Answer: 3.76 mm
Explanation: The formulae that defines the position of a nth fringe from the center of a double slit interference experiment is given below as
y =R×mλ/d
Where y = distance between the nth fringe and the center
R = distance between slits and screen = 1.71 m
m = position of fringe = 1
d = distance between slits = 0.254 mm = 0.000254m
λ = wavelength of light = 559 nm = 559×10^-9m
By substituting parameters, we have that
y = 1.71×1×559×10^-9/0.000254
y = 0.00000095589 / 0.000254
y = 0.00376m = 3.76 mm

Explanation:
White dwarfs<span> are formed from the collapse of low mass </span>stars<span>, less than about 10 time the mass of the Sun. This </span>star<span> loses most of its mass in a wind, leaving behind a core that is less than 1.44 solar mass. On the other hand,</span>neutron stars<span> are formed in the catastrophic collapse of the core of a massive </span>star.
Option (C) is correct that the majority of the elements on the periodic table are metals.
