INPUT ARTICLE: Article: Though distance is different than displacement, resultant displacement problems will specify how many "feet" or how many "meters" an object has traveled. You will use these units of measurement to calculate displacement, or how far out of position the object is based on its original point. The resultant displacement formula is written as: S = x+y. "S" stands for displacement. X is the first direction that the object is traveling and Y is the second direction that the object is traveling. If your object only travels in one direction, then Y = 0. An object can only travel in two directions maximum, since moving along the north/south or east/west axes will be considered neutral movement. Use a ruler to make straight lines from point to point. Also remember to connect your starting point to your end point using a straight line. This is the displacement we will be calculating. For example, if an object travels east 300 feet and north 400 feet, it will form a right triangle. AB will form the first leg of the triangle and BC will form the second leg. AC will form the hypotenuse of the triangle, and its value will be the amount of the object's displacement. In this example, the two directions are "east" and "north." Now that you know the two directions your object is traveling in, input the values into their respective variables. For example, x = 300 and y = 400. Your formula should look like this: S = 300 + 400. Square 300 and 400 first, then add them, and then find the square root of that sum. For example: S = 90000 + 160000. S = 250000. S = 500. You now know that displacement is equal to 500 feet.

SUMMARY: Use the resultant displacement formula when units of distance are used to specify your initial and final location. Connect the points based on order of movement and label them from A-Z. Input the direction values for x and y. Compute the formula using the order of operations.

In one sentence, describe what the following article is about: Rotary veneers are what plywood is made out of and generally produce an appearance that many people don't like. However, they can also come in larger sheets and may be the only option for very large projects. Sliced veneer looks like normal lumber, and allows you to get really beautiful grain detail. You can get random sets of veneers, or you can get book-matched sets. In book matched sets, you get the pieces that were cut one next to the other, so that the grain patterns match up. This can be used to create beautiful designs. However, unmatched sets may look more "natural". You can get veneer sheets that have adhesive already applied to one side. These are the easiest to place. If you get regular veneer, however, you'll need to use the application method discussed in the other section. These are generally applied just like a sticker, but you should read the included instructions to see if that particular manufacturer requires special steps. Veneers are attached to a substrate (or base material). Usually this is either another wood (if you are veneering, for example, panels on doors or cabinets) or it is a cheaper material altogether, such as MDF. These man-made materials are probably the best option, since they usually allow you to save the most money. You can use yellow or carpenter's glue if you want to. If you live in a very dry environment with little humidity, these will work perfectly fine. If you live in a humid environment, however, these glues can cause your veneers to wander. It's better to use a proper veneering glue. Many other methods of veneering use these glues. Be wary of those methods, especially if you live in a humid environment.
Summary: Choose a rotary vs sliced veneer. Choose a random or book-matched veneer. Choose your application method. Choose your substrate. Choose a glue.

There are two main types of Roku, both of which will require your TV to have at least one HDMI port to use: Roku Player Resembles a box. Comes with several cables. Roku Stick Resembles a flash drive (memory stick). Comes with at least one power cable. All HDTVs have at least one HDMI port; the HDMI port resembles a trapezoid, and can often be found on the back of the TV (though some TVs have the HDMI port(s) on the side). Depending on your Roku type, this process will vary slightly: Roku Player Plug one end of the HDMI cable into the back of the Roku Player's box, then plug the other end into the HDMI port on the back or side of your TV. Roku Stick Plug the HDMI connector on the end of your Roku Stick into the HDMI port on the back or side of your TV. Most HDTVs have more than one HDMI port. If your TV doesn't have an HDMI port, you cannot use a Roku Stick with your TV; you may be able to buy an HDMI to Component adapter if your TV has component (e.g., red, white, and yellow) ports. On TVs which have more than one HDMI port, you'll see a number next to the port into which you plugged the Roku. This number may be written as "HDMI 1", HDMI 2", and so on. Your TV may also just have the ports labeled with individual numbers (e.g., "1", "2", etc.). Both the Roku Player and the Roku Stick require connection to a power source (e.g., an electrical outlet): Roku Player Plug one end of the included power cable into the back of the player box, then plug the other end into an electrical outlet. Streaming Stick (model 3800 and down) Plug one end of the included power cable into the back of the stick, then plug the other end into an electrical outlet. If your Roku Stick has a USB power cable and your TV has a USB port, you can instead plug the USB cable into your Roku Stick and your TV. Streaming Stick+ (model 3810) Plug one end of the included power cable into the side of the stick, then plug the other end into an electrical outlet. If your Roku Stick has a USB power cable and your TV has a USB port, you can instead plug the USB cable into your Roku Stick and your TV. Turn on your TV, then press the Input, Video, or Source button on the remote (or the TV) and select the HDMI slot into which the Roku Stick is inserted. This will open the Roku's setup screen, from which point you can begin setting up your Roku.

One-sentence summary -- Determine your Roku type. Plug the Roku into your TV's HDMI port. Note the HDMI port's number. Attach the Roku to a power source. Switch to the Roku's input.

INPUT ARTICLE: Article: It's the app with a green chat bubble on your home screen or in the app drawer. Because WhatsApp has no built-in Log Out button, you'll have to sign out by deleting the app's data from your device. To make sure you don't lose your chats, back them up to your Google account.
