Magnification of a microscope is the amount of the visual enlargement of the observed object.
The magnification of a microscope can be increased by changing the lens closer to the object called an objective lens while the ocular lens close to the eyes remain fixed. The magnification is a result of the multiplication of the power of the ocular lens to the objective lens like in the given case:
Magnification= power of ocular lens X power of the objective lens.
The term agglomeration is an economic term used to refer to the phenomenon of firms being located close to one another. There are a number of components we'll explore later in this lesson, but for now, just remember that agglomeration relates to clusters of population or business activity.
Agglomeration, the adhering of particles to each other or to strong surfaces, is a characteristic marvel.
Agglomeration also changes the mass attributes of particulate solids typically to improve things. Bigger particles have less residue, display improved stream conduct, and highlight decreased staying inclinations.
Hence, the right answer for the fill up the blank is "Agglomeration"
