Answer:
The diameter of the camera aperture must be greater than or equal to 1.49m
Explanation:
Let the distance separating two objects, x = 6.0 cm = 0.06 m
The distance between the observer and the two objects, d = 160 km = 160000 m
Let ∅ = minimum angular separation between the two objects that the satellite can resolve
tan( ∅) = x/d
Since there is minimum angular separation, tan( ∅) ≈∅
∅ = x/d
∅ = 0.06/160000
∅ = 3.75 * 10⁻⁷rad
For the satellite to be able to resolve the objects,
D ≥ 1.22λ/∅
λ = 560 nm = 560 * 10⁻⁹
D ≥ 1.22 * (560 * 10⁻⁹)/(3.75 * 10⁻⁷)
D ≥ 149.33 * 10⁻² m
D ≥ 1.49 m
Is there any options or just a type up answer?
C) The object would be WHITE.
We call "white light" to the sunlight, but referred to the visible part of spectrum. If the object reflects all the light, it appears as a white object.
The force of friction that is acting on the suitcase is the force that opposes the motion of the suitcase.
<h3>What is friction?</h3>
The force that resists the motion between two bodies in contact. There are some materials that reduces friction such as oil in a car engine reduces friction. In this example, friction creates between the motion of suitcase and with the ground.
So we can conclude that the force of friction that is acting on the suitcase is the force that opposes the motion of the suitcase.

Answer:
Fm is the net force down on the metal in air
Fm / 2 is the net force down on the metal in liquid
Fl is the buoyant force on the metal due to liquid
Fm - Fl = Fm / 2 equating upward and downward forces
Fm / 2 = Fl
The specific gravity of the metal is twice that of the liquid
Note: F = M g = ρ V g since ρ = M / V
