Answer:
Intensity of the next bright fringe will remain same.
Explanation:
The question is based on Young's double slit experiment, since its about bright fringe, the interference here is constructive.
Young's condition for constructive interference is given by:
dsin
where,
d = slits distance from eachother or width of the slits
= wavelength
n = interferance order
Also, we know that in Young's experiment, the fringe intensity is given by:
where,
= phase difference
Therefore, in absence of phase difference i.e., 
, the intensity of the next bright fringe will not change and it will remain same.
Answer:
20.7 billion = 20.7E9 converting to units of 10
20.7E9 km = 20.7E12 m
t = S /v = 20.7E12 m / 3.0E8 m/s = 6.9E4 s = 69000 s
69000 s = 1150 min = 19.2 hrs
Answer: 21 N
Explanation:
Force=mass x Accceleration
So 21=3x7
