Answer:
The atomic number is the number of protons in an atom's nucleus.
The atomic number is important, because it determines which element an atom is.
Answer:
It would be "T"
Explanation:
The mass of the satellite doesn´t have anything to do with the time in which the satellite is orbiting the planet, because the gravity of the planet remains the same, in this case as you know the velocity doesn´t depend on mass, so the velocity of orbit will remain the same and the satellite eventhoug twice as heavy or with double the mass will be orbiting at the same rate.
Answer:
a)1984.5nm
b)523mm
Explanation:
A)A destructive interference can be explained as when the phase shifting between the waves is analysed by the path lenght difference
θ=(m+0.5)λ where m= 1,2.3....
Where given from the question the 4th dark Fringe which will take place at m= 3
θ=7/2y
Where y= 567nm
= 7/2(567)=1984.5nm
But
B)tan θ ≈ y/d
And sinθ = mλ/d
y=mλd when m= 1 which is the first bright we have
Then y=(1× 567.D)/d
But the distance from Central to the 4th dark Fringe is 1.83cm then
y= 7λD/2d= 1.83cm
D/d=(2)×(1.83×10^-2)/(7×567×10^-9)
=92221.5
y= (567×10^-9)× (92221.5)
=0.00523m
Therefore, the distance between the first and center is y1-y0= 523mm
