Answer:
The balloon prohibits the flow of air through the air capacitor.
Explanation:
Just like an electric capacitor has an insulator between the plates, the air capacitor has a balloon between the chambers.
 
        
                    
             
        
        
        
Answer:
 Abiotic - sun Biotic- Plants
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Abiotic means non living so the sun is non living. The sun gives us warmth and the ability to survive
Biotic means alive or living- plants are living and give off oxygen and take in carbon to help us live  umm ok 
 
        
             
        
        
        
Answer:
So the conclusion is that in presence of air net force acting downward reduces for feather and hence falls slower than coin. But in absence of air resistance, net downward force is just equal to force due to gravity which is same for both coin and feather and hence they fall down at the same rate.
 
        
             
        
        
        
Displacement s = (u+v)*t/2 (t refers to delta time)
= (0.45 + 2.7)*6/2
= 3.15*3
= 9.45 m
        
             
        
        
        
Answer:
Deltoid Force, 
Additional Information:
Some numerical information are missing from the question. However, I will derive the formula to calculate the force of the deltoid muscle. All you need to do is insert the necessary information and calculate.  
Explanation:
The deltoid muscle is the one keeping the hand arm in position. We have two torques that apply to the rotating of the arm. 
1. The torque about the point in the shoulder for the deltoid muscle,  
 
2. The torque of the arm,  
  
Assuming the arm is just being stretched and there is no rotation going on,
                          = 0
 = 0
                         = 0
 = 0
        ⇒           
                   
Where,
 is radius of the deltoid
 is radius of the deltoid
 is the force of the deltiod
 is the force of the deltiod
 is the angle of the deltiod
 is the angle of the deltiod
 is the radius of the arm
 is the radius of the arm
 is the force of the arm ,
 is the force of the arm ,  which is the mass of the arm and acceleration due to gravity
  which is the mass of the arm and acceleration due to gravity
 is the angle of the arm

 The force of the deltoid muscle is,
