If a Substance conducts heat easily then it is considered a good conductor, since the electrons can move freely within the substance.
        
                    
             
        
        
        
Answer:
Angular velocity, 
Explanation:
The mass of the skater, M = 74.0 kg
Mass of each arm,  ( since it is 13% of the whole body and each arm is considered)
 ( since it is 13% of the whole body and each arm is considered)

Mass of the trunk, 

Total moment of Inertia = (Moment of inertia of the arms) + (Moment of inertia of the trunks)


The final moment of inertia of the person:

According to the principle of conservation of angular momentum:

 
        
             
        
        
        
Answer:
use the kinematics equations and solve for time, after that use dleta dx=Vi*delta time
