It depends how large the object is. But, if it is 2 by 4, most likely the wood sieges more than the glass.
Hope this helps.
        
                    
             
        
        
        
Answer:
a).11.546J
b).2.957kW
Explanation:
Using Inertia and tangential velocity
a).


Now using Inertia an w 

average power=
b).
power=t*w
P=
P=2.957 kW
 
        
                    
             
        
        
        
Metamorphic rock is not formed from A. erosion
        
                    
             
        
        
        
As per energy conservation we know that
Energy enter into the bulb = Light energy + Thermal energy
so now we have
energy enter into the bulb = 100 J
Light energy = 5 J
now from above equation we have
