Problem: Write an article based on this summary: Add a nut to the hook to see what difference the mass makes. Change the distance to see how it affects the oscillations. Cut off 10 inches (25cm) of the string to see the effects.

Answer: Add a second nut to the hook and bring the pendulum back to where you marked on the paper the first time. When you release the pendulum, start a stopwatch and count the number of oscillations for 1 minute. Repeat the process 5 times, then calculate your average. Notice the difference in the number of oscillations and the average between 1 nut on the hook and 2 nuts on the hook. Add another nut and repeat the experiment to see if even more mass will affect the pendulum's oscillations. Go back to just 1 nut on the hook, bring the string back about 10 inches (25cm), and make a mark on the paper taped behind it so you can repeat the experiment from the same distance. Release the pendulum and count the number of oscillations for 1 minute. Repeat the process 5 times and calculate an average. You may be surprised to learn that the distance (also called amplitude) does not affect the swing rate, or number of oscillations. Try the experiment again from 5 inches (13cm) and find the average number of oscillations to see how much of a difference the distance makes. Slide the look off of the pencil and cut off 10 inches (25cm) of string, tie another loop, and put it back on the pencil. Then bring the pendulum back about 10 inches (25cm) and mark on the paper where you release it from. Repeat the experiment 5 times and find the average number of oscillations to see how the length of the string affects the pendulum. Cut off another 10 inches (25cm) of string to see the difference it makes on the average number of oscillations. The length from which a pendulum is suspended helps determine the speed and regularity of the swings, which is why pendulums have been used to keep time.

Problem: Write an article based on this summary: Stretch first. Get in position. Plant your hands directly below your navel. Tighten your abs.

Answer: This will help your body feel limber and warmed up, making it easier to planche. Proper stretching is a vital part of avoiding preventable injury. A planche is an advanced technique, so you'll need your body in its best order before you attempt it. Touch your toes. Keep your legs as straight as possible. Circle your wrists and hips. Stretch your arms by Crossing one arm over your chest and holding the elbow with the opposite hand; repeat on the other side. Crouch between either push-up bars or parallel bars with your hands grasping the bars on either side. If you don't wish to perform the planche on bars, squat down on the floor with your hands planted on either side of you. Make sure your hands are planted a comfortable distance apart, so you'll be able to support your body adequately. Placement of your hands during a full planche is extremely important to its success. Before you lift yourself up, make sure your hands are planted facing forwards, roughly parallel to where your belly button will be when you lift yourself up. Experiment with different hand grips before you find one that works best for you. Tightening your body will help ensure your body's trunk is firm throughout the planche. Because proper balance is so important during the planche, you need to keep your body straight. Tightening in your abdominal muscles will help keep your body rigid.

Problem: Write an article based on this summary: Remain calm. Search inside your home first. Search in the dark. Use a stinky treat to lure your cat out of hiding. Give your cat some time.

Answer:
Losing track of your cat can be nerve-racking. Keeping calm will help you think clearly and make the most of your search. Stay relaxed and look for your cat as calmly as you can to increase the odds of you finding them. Get a flash-light to help you in your search. Think about where you last saw your cat and start the search there. Keep focused. Search everywhere you can think to look. Search systematically. Look in all the possible hiding spots in a room before moving to the next room. As soon as you notice that you haven't seen your cat for a while, start searching around and inside your house. By searching your house first, you may be able to quickly find your cat and avoid searching beyond your home. Check everywhere, even in tight or small spaces. Look behind and under furniture. If there are areas where you can't reach or see, try using a hair dryer to blow warm (not hot) air into that space. If your cat is there it might flush them out. Ask your family members if they have seen your cat. Try shaking a bag of treats to coax your cat out from its hiding spot. Call out your cat's name. Hearing your voice can sometimes call your cat out. Listen for your cat's voice as you search to help pinpoint its location. Cats are nocturnal, so they are more likely to be active at night. You can try turning out all the lights in your house and sitting quietly, listening for any sounds of movement. If you can't find your cat during the day, you may also want to search again when it is dark outside. You can try shaking a bag of treats, but they may not hear you or be able to resist the temptation. Try finding something very fragrant, like a stinky cheese or a particularly smelly fish. Warm it up in the microwave or oven so that the smell is more pungent and carry it around the house, wafting the smell out with your hand as you search. Your cat may not be able to resist. If you have been searching, having looked everywhere you can think, then you might want to wait for a while. Your cat may have found a hiding spot that you have missed and may just be taking a nap there. If you can't find your indoor cat after intensive searching, try waiting for an hour before expanding the search. If your cat is hiding due to being afraid of something, your search may have caused them to stay in hiding.
