The ones that interact would be Atmosphere, biosphere, and cryosphere. :)
Answer:
<em>A) it transforms a small force acting over a large distance into a large force acting over a small distance.</em>
Explanation:
The hydraulic lever works based on Pascal's law of transmission of pressure through a fluid. In the hydraulic lever, the pressure transmitted is the same.
Pressure transmitted P = F/A
where F is the force applied
and A is the area over which the force is applied.
This pressure can be manipulated on the input end as a small force applied over a small area, and then be transmitted to the output end as a large force over a large area.
F/A = f/a
where the left side of the equation is for the output, and the right side is for the input.
The volume of the displaced fluid will be the same on both ends of the hydraulic lever. Since we know that
volume V = (area A) x (distance d)
this means that the the piston on the input smaller area of the hydraulic lever will travel a greater distance, while the piston on the larger output area of the lever will travel a small distance.
From all these, we can see that the advantage of a hydraulic lever is that it transforms a small force acting over a large distance into a large force acting over a small distance.

9. Color is a property of visible light, the portion of the electromagnetic spectrum that has particular effects on the eyes and brain. Other portions of the spectrum, those observed by radio and X-ray telescopes, must be rendered in false color to make an image. The appropriate choice is the first one:
• radio telescope and X-ray telescope
