Answer:
a) Revolutions per minute = 2.33
b) Centripetal acceleration = 11649.44 m/s²
Explanation:
a) Angular velocity is the ratio of linear velocity and radius.
Here linear velocity = 72 m/s
Radius, r  = 0.89 x 0. 5 = 0.445 m
Angular velocity 
          
Frequency 
          
Revolutions per minute = 2.33
b) Centripetal acceleration
                
   Here linear velocity = 72 m/s
   Radius, r  = 0.445 m 
Substituting
    
Centripetal acceleration = 11649.44m/s²
 
        
             
        
        
        
Answer:
Explanation: I think...
Thermal Energy formula Q = mcΔT
Q = Thermal Energy(J)
m = Mass(kg)
c = Specific Heat(J/kg°C)
ΔT = Change in Temperature(°C)
you have to write the equation based on what you are working on
