Answer:
Explanation:
From newton's equation of motion of uniform acceleration 
v = u + at 
where v is final velocity , u is initial velocity , a is acceleration and time is t .
putting the values 
v  =  0 + .5 x 3 x 60  ( time in second = 3 x 60 s ) 
= 90 m /s 
So  , final velocity is 90 m /s . 
 
        
             
        
        
        
The combined amount of kinetic and potential energy of its molecules
        
             
        
        
        
Answer:
The correct answer is "4.443 sec".
Explanation:
Given:
Mass of child,
= 34 kg
Mass of swing,
= 18 kg
Length,
= 4.9 m
The time period of pendulum will be:
T = 
   = 
   =  
  
 
        
                    
             
        
        
        
In a surface wave (like water) the water goes up and down, but the wave travels across (parallel to) the surface.
        
             
        
        
        
Answer:
The following explanatory section gives an explanation of this question.
Explanation:
- This means that perhaps the bubble moves more than a certain duration throughout the calibration breath meter offers the rate as well as oxygenation consumed inside this cell.
- Inside that respirometer, oscillation of something like the bubble gave a technique of multiplying the quantity of oxygenation that is used by the seedlings mostly through cell membrane breathing.
