Yard stick
The formula to dertermine the size of an object using mil dots is: Distance (in yards) x height (in mils) ----------------------------------------- = size of the object in yards 1000 to find out the size of the object in inches, simply multiply your answer by 36 (because there are 36 inches in a yard)
A meter stick. (this is true, a meter is the size of a meter or yard stick) although its a little longer than a yard, maybe the size of a simple cabinet or dresser.
yard is an indirect object. There is no direct object.
No, the volume of an object does not change when its size changes. The volume is a fixed measure of the amount of space that the object occupies and is calculated using specific dimensions. Changing the size of the object would involve altering these dimensions but would not impact the volume.
To determine the size of the object, we would need to know the angular size in degrees or radians, as well as the distance to the object. Without this information, it is not possible to calculate the size of the object accurately.
It would help to know the size of a pool. I assume it is not 1 yard!
[object Object]
The size of the object would depend on its distance from the observer. The diameter of the field of view refers to the circular area you can see through a microscope or similar device and not the actual size of an object.
If you had to add material to the object in order to make it bigger, then of course the mass would also get bigger. If the 'object' was the gas in a jar, then all you would have to do to it in order to triple it in size would be to put it in a triple-sized jar and watch it expand. In that case, the mass of the gas would not change at all.
If the size of an object changes, its volume, surface area, mass, and density will also change.
One way to measure the size of an object from an image is to use a known reference object of a standard size in the same image. By comparing the size of the reference object to the size of the object you want to measure, you can calculate the size of the object in the image.
A yard is three times the size of a foot.
