A Coulomb is the SI unit for charge. It is equal to 6.24 x 10 to the 18th power.
Electric power is voltage times current. Voltage is equal to Joule/Coulomb and an ampere is equal to a Coulomb/Second. Let's take a look at what this SI unit for charge.
A Coulomb is also equal to 1 ampere ( the si unit for current) times 1 second
1C = 1A x 1s
In other words, if the current in a circuit is 1 ampere then 1 Coulomb passes a point each second.
1A = 1C/s

As early astronomers studied the stars, using basic instruments they were able to figure out which day of the year was the longest, which day of the year was the shortest ,and which days had equal sunlight.

Welcome to MooMooMath and Science and what happens on the equinox and the solstice

Because the Earth is tilted at a 23.5 degrees angle and also rotates and revolves around the earth the length of the day varies though out the year
During each equinox, both hemispheres receive almost equal amounts of sunlight
12 hours of daylight and 12 hours of nighttime
The actual day in which both hemispheres receive exactly 12 hours sunlight and darkness is called the equilux and usually occurs a couple days before the march equinox and a few days after the September equinox.
The day of the solstice in either hemisphere has either the most sunlight of the year which is the summer solstice or the least sunlight of the year which is the (winter solstice) except at the equator.

Does the sun always rise exactly due east and due west ?
Remember the sun apears to rise and set due to the movement of the Earth
Actually the sun rises due east and sets due west two times a year. in each hemisphere
In the northern hemisphere on March 20 or 21 depending n the year you have the first day of spring and the sun is directly above the equator. This is called the vernal equinox. Vernal means fresh or new like spring. and the sun will rise due east. Moving forward the sun then starts rising a little more northeast each day until June 20th or 21st depending on the year . This is called the summer solstice and it is the longest day of the year. After the summer solstice sun starts rising less to the north until september 22nd or 23rd which is the autumn equinox. The sun will be directly above the equator again. After this the the sun will rise a little more southern until December 21st or 22nd which is the shortest day of the year called the winter solstice. After this day the sun will rise a little more northern until march 20th or 21st which is the vernal equinox. It takes a year to complete this cycle.
In the southern hemisphere the vernal equinox is september 22 or 23 the summer solstice is December 21 or 22, the autumnal equinox is March 20 or 21 and the winter solstice is June 20 or 21st.

Acceleration is the measure of the change in velocity over time. The change in velocity can be a change in speed, direction or both.

The formula for average acceleration is
Final velocity-Initial Velocity over Time it takes to change

Acceleration is expressed in meters per second squared

What are hybridization and inbreeding? Scientists, animal breeders, and gardeners have long crossed organisms with different traits to produce an organism with unique and maybe superior traits.
In addition, inbreeding is used to preserve traits. For example, Clydesdale horses, and german shepherds are examples of inbreeding.

Pathway of Air Flow
Our journey of oxygen into the lungs and back begins when the brain stem sends a message to the diaphragm which is a muscle under the lungs.
As the diaphragm moves down the lungs expand.

Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.
the voice box (makes sounds when air
passes over the vocal cords)
Epiglottis: the flap of connective tissue that covers
over the larynx during breathing
It stands open during breathing, allowing air into the larynx. During swallowing, it closes to prevent choking on food

From the larynx, air travels to the Trachea which is a rigid tube made of cartilage.
The trachea leads into two tubes called the left and right bronchus
These tubes continue to branch until you reach a tiny air sac called a alveoli
At the alveoli, oxygen diffuses into the capillaries and carbon dioxide diffuse into the alveoli and is exhaled.
This process is repeated over and over again.

Learn the difference between an endothermic reaction and an exothermic reaction.
Endothermic reactions take in energy and might be cold to the touch. Exothermic reactions give off energy and will sometimes be warm or hot to the touch.

The cytoplasm is the fluid found in cells.
Cytoplasm is found in eukaryotic and prokaryotic cells.
The fluid of cytoplasm is called cytosol. It is made up mainly of water
The organelles are found floating in this liquid along with many other items
You can almost think of the cytoplasm as a crowded swimming pool

How is this city like a cell?
They both need to store water and other materials.
Welcome to MooMooMath and Science and organelles and in this video, I will cover the main functions of a vacuole.
Vacuoles store water and waste and other materials in eukaryotic cells. Remember these are cells with membrane-bound organelles and a nucleus.

Vacuoles are storage sacks in plants and animal cells protists but they are not found in
bacterial cells in addition to storing water, vacuoles also store enzymes, waste, and even old damaged organelles.

Learn the diference between saturated,unsaturated, and supersaturated solutions.
Science Standard
When you have an unsaturated solution less solute then the solution is capable of dissolving is mixed in.
With a saturated solution there is so much solute present that if you were to add any more it will not dissolve and excess salt will fall to the bottom of the container.
If you mix in 40 grams of salt at 90 degrees into 100 grams of water.

A supersaturated solution contains more than the maximum amount of dissolved solute then the solvent is able to dissolve at a given temperature.

S8P1.a Develop and use a model to compare and contrast pure substances (elements and compounds) and mixtures.

After passing through the small intestine food travels into the large intestine.
Your large intestine is roughly 9 feet in length but gets it’s name because it has a larger diameter than the small intestine.
Your large intestine is also called the colon.
The large intestine is divided into several sections.
