Educational video for children where they will learn how to calculate the area or surface of the square. The area of the square is equal to multiplying one side by another, meaning the multiplied side by itself. In this video children will practice calculating areas with fun examples. A great resource for Elementary Education.

The President of United States Job | Candidates and Responsibility

Did you ever ask yourself how you become the president of the USA? Well, being the president of any country is a huge responsibility. You need to have a completely balanced nature in making your country's economy strong enough to be called out as a developed nation.

To be on a president's job, you need to acquire certain abilities of leadership in you. Candidates from certain elected parties are upheld to fight for the seat of the president of the USA.

To stand in elections, a person or candidate should be at the age of 35 years old. They should be known as a resident of the USA of almost 14 years. The winning candidate is also the commander in chief of the US army.

Oath taking ceremony of the winning candidate is held in Washington DC. The president of the US resides in a white house where he conducts all his meetings with senior professionals and controls all departments under the US. Meetings with other country officials are also done in the white house.

A person is just allowed to stand in the US presidential elections three times under specific age limitations.

So if you want to know how to become the president of the USA then you must be eligible according to these rules.

Inches, Feet and Yards - Estimating Length | Measurement for Kids | 2nd Grade Math

Install now Kids Academy Talented & Gifted: https://smart.link/5d9b5460c7805

If there is a distance, we find the length of it. We want to know how far a thing is or what’s the length of it. Now length can be measured in three different terms, which are inches, feet, and yard. So, what are these inches, feet, and yards?

These are simply the terms in which we define the length of something. All of them are interrelated with each other.
These terms can be defined in terms of each other.

To put it simply, 12 inches=1 foot and 1 yard= 3 feet. Inch is the smallest term. An inch can be measured in terms of centimeters but that is another term to learn. Simply speaking the distance between your thumb to your knuckle is about 1 inch. The bottle cap is also about 1 inch. So, inch is a very small unit.

These terms help to measure the length and distances. These are very basic measuring terms that the kid must know about in their initial maths lessons.

Why does February have 28 days when all the other months get 30 or 31? The answer is part superstition, part politics, and parts astronomy. (Basically, it's the Romans' fault)

The first quartile of the normal distribution is found at the mean -0.67 times the standard deviation. The third quartile is found at the mean +0.67 times the standard deviation.

The first quartile, the mean, and the third quartile break down the normal distribution into approximately four equal parts each containing about 25% of the distribution.

The problems involving this breakdown of the normal distribution either use the word quartile or talk about 25, 50, or 75 % of the distribution within the question.

Some images used were generated using Geogebra.

This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. It shows you how to identify the chirality centers or carbon atoms with 4 different groups as well as determining the number of stereoisomers using the formula 2^n where n is the number of stereocenters or asymmetric carbon atoms. This video also helps you to identify a pair of meso compounds which are identical to each other and a possess an internal plane of symmetry. It also discusses how to find a pair of enantiomers which are non-superimposable mirror images of each other such as your left hand and your right hand. Enantiomers lack an internal plane of symmetry.

This physics video tutorial provides a basic introduction into pressure and fluids. Pressure is force divided by area. The pressure due to weight of a fluid can be calculated by finding the product of the density of the fluid, the gravitational acceleration and the depth of the fluid. This video contains plenty of examples and practice problems.

The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know that light exists as a wave and why that's really cool!
