Answer:
.09 mm
Explanation:
In case of diffraction by single slit with width a the width of central maxima is given below
width = 2 λD/a
where λ is wavelength of light , D is distance of screen , a is width o slit
substituting the given values
14 x 10⁻³ = 
a = .09 mm
b) If a is greater , width of central maxima will be less wide.
I'm pretty sure its simple! I hope this helps

Diffusion is different from osmosis. Diffusion is when a solute passes through a semipermeable membrane inorder to reach equalibrium, while osmosis is water passing through a semipermeable membrane in order to reach equilibrium. Diffusion is when a higher concentration dilutes a lower concentration to reach its most equal state.
The law of conservation of mass states that- "mass<span> in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of </span>conservation of mass<span>, the </span>mass<span> of the products in a chemical reaction must equal the </span>mass<span> of the reactants."
Therefore, the mass of the reactant is the same as the mass of the products.</span>
