Explanation:
Given that,
Mass = 0.254 kg
Spring constant [tex[\omega_{0}= 10.0\ N/m[/tex]
Force = 0.5 N
y = 0.628
We need to calculate the A and d 
Using formula of A and d
 .....(I)
.....(I)
 ....(II)
....(II)
Put the value of  in equation (I) and (II)
 in equation (I) and (II)


From equation (II)


Put the value of  in equation (I) and (II)
 in equation (I) and (II)


From equation (II)


Put the value of  in equation (I) and (II)
 in equation (I) and (II)


From equation (II)


Put the value of  in equation (I) and (II)
 in equation (I) and (II)


From equation (II)


Hence, This is the required solution.
 
        
             
        
        
        
The basic difference is that the ordinary sources are incoherent that means that the discrete frequencies merge up to give an intermediate between the maximum and minimum frequencies. While the laser is coherent containing the single frequency with maximum amplitude. thus travelling far.
        
             
        
        
        
Answer:
Explanation:
A. Using 
Sinစ= y/ L = 0.013/2.7= 0.00481
စ=0.28°
B.here we use 
Alpha= πsinစa/lambda
= π x (0.0351)sin(0.28)/588E-9m
= 9.1*10^-2rad
C.we use 
I(စ)/Im= (sin alpha/alpha) ²
So
{= (sin0.091/0.091)²
= 3*10^-4

v = v₀ + at
v = final speed, v₀ = initial speed, a = acceleration, t = elapsed time
Given values:
v₀ = 0m/s (starts from rest), a = 9.81m/s², t = 3s
Plug in and solve for v:
v = 0 + 9.81(3)
v = 29.4m/s
