Suppose you measure the diameter of the low-power field of view with a ruler and it is 2 mm. If high power provides 10X more mag
nikdorinn [45]

When using high power the diameter of the field of view would be 20 mm.

A microscope is an optical device that is used to view images that cant be seen with the naked human eyes.

It is made up of lens in which  the diameter field of view can be determined.

The diameter of the viewed field in an optical microscope is termed the field number and represents the diameter of the field measured in millimeters (mm) at the intermediate image plane.

From the question, there are two types of field of view

  • <u>Low-power field of view</u>: which is 2 millieters(mm) and
  • <u>High power field of view</u>: which is 10 × low-power field of view

Therefore, to determine the diameter of the field of view when using high power is

10  × 2  =  20mm

What are three kinds of volcanoes? What makes them different?
sashaice [31]

Answer:

Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.

Composite volcanoes are tall, steep cones that produce explosive eruptions.

Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.
