The net force on particle particle q1 is 13.06 N towards the left.
<h3>
Force on q1 due to q2</h3>
F(12) = kq₁q₂/r₂
F(12) = (9 x 10⁹ x 13 x 10⁻⁶ x 7.7 x 10⁻⁶)/(0.25²)
F(12) = -14.41 N (towards left)
<h3>Force
on q1 due to q3</h3>
F(13) = (9 x 10⁹ x 7.7 x 10⁻⁶ x 5.9 x 10⁻⁶)/(0.55²)
F(13) = 1.352 N (towards right)
<h3>Net force on q1</h3>
F(net) = 1.352 N - 14.41 N
F(net) = -13.06 N
Thus, the net force on particle particle q1 is 13.06 N towards the left.

- Some people view bacteria specimens with a 100x objective lens in order to see the smallest details.
- Others may use a 10x objective lens for more general purposes, such as examining stained slides or pictures.
- And still others may use a 40x objective lens to gain maximum resolution when viewing images of thick samples.
It is important to choose the appropriate magnification for your needs so that you can properly examine the specimen under study.
<h3>Why is the 100x objective lens necessary to see bacteria?</h3>
- Bacteria must, of course, be viewed at the maximum magnification and resolution possible because to their small size.
- Due to optical restrictions, this is approximately 1000x in a light microscope.
- To improve resolution, the oil immersion method is performed. This calls for a unique 100x objective.

Answer:
, it will sink
Explanation:
The density of an object is given by
where
m is the mass of the object
V is its volume
For the body in the problem, we have
m = 4 kg = 4000 g
Therefore, its density is
And the object will sink in water, because its density is larger than that of water, which is 
. (an object sinks when its density is larger than that of water, otherwise it floats).
Answer:
The correct answers are: Bacteria, Horses, Humans and Mushrooms.
Explanation:
All living organisms are made up of cells. A cell is a microscopic atomic unit and is made up of cytoplasm, one or more nuclei, and a membrane.
They are divided into eukaryotic cells (with nucleus) and prokaryotic cells (they do not have a nucleus).
Depending on the number of cells that living organisms have, they can be classified as single-celled organisms, which are made up of one cell. For example bacteria.
Or they can be multicellular organisms, formed by two or more cells, for example horses.
