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 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?
Is feet greater than or less than yards?
3ft = 1yd 1ft = (1/3)yd A foot is one third of a yard, therefore it is less than a yard in length. its less than... just think of a football field
Does low power or high power have a smaller field but magnifies to a greater extent?
hight power
What happens to Field of View when you change from low power to oil immersion high power?
The field of view is inversely related to the magnification power...the greater the magnification, the smaller the field of view
Why is the depth of field greater and the image sharper when a camera lens is stopped down to a larger f-number?
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
What type of microscope uses a magnetic field magnifies up to one million times?
nothing because i dont know
What is an electromagnetic wave affected by?
Electrical field - to a large extent. Gravity - to a lesser extent.
Describe the relationship between size of the receptive field and acuity or discriminative ability of the recetor?
Smaller receptive fields tend to have higher acuity and discriminative ability because they can differentiate finer details or stimuli within their range. Larger receptive fields typically have lower acuity and are more suited for detecting broader or global features.

Do all planets have the same gravitational field strength as earth?
no No the greater the mass of any object the greater the gravitational field. Everything down to the finest speck of dust has a gravitational field.
The greater the mass of an object the greater the objects?
The greater the mass of an object means it causes to have weight in a gravitational field.
What happens to the field of view in a compound in a compound light microscope when the total magnification is increased?
The field of view becomes smaller when magnification increases.

Is a softball smaller than a cricket ball?
Golf balls must weigh less than 45.93g and have a diameter greater than 42.67mm. A cricket ball has to weigh between 155.9g and 163g, and have a circumference between 22.4cm and 22.9. The cricket ball is bigger.
