Problem: Write an article based on this summary: Connect a USB cord to the controller. Connect the USB cord to the PS4. Press the "PS" button.

Answer: The USB port is located on the top of the controller below the triangle shaped light bar. The USB ports are next to the disk reader on the front of the console inside the slot. It's the button with the PlayStation logo located in the center of the controller between the two joysticks. This will pair the controller with the PS4. Once the controller is paired, you can turn on the PS4 by pressing the PS button on the controller.

Problem: Write an article based on this summary: Move around. Go to the gym. Do yoga or other stretching. Take a power nap, if allowed. Take a shower.

Answer: If you are sitting down and working, try to stand up every 5-10 minutes. Do a few jumping jacks or a dance to your favorite song if you need a burst of energy to jump-start your productivity. Going for a short walk down the hall (or, better yet, outside) also helps. If you consistently feel sleepy in the middle of the day or just after lunch, try getting in a midday workout. Exercise, though it expends energy, also boosts energy. Hit the gym during your lunch hour. Go for a brisk walk outside. Walk around the building. Walk some flights of stairs to the fourth-floor office and back. Take some laps around the field house at your high school. Pop by your boss's office instead of sending a message. Find an office workout routine if you cannot leave work to exercise. This may include push-ups, chair sits, lunges, and sit-ups. Just remember to close the blinds to your office window! Yoga, while calming, is also rejuvenating. Doing a few yoga poses that promote energy when you feel tired can give your body an energy boost. Here are a few poses to try: Camel pose: while on your knees, arch your back so that your heart and your chest are open forward. With your feet flexed and your toes grounded, reach back and hold your ankles with your hands, and let your head fall back to stretch your neck. Warrior Two: do a deep lunge, with the forward knee straight above the ankle and the foot facing the wall in front of you. The back leg should be extended with the leg straight and the foot sideways, perpendicular to the forward foot. Extend both arms out in the directions of your legs and look forward, over your extended arm and forward foot. Be sure to alternate sides. Chair pose: stand with your feet flat on the floor, shoulder-width apart. Then sink down into a squat, as though you were going to sit in a chair. Be sure to keep your back completely flat. Raise both arms up over your head, shoulder-width apart, palms facing each other but not touching and fingers spread. Hold for several seconds, then stand up. Rest and repeat several times. Ward off extreme fatigue by taking a short nap. Evaluate whether this option is appropriate for you based on where you are. This is obviously not an option if you are driving, and it may not be an option if you are at work. The nurse's office at school sometimes encourages a lie-down, with the advantage that you have someone to nudge you awake before your next period. Try to sleep for at least 20 minutes. Try other methods of staying awake to rouse yourself fully after you wake from your nap so you don't feel even more sleepy. Taking a shower is sometimes even better than taking a nap. It can refresh you and make you feel like you are ready for more work. A cold shower may be necessary if you are extremely tired. The temperature changes from taking a warm shower then stepping out into cool air can also help you wake up.

Problem: Write an article based on this summary: Choose your color scheme. Pick a theme. Decide on the layout. Consider the paint finish. Consider the room that you are painting.

Answer: Unless you are painting a mural, you might want to limit your colors to two or three; this includes the base/background color of the wall. If you make your wall too busy, it will draw attention away from the rest of your room. Here are some color ideas to get you started: If you want a more subtle look, use two different shades for your wall and design. For example, you can paint your wall a dark blue, and stencil on some bird silhouettes in light blue. If you want a bolder look, use contrasting colors. For example, you can paint your wall a fresh, spring green, and some leaf and branch outlines in bright white. You can also paint colored designs. For example you could start with a dark brown or black branch on a white wall. Then, you could add some light pink cherry blossom flowers to the branch. Most walls with designs have a specific theme to them. The easiest designs to paint are silhouettes or outlines. They will be just enough to add some interest and movement to your wall, but they won't be so busy as to detract attention from the rest of your room. Here are some common themes: Nature-related, such as branches, leaves, and birds Abstract designs, such as scrolls and damask Do you want your design to cover the entire wall, or just a small patch? How you arrange the design is important. Here are some ideas to get you started: If you are covering your entire wall with the design, consider a grid or checked pattern. If you are covering just a small patch, consider making the patch more asymmetric than asymmetric. If you are using both large and small shapes in your design, try to place the larger designs more towards the center of the patch, and the smaller designs towards the edges. Most acrylic paints will have a glossy, satin/semi-gloss, or matte finish. Most walls will have a satin/semi-gloss or matte finish. If you use the same finish for both your wall and your design, you will get a more uniform result. The design will blend into the wall, and look like it is part of it. If you use contrasting finishes (such as a glossy design on a matte wall), you will get a bolder result. The design will contrast with the background/wall, which can create a very interesting result. Some designs are better suited to certain rooms than other designs. For example, you might consider a more energized design in a room that sees a lot of activity, such as a family room. Bedrooms are generally a place of rest, so a more peaceful design might do better there. Here are some ideas to get you started: For a fancy dining or family room, consider using dark, rich colors. Use ornate designs, such as scrolls and damask. For a kitchen, consider using something bright and open. You can also paint some food-related designs, such as grapevines or citrus. For a bedroom, use colors that you find peaceful. These can be cool blues and purples, refreshing greens, or even pastels. Consider using something organic for the design, such as long, sweeping curves, leaves, flowers, or branches.

Problem: Write an article based on this summary: Determine which isotopes are in the sample. Determine the relative abundance of each isotope in the sample. Multiply the atomic mass of each isotope by its proportion in the sample. Add the results.

Answer:
Chemists often determine the relative proportions of isotopes in a given sample by using a special tool called a mass spectrometer. However, at student-level chemistry, this information is often provided for you on school tests, etc., in the form of established values from scientific literature. For our purposes, let's say we're working with the isotopes carbon-12 and carbon-13. Within a given element, different isotopes appear in different proportions. These proportions are almost always expressed as percentages. Some isotopes will be very common, while others will be very rare - at times, so rare that they can barely be detected. This information can be determined through mass spectrometry or from a reference book. Let's say that the abundance of carbon-12 is 99% and the abundance of carbon-13 is 1%. Other carbon isotopes do exist, but they exist in quantities so small that, for this example problem, they can be ignored. Multiply the atomic mass of each isotope by its percent abundance (written as a decimal). To convert a percentage to a decimal, simply divide it by 100. The converted percentages should always add up to 1. Our sample contains carbon-12 and carbon-13. If carbon-12 makes up 99% of the sample and carbon-13 makes up 1% of the sample, multiply 12 (the atomic mass of carbon-12) by 0.99 and 13 (the atomic mass of carbon-13) by 0.01. A reference book will give percent proportions based on all the known amounts of an element's isotopes. Most chemistry textbooks include this information in a table at the end of the book. A mass spectrometer can also yield the proportions for the sample being tested. Sum the products of the multiplications you performed in the previous step. The result of this addition is the relative atomic mass of your element - the average value of the atomic masses of your element's isotopes. When discussing an element in general, and not specific isotopes of that element, this value is used. In our example, 12 x 0.99 = 11.88 for carbon-12, while 13 x 0.01 = 0.13 for carbon-13. The relative atomic mass of our example is 11.88 + 0.13 = 12.01.
