The answer is A. <span>effective length of the tube
In wind instrument, the effective length is not the actual length of the instrument but only the length that the finger holes manage to cover.
The more holes it managed to cover, the higher frequency of vibration it might able to produce, which lead to higher pitch of the instrument.</span>
        
                    
             
        
        
        
Motor coretex is essential for receiving information that you are moving your legs.
<h3>What is motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe. 
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region. 
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior. 
- For the execution of movements to be precise, coordinated muscle activation patterns are required.
