How Many Faces, Edges And Vertices Does A Triangular Prism Have?
Here we’ll look at how to work out the faces, edges and vertices of a triangular prism.
We’ll start by counting the faces, these are the flat surfaces that make the shape. A triangular prism has 5 faces altogether - 2 triangle faces, as well as 3 rectangular faces.
Next we’ll work out how many edges the triangular prism has, which are where two faces meet. It has 9 edges.
Next we’ll count the corners (the corners). A triangular prism has 6 vertices.

For the full playlist for the faces, edges and Vertices of a whole lot of 3D shapes go to https://www.youtube.com/playli....st?list=PLjbxBzUM6SL

From 1932 to 1972, the United States Public Health Service and the Centers for Disease Control and Prevention operated an extremely unethical medical experiment on the effects of outcomes of untreated syphilis. Hundreds of poor Black men from Macon County, Alabama were enrolled in the study, and treatment for syphilis was withheld from them. Even after antibiotics became available that could cure syphilis, these men were left to suffer from the disease and expose their families to syphilis as well. Today we're learning about the Tuskegee Syphilis Experiment, a shameful example of racism in American medicine, and a tragedy that still impacts how many Black Americans think about healthcare today.

#crashcourse #history #tuskegee

In which John Green teaches you about America's "peculiar institution," slavery. I wouldn't really call it peculiar. I'd lean more toward a horrifying and depressing institution, but nobody asked me. John will talk about what life was like for an enslaved person in the 19th century United States, and how enslaved people resisted oppression, to the degree that was possible. We'll hear about cotton plantations, the violent punishment of enslaved people, the day-to-day lives of enslaved people, and slave rebellions. Nat Turner, Harriet Tubman, and Whipped Peter all make an appearance. Slavery as an institution is arguably the darkest part of America's history, and we're still dealing with its aftermath 150 years after it ended.

In which John Green teaches you about the roots of the American Revolution. The Revolution did not start on July 4, 1776. The Revolutionary War didn't start on July 4 either. (as you remember, I'm sure, the Revolution and the Revolutionary War are not the same thing) The shooting started on April 19, 1775, at Lexington and/or Concord, MA. Or the shooting started with the Boston Massacre on March 5, 1770. At least we can pin down the Declaration of Independence to July 4, 1776. Except that most of the signers didn't sign until August 2. The point is that the beginning of the Revolution is very complex and hard to pin down. John will lead you through the bramble of taxes, royal decrees, acts of parliament, colonial responses, and various congresses. We'll start with the end of the Seven Years' War, and the bill that the British ran up fighting the war. This led to taxes on colonial trade, which led to colonists demanding representation, which led to revolution. It all seems very complicated, but Crash Course will get you through it in about 12 minutes.

So, during times of inflation or deflation, why doesn't the government just set prices? It sounds reasonable, but price ceilings or floors just don't work. Adriene and Jacob explain why. Subsidies, however, are a little different, and sometimes they even work. We'll also explain that. Today you'll learn about stuff like price controls, deadweight loss, subsidies, and efficiency.

In the late 19th and early 20th centuries, Black American Women were struggling with both racism and misogyny as they fought for their rights. Black Women formed clubs and organized to make sure civil and political rights were extended to ALL Black people, not just Black men. These clubs were grass-roots organizations of middle-class women who were often only one generation removed from slavery. Today we'll learn about the origins of these clubs and some of the notable women who drove this movement.

Today on Crash Course Economics, Adriene and Jacob talk about the 2008 financial crisis and the US Goverment's response to the troubles. So, all this starts with home mortgages, and the use of mortgages as an investment instrument. For years, it seemed like the US housing market would go up and up. Like a bubble or something. It turns out it was a bubble. But not the good kind. And the government response was...interesting. Anyway, why are you reading this? Watch the video!

That said, there are some other economic ideas out there, and today we're going to talk about a few of them. So, if you've been aching to hear about socialism, communism, the Chicago School, or the Austrian School, this episode is for you.

How does our knowledge grow? It turns out there are some different ideas about that. Schemas, Four-Stage Theory of Cognitive Development, and Vygotsky's Theory of Scaffolding all play different roles but the basic idea is that children think about things very differently than adults. Hank explains in today's episode of Crash Course Psychology.

Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar and describes why these molecules are so interesting to him.

You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth.

COLLISIONS! A big part of physics is understanding collisions and how they're not all the same. Mass, momentum, and many other things dictate how collisions can be unique. In this episode of Crash Course Physics, Shini sits down to lead us through an understanding of collisions. Plus, she brings along our old friend Sir Isaac Newton.

Social networking is one of the funniest things about Internet, but it's also important to be careful not to hurt other people's feelings. This video showcases a series of situations related to how we can stop cyberbullying. What would you do if someone shared an embarrassing photo of a friend? What if you used a rather unpleasant word while chatting to a friend and he got upset? Would you share personal information with a friend about someone? Virtual is real and words have consequences. Remember that our behavior is critical when it comes to standing against cyberbullying. Be a good friend, not a bystander, respect privacy, your actions can make a difference. And remember, if something bothers you and doesn't feel right, you can always tell an adult about it.
