The best answer is Curve 1, since the majority of its brightness-wavelength spectrum is of low brightness and closer to yellow-orange-red. We can also assume a relatively low temperature, which red stars, especially red dwarves, demonstrate as well.
<span>Charge Q = 4.5 µc
Radius of the arc R= 0.55 m
Coulomb constant ke = 8.98755 × 10^9 n • m 2 /c 2
Charge per unit arc length = delta q / delta theta = Q / (pi / 2) = 2Q / pi
=> Delta q = (2Q / pi) delta theta
So the x-component after subtitling the delta q is
E = 2 ke Q / pi R^2 = (2 x 8.98755 Ă— 10^9 x 4.5 x 10^-6) / 3.14 x (0.55) ^2
E = 80.89 x 10^3 / 0.94985 = 85.15 x 10^3 = 85151 N/C</span>

Answer:
Reflection can simply be defined as the reflection of light when it strikes the medium on a plane. Refraction can be defined as the process of the shift of light when it passes through a medium leading to the bending of light. The light entering the medium returns to the same direction.
