2. Compare and contrast light microscopes, electron microscopes,<br> and atomic force microscopes.
IRINA_888 [86]

Answer:

Answer is the explanation.

Explanation:

A light microscope (LM) is an instrument which uses the visible light and magnifying glasses to examine small objects that are invisible to the naked eye or have finer details than the naked eye allows. However, magnification is not the main problem in microscopy.

Electron microscopy (EM) is a technique for obtaining high-resolution images of biological and non-biological samples. It is used in biomedical research to study the detailed structure of tissues, cells, organelles and macromolecular complexes.

An atomic force microscope is a type of high-resolution scanning probe microscope with a resolution that can be measured in fractions of a nanometer. It was launched in 1986 by Nobel Prize winners Gerd Binnig, Calvin Quate and Christoph Gerber.

A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts
Katen [24]

Answer:

a.)How far from the building does the ball hit the ground?

72 m

b.)How long does it take to hit the ground?

6 s

c.)What is its speed when it hits the ground?

63.48 m/s

Explanation:

When an object is in free fall with no air resistance present or wind acting on it it only is under the influence of gravity. Gravity acts straight down and accelerates the object all the way to the ground. If there is air resistance or a wind force on the object it will have an acceleration that isn't 9.8 m/s^2
