The purpose of the scapula to move during arm elevation is increase the range of elevation of the arm.
<h3>What is the importance of movement of the scapula during arm elevation?</h3>
The scapula is an important bone which is found in the shoulder and back region of the body.
The scapula enables and increases the range of motion of the arm with its motions.
During arm elevation, the scapula undergoes an upward rotational motion.
Therefore, the purpose of the scapula to move during arm elevation is increase the range of elevation of the arm.

Answer:
The workdone is 
Explanation:
From the question we are told that
The potential difference is 
Generally the charge on 
is 
Generally the workdone is mathematically represented as
=> 
=>
<span>A motor produces less mechanical energy than the energy it uses because the motor looses some energy to heat.</span>
