We can reasonably improve a machines ability to do work by reducing the friction between the moving parts of machine.
Angular width is 3 x 10^-3
Let D be the distance between source and screed d the distance between coherent source then for central diffraction maxima,
where λ is wavelength
Given:
λ = 450 nm = 450×10^−9m
d = 0.3x10^−3m, D = 1m
W = 2 x 450×10^−9/0.3x10^−3*1
To Find:
Angular width
Solution: The width of the central maxima is nothing but the difference between the positions of the first two minima. Hence we will use the expression for the position of minima and accordingly obtain the expression of the width of central maxima and secondary maxima
θ = W/D
θ = 2 x 450×10^−9/0.3x10^−3*1/1 = 3 x 10^-3
Hence, angular width is 3 x 10^-3

Answer:
A dictatorship or tyranny.
Explanation:
When you watch the same thing over and over (like a car commercial), then your brain begins to question morals. Like if you see a racing movie you might want to go and race. Or if you see an underage kid illegally driving, you might want to try it too.
