This physics video tutorial explains how to solve any resistors in series and parallel combination circuit problems. The first thing you need to do is calculate the equivalent resistance of the circuit which you can use to calculate the current flowing from the battery based on ohm's law. Using the current and the voltage drops across each resistor, you can calculate the electric potential at every point in the circuit which will allow you to calculate the current flowing through any resistor. This technique is useful if there's not multiple batteries in different loops of the equation. Keep in mind, the current flowing in two resistors that are in series with each other is the same. The voltage is the same across resistors connected in parallel. This video contains plenty of examples and practice problems including a current division formula for resistors connected in parallel.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

In which John Green teaches you about railroads and some of the ways they changed the world, and how they were a sort of microcosm for the Industrial Revolution as a whole. Prior to the invention of steam-powered railroads, pretty much all locomotion had been muscle-powered. You either walked where you wanted to go or rode on an animal to get where you were going. The railroad changed human perception of time and space, making long-distance travel much faster and easier. Railroads also changed habits, including increasing reading. People needed some sort of distraction to ensure they didn't have to talk to other people on the train. Like any new technology, railroads also scared people. All kinds of fears surrounded rail travel, but over time, people got over them. And the quality of boiler manufacturing improved, so the trains exploded less often, which also made people feel safer.

Rosdely Ciprian, 16, is an exceptional debater and now a judge of the craft. She’s been perfecting her impressive skills since the sixth grade. Her talent has taken her to Broadway, where she debated on stage in the play, “What the Constitution Means to Me,” now streaming on Amazon Prime Video. With debates at the forefront of the presidential election, Ciprian says “always have your sources” and “always let your opponent talk when it's their turn.” Inside Edition Digital’s Leigh Scheps has more. #InsideEdition
What do you know about the country of Mexico? Did you know its official name is the United Mexican States? In All about Mexico for Kids, you and your students will learn a lot about the country's rich history. In fact, lots of really cool remnants of the past, such as ancient cities and pyramids. Lots of them are part of modern cities and towns.
Mexico's terrain is pretty diverse, from high mountains and plateaus to low coastal plains and deserts. Some parts are tropical, so the climate ranges from temperatures typical of deserts to those common to rainforests. The country borders Guatemala and Belize in the southeast and the states of California, Arizona, New Mexico, and Texas in the north. It also touches the Pacific Ocean, the Gulf of Mexico, and the Caribbean Sea.
There are lots of different kinds of animals that live in this country. Mexico actually boasts the most reptiles than any other place in the world. If you visit Mexico, you might find jaguars, pumas, iguanas, lizards, monkeys, or parrots. Of course, it would depend where you are in the country since the habitats are diverse. In the nearby sea or ocean, you might see whales, manta rays, or manatees!
The history of this beautiful country is usually divided into three general periods: early, middle, and recent. The Early period included several ancient societies and civilizations, such as the Olmecs, Mayans, and Aztecs. The Olmecs were the first known society, which existed starting in 1200 BC. The Middle period lasted from around 1519 to 1810. In 1810, which marks the start of Mexico's recent history, a rebel leader and others collaborated to gain Mexico's independence.
We hope you and your student(s) enjoyed learning about this fun country and its history! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

Step right up to Peppa’s circus — just the ticket for little fans!
Grandpa Pig is busy setting up a big tent in the backyard for Granny Pig’s garden party, but Peppa thinks it looks more like a circus tent. What could be better than to put on a circus show during the party? Danny Dog can be the strong man, Suzy Sheep the juggler, and George can wow the crowd as one of the cyclists. And it’s Peppa’s job to make sure the amazing feats go according to plan — she’s the ringmaster, of course!

The process of completing the square for a quadratic expression, equation or, function can be hard to complete. Depending on the instructions you may have to also graph the function once it is in vertex form, or find the x-intercepts using vertex form.
This video goes through three examples with various levels of difficulty.
