Given a positive charge the electric field lines are drawn starting from the charge and pointing radially outward, ending in principle at infinity, according to the electric field strength being proportional to the inverse square of distance. From the definition of electric field we know that the modulous of the electric field is greater for smaller distances from the field generating charge. Since the electric field lines point radially outward we consider the density of lines an indication of the strength of the electirc field. If we immagine to trace a circle around the electric field generating charge, of radius slightly greater than the radius of the object which holds the charge and therefore generates the electric field, such circle will be crossed by a number 'n' of lines. The density of lines crossing the cirle will then be the circumference of the circle divided by the number 'n' of lines. For a larger circle we will have a greater circumference, but same number of lines 'n', and therefore a smaller density of lines crossing it, which idicates a lower intesity of electric field for a greater distance from the charge.

Aperture refers to the opening in a camera lens through which light passes to reach the camera sensor. It is measured in f-stops, with a lower f-stop indicating a larger aperture and more light entering the camera. Aperture size also affects depth of field, with larger apertures creating a shallower depth of field and smaller apertures creating a greater depth of field.

we need more information. If you were collecting something in a water bottle then three inches would be smaller then lets say a container full of 3 inches of water the size of a football field. Does this make since?
Low power magnifies to a smaller extent and has a wider field of view, while high power magnifies to a greater extent but has a smaller field of view.
See the answer to "Why do you get a greater depth of field from a smaller aperture"There's also a great article on it at: http://www.uscoles.com/depthoffield.html
As magnification increases, the field of view generally decreases. This is because higher magnification typically focuses on a smaller area in greater detail, limiting the overall visible area in the field of view.
Electrical field - to a large extent. Gravity - to a lesser extent.
The lower magnification provides the largest field of view (FOV). When you increase magnification, the field of view decreases, allowing you to see a smaller area but with greater detail.
No, the gravitational field strength on each planet depends on its mass and radius. For example, Jupiter has a stronger gravitational field than Earth due to its larger mass, while Mars has a weaker gravitational field because it is smaller and less massive than Earth.

When you change from low power to oil immersion high power on a microscope, the field of view decreases. This is because high power objectives have a narrower field of view due to higher magnification, leading to a more detailed but smaller area being visible through the lens.
Starting with a 4x objective allows for a larger field of view and greater depth of field, making it easier to locate and focus on the specimen. Higher power objectives have a smaller field of view and shallower depth of field, which can make it challenging to find and keep the specimen in focus.
High power magnification narrows the field of view, focusing on a smaller section of the slide. This can create the illusion that the overall area of the slide has decreased, when in fact it is just a smaller portion that is being observed in greater detail.
The field of view becomes smaller when magnification increases.
acceleration will be when a force is applied to it. This relationship is described by Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that a larger mass will require a greater force to accelerate at the same rate as a smaller mass.
