Answer:
The value of spring constant is 266.01 
Explanation:
Given:
Mass of pellet  kg
 kg
Height difference of pellet rise  m
 m
Spring compression  m
 m
From energy conservation law,
Spring potential energy is stored into potential energy,
   
Where  spring constant,
 spring constant, 
   
   
    
 
Therefore, the value of spring constant is 266.01 
 
        
             
        
        
        
Answer:
the net toque is τ=8.03* 10⁻⁴ N*m 
Explanation:
Assuming the disk has constant density ρ, the moment of inertia I of is 
I = ∫r² dm 
since m = ρ*V = ρπR² h , then dm= 2ρπh r dr
thus
I = ∫r²dm = ∫r²2ρπh r dr =2ρπh ∫r³ dr = 2ρπh (R⁴/4- 0⁴/4)= ρπhR⁴ /2= mR²/2
replacing values
I = mR²/2= 0.017 kg * (0.06 m)²/2 = 3.06 *10⁻⁵ kg*m²
from Newton's second law applied to rotational motion
τ= Iα , where τ=net torque and α= angular acceleration 
since the angular velocity ω is related with the angular acceleration through
ω= ωo + α*t → α =(ω-ωo)/t =  (21 rad/s-0)/0.8 s = 26.25 rad/s²
therefore
τ= Iα= 3.06 *10⁻⁵ kg*m²*26.25 rad/s² = 8.03* 10⁻⁴ N*m 
 
        
             
        
        
        
Hi!Schrodinger equation is written as HΨ = EΨ, where h is said to be a Hamiltonian operator.
