Answer:
L = 5.68 10¹⁷ m
Explanation:
The resolution of the telescope is given by diffraction
a sin θ = m λ
Where a is the separation of the linear slits, λ the wavelength, m an integer that determines the order of diffraction
In this case, suppose that the premieres meet Rayleigh's criteria, which establishes that the central maximum of the diffraction of an object coincides with the first minimum of diffraction of the second object. In this case m = 1
sin θ = λ / a
In the case of circular openings, polar coordinates must be used, so the equation is
sin θ = 1.22 λ / D
Where D is the diameter of the lens or tightness. Since the distances are very large and the small angles we can approximate the sine to the radian angle value
θ = 1.22 λ / D
Let's use trigonometry to find the angle. We have the separation of the premieres y = 3.7 10¹¹ m and
tan θ = y / L
θ = y / L
Let's replace
y / L = 1.22 λ / D
L = y D / 1.22 λ
calculate
L = 3.7 10¹¹ 1.03 / (1.22 550 10⁻⁹)
L = 5.68 10¹⁷ m
The answer is A)
Here are some informations you should know:
Uranus is the seventh planet from the sun and the third giant gas planet. It rotates like all planets. But Uranus tilts far to one side. Instead of rotating in an upright position, Uranus rolls along like a bowling ball. Uranus also travels very slowly. Uranus has 27 moons. It takes 84 Earth days to complete one orbit.
Answer:
r=15.53 nm
Explanation:
Lets take electron is in between iron and uranium
Charge on electron
Charge on iron
Charge on uranium
We know that force between two charge
For equilibrium force between electron and iron should be force between electron and uranium
Lets take distance between electron and uranium is r so distance between electron and iron will be 37.5-r nm
Now by balancing the force
So r=15.53 nm
So force
Answer:
Chinese app which is number
Explanation:
A word that would describe their movement would be force. the push is a force that keeps them away.
