Answer:
The cost of energy is $ 0.34. 
Explanation:
The energy is the capacity to do work. 
The energy is a scalar quantity and its SI unit is Joule. 
The commercial unit of energy is kWh. 
Cost of 1 kWh energy = $ 0.17 
energy loss by standard window is 2 kWh . 
So, the cost of lost of energy is 
Cost = $ 0.17 x 2 = $ 0.34 
 
        
             
        
        
        
The simplest answer would be "acceleration due to gravity." 
The exact value of this acceleration changes depending on which planet your on (for example).
        
             
        
        
        
Answer:
