Answer:
y = 80.2 mille
Explanation:
The minimum size of an object that can be seen is determined by the diffraction phenomenon, if we use the Rayleigh criterion that establishes that two objects can be distinguished without the maximum diffraction of a body coincides with the minimum of the other body, therefore so much for the pupil of the eye that it is a circular opening
θ = 1.22 λ/ d
in a normal eye the diameter of the pupils of d = 2 mm = 0.002 m, suppose the wavelength of maximum sensitivity of the eye λ = 550 nm = 550 10⁻⁹ m
θ = 1.22 550 10⁻⁹ / 0.002
θ = 3.355 10⁻⁴ rad
Let's use trigonometry to find the distance supported by this angle, the distance from the moon to the Earth is L = 238900 mille = 2.38900 10⁵ mi
tan θ = y / L
y = L tan θ
y = 2,389 10⁵ tan 3,355 10⁻⁴
y = 8.02 10¹ mi
y = 80.2 mille
This is the smallest size of an object seen directly by the eye
Answer:


Explanation:
(a)
- mass of baby,

- mass of father,

- distance between father and baby,

<u>Now, the gravitational force on baby due to father:</u>



(b)
- distance between baby and Jupiter,

- We have mass of Jupiter,

<u>Now, the gravitational force on baby due to planet Jupiter:</u>



We find that the gravitational force due to Jupiter is considerably greater than the force due to mass of father.
Answer:
Force acts vertically downward
Explanation:
Solution:-
The force is downward. The field lines point from the north pole to the south pole, or left to right. We will apply the use of right-hand rule. Your fingers point in the direction of the current (away from you). Curl them in the direction of the field (to the right). Your thumb points in the direction of the force(downward).
Answer:
The mass is essentially "how much stuff" is in an object. ... Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).
Explanation:
Neptune's largest satellite is Triton, and it revolves in a retrograde orbit, meaning to opposite of Neptune's totation<span />
