How is the strength of an electric field indicated with electric field lines?
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.
What are synonyms for compass?
range, field, area, reach, scope, limit, extent, boundary
What is apature?
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.
What are symbols that evaluate each field value to determine if it is the same or in between a range values as specified by the criteria?
less than (<) and greater than (>)
What is 3 inches in cups?
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?
