Answer:
Fixed mindset 
Explanation:
Mindset could be explained as an individual's psychological state which often transcends into how we perceive challenges, what we can do and what we can't.

Answer:
<u>$50</u>
<u>Explanation</u>:
In the production function, Q = K0.5L0.5, 
K denotes the fixed input in the short run. 
First, we calculate the total cost:
Cost of Capital= 25 x $1 = $25
Cost of Labor (for a start 25 workers are used)= 25 x $1 = $25
Total= $50
Since the price of the solar panels is $100, substrating from the total cost $50 (100-50) we get $50 profit per unit of solar panel.
 
        
             
        
        
        
Probably production function
