = 16920 secs
Voltage, V = 12V
Electrical energy is given as:
E = I*V*t
Where I = Current 
V = Voltage/Potential differenxe
t = time in seconds.
E = 8.9 * 12 * 16920
E = 1807056 J = 1807.056 kJ
 
        
                    
             
        
        
        
Answer:
Hyoid
Explanation:
The hyoid is located in the neck area, not the limbs.
 
        
             
        
        
        
Answer:

Explanation:
The magnitude of the electrical force between the two point charges is

where
k is the Coulomb's constant
 is the magnitude of each charge
 is the magnitude of each charge
r = 3.00 m is the separation between the two charges
Substituting the numbers into the formula, we find

 
        
             
        
        
        
Answer:
E=-1.51 eV.

Explanation:
The nth level energy of a hydrogen atom is defined by the formula,

Given in the question, the hydrogen atom is in the 3p state.
Then energy of n=3 state is,

Therefore, energy of the hydrogen atom in the 3p state is -1.51 eV.
Now, the value of L can be calculated as,

For 3p state, l=1

Therefore, the value of L of a hydrogen atom in 3p state is  .
