Answer:
3.0 x10^-3 J
Explanation:
The potential energy of a spring is given by PE = (0.5)k*x^2  
Where 
K: Spring Constant = 60 N/m
x: displacement of the spring from its equilibrium position = 1cm = 0.01m
Then PE = 0.5(60)(.01)^2 = 0.003J = 3.0 x10^-3 J
 
        
                    
             
        
        
        
Pressure 
= Force/Area 
Area = π(d^2)/4 
 = π(0.4^2)/4
 =0.126 m2 
Pressure 
= 50/0.126 
= 396.825 Pa

Answer:
Mass of object is 0.5kg 
Explanation:
Given the following data;
Force = 6N
Acceleration = 12m/s²
Mass =? 
Force is given by the multiplication of mass and acceleration. 
Mathematically, Force is;
 
 
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making mass (m) the subject, we have;
  
 
Substituting into the equation;
  
 
Mass, m = 0.5kg.
Therefore, the mass of the object is 0.5kg
