Answer:
width of the slit = a = 0.0935 mm
Explanation:
width of central maximum for single slit diffraction is:
----- (1)
Distance between source and screen = L = 5.5 m
Width of bright band = w = 8 cm
= 0.08 m
λ = 680 nm
Width of the slit = a = ?
Arranging (1) for a
a = 0.0935 mm
Simple, A. None of the other answers make sense so, A.

Answer:
Force = 2802.8 Newton
Explanation:
Given the following data;
Mass = 130 lbs
But, 2.2 lbs = 1.0 kg
130 lbs to kg = 130 * 2.2 = 286 kg
Acceleration due to gravity = 9.8m/s²
To find the force in Newton;
Force = mass * acceleration due to gravity
Force = 286 * 9.8
Force = 2802.8 Newton
