impulse = F × t
The greater the impulse exerted on something, the greater will be the change in momentum.
impulse = change in momentum
Ft = ∆(mv)
 
        
                    
             
        
        
        
Answer:
The value is   
Explanation:
From the question we are told that 
 The  operating temperature is  
 The emissivity is  
  The  power rating is  
Generally the area is mathematically represented as 
       
Where   is the Stefan Boltzmann constant  with value
 is the Stefan Boltzmann constant  with value  
       
So 
      
      
 
        
             
        
        
        
The property illustrated to each statement is commutative because it shows that for some value of t both statements are equal.

Answer:
Potential difference = 6.0 V
I for 1.0Ω = 6 A
I for 2.0Ω = 3 A
I for 3.0Ω = 2 A
Explanation:
Potential difference (ΔV) = Current (I) x Resistance (R)
The potential difference is constant and equals 6.0 V, hence;
I = ΔV/R
When R = 1.0, I =6/1 = 6 amperes
When R = 2.0, I = 6/2 = 3 amperes
When R = 3.0, I = 6/3 = 2 amperes
<em>The potential difference is 6.0 V and the current is 6, 3, and 2 amperes for a resistance of 1.0, 2.0 and 3.0Ω respectively.</em>
