The Luminosity of a star is proportional to its Effective Temperature to the 4th power and its Radius squared.
        
             
        
        
        
Answer:
8.2 m/s²
Explanation:
m = mass of the block 
μ = Coefficient of kinetic friction = 0.17 
 = Normal force on the block by the ramp
 = Normal force on the block by the ramp 
 = kinetic frictional force
 = kinetic frictional force 
Force equation perpendicular to ramp surface is given as 

Kinetic frictional force is given as 


Force equation parallel to ramp surface is given as 




 m/s²
