This is a video tutorial in the Education category where you are going to learn how to understand polyatomic chemical formulas. When writing the formula using polyatomics, the same cross-over rule applies. 1st identify the metal and non-metal. Then you write the symbols, write the charges, cross-over the charges from top to bottom, remove the charge and simplify the numbers and remove the 1s. for example, iron (II) phospahate. The "ate" ending implies that phosphate is polyatomic. The symbol ...

So you've been using iOS 13 for a little while and noticed your iPhone is pretty slow to charge. Using the 5-watt power adapter out of the box, in the time it used to take your iPhone to charge its battery to 100 percent, your iPhone is stuck at 80% or below instead. That's because Apple introduced a new feature in iOS 13 that slows down charging — but for a good reason.
New technologies in current-generations smartphones allow for much faster charging—Qualcomm Quick Charge 3.0, VOOC Flash Charge, and USB Type-C, for instance, can charge a phone up to 4 times faster than traditional methods. However, the majority of phones on the market still don't support these standards. So for the rest of us, I'll go over an easy tip that can charge any smartphone as much as 25% faster.
In this tutorial we learn how to multiply and simplify square roots. When you multiply square roots, you will first need to put them under one radical. From here, you will need to factor out what you have. Once you find a perfect square, find the square root of it. You can either write these as all separate equations or pull the perfect root on the outside of the other parts of the equation. Do the math until you find what you are left with. From here, you can do basic math to find what's lef...
Using the quadratic formula to solve equations may bring one, two, or no algebraic solutions. The quadratic formula is special to quadratic equations, which can have fractions, radicals, or neverending decimals.

From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's ea...
If you are given an equation of ellipse in the form of a function whose value is a square root, you may need to simplify it to make it look like the equation of an ellipse. Now equate the function to a variable y and perform squaring on both sides to remove the radical. Now simplify the equation and get it in the form of (x*x)/(a*a) + (y*y)/(b*b) = 1 which is the general form of an ellipse. Now you will have the x and y intercepts which are a and b respectively. Using this values graph the eq...
When you need to compute the square root of a number you can do it by breaking it into perfect squares. When you can split the given number into small perfect squares you can cancel out the square root of the expression to the square of the perfect squares. You cannot always write the number inside the square root as a perfect square, but try to write this number as a product of a perfect square and another number. Now you can pull out the perfect square out of the radical and leave the remai...

There's a lot of conflicting information out there when it comes to the best habits for charging a smartphone's battery, so let's clear some of that up right off the bat. Lithium ion batteries (the type used in most modern electronics) start to lose their ability to hold a charge over time, and the two biggest factors that contribute to this are excess heat and overcharging.
Why do we still need to plug in our phones to charge them? Wireless charging exists, and has for quite some time, but most manufacturers don't include it in their devices. When it comes to the Samsung Galaxy S4, you can buy a QI-compatible wireless charging kit, but between the charging pad and the battery cover, you're looking at around $90 or more.
We've all been there. Your phone's either dead or barely hanging on with a few minutes of life left, and you only have a small window of time to charge it before you need to head out.

Connect the positive cable (red) to the positive terminal (+) of the dead battery. Connect the other positive cable to the positive terminal...
In this video, we learn how to use high voltages using the Wimhurst machine. First, you must have a spinning wheel, double ended brushes, collecting combs, leyden jars, adjustable electrodes, and small metal plates. Once you connect all these together, you will notice the brushes on either side are perpendicular to each other and the wheel spin in opposite directions. Spin the wheel and then listen to the sound it makes. The plate will then charge with different electrons and create positive ...
