Answer: time t = 10s
Explanation:
Given;
Diameter = 8.0cm = 0.08m
Radius r = diameter/2 = 0.08/2 = 0.04m
Cord length d = 6.0m
Angular acceleration = 3.0rads/s2
Time = t
Converting the angular acceleration to linear acceleration 
a = a* × r = 3.0 × 0.04 = 0.12m/s
d = vt + 1/2 (a × t^2)
Initial velocity v = 0, vt = 0 therefore;
d = 1/2 ( a × t^2)
t = √(2d/a)
t = √ [(2× 6)/0.12]
t = 10s
 
        
             
        
        
        
Ans: a = 2.50 m/s^2
Explanation:
First convert the mass in its standard unit i.e. kilogram(kg):
2250 lbs = 1020.583kg
Next use Newton's Second law:
F = ma
Where F = 2552N
m = 1020.583kg
=> a = (2552/1020.583)
a = 2.50 m/s^2
        
             
        
        
        
Answer:
The pressure is  
Explanation:
From the question we are told that 
    The initial pressure is 
    The  temperature is  
     
Let the first volume be  
 Then the final volume will be  
  Generally for a diatomic  gas 
            
Here r is the radius of the molecules which is  mathematically represented as 
     
Where 
 are the molar specific heat of a gas at constant pressure and  the molar specific heat of a gas at constant volume with values 
      
=>   
=>  
=>   ![P_2  =  [\frac{1}{2} ]^{\frac{7}{5} } * 11.2](https://tex.z-dn.net/?f=P_2%20%20%3D%20%20%5B%5Cfrac%7B1%7D%7B2%7D%20%5D%5E%7B%5Cfrac%7B7%7D%7B5%7D%20%7D%20%2A%2011.2)

Explanation:
Both graphs show plotted points forming a curved line. Curved lines have changing slope; they may start with a very small slope and begin curving sharply (either upwards or downwards) towards a large slope. In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity).
