Answer:
3 order dark fringe
Explanation:
y = Distance from central bright fringe = 204 mm
λ = Wavelength = 400 nm
L = Distance between screen and source = 1 m
d = Slit distance = 6 μm


Order of fringe is 3
So, it is a Dark order fringe
A because that is the answer
Distance = (1/2) (acceleration) (time)²
1.4m = (0.835 m/s²) (time)²
(time)² = (1.4/0.835) s²
<em>time = 1.295 s</em>
I believe the blank would simply be behaviour adaptations. Behavioural adaptations are behaviours that organisms demonstrate to help them better survive and reproduce in a habitat. Hope that helps!!
Answer:

Explanation:
Given that,
The speed of an electromagnetic wave traveling in a transparent nonmagnetic substance is given by :

Where
k is the dielectric constant of the substance.
v is the speed of light in water


So, the speed of light in water is
