Q: A light year is a measure of distance equal to how far light travels in one Earth year. Because distances across the universe are so large, astronomers use light years. Without light years, discussing the distance between two stars would require the use of large, unruly numbers. Another measure of distance you may come across when learning astronomy is the parsec. It is equal to 3.26 light years. It is another way to simplify the numbers used to calculate and discuss astronomical distances. Using the common physics formula, distance equals rate times time or d = r x t, you can calculate how long a light year is: Light Year = (speed of light) x (one year). Since speed of light is represented by the variable "c", you can rewrite the equation as d = c x t, where d is the distance of a light year, c is the speed of light and t is time. If you want to know the distance of a light year in kilometers, you will need to find the speed of light in kilometers per second. If you want miles, you will need the speed of light in miles per second. You need to know the number of seconds in one Earth year for this calculation. Light in a vacuum travels at a velocity of 186,000 miles per second. This is the equivalent of 299,792 kilometers per second or 670,616,629 miles per hour. Here we will use the velocity in miles-per-second. For this calculation we will use the speed of light, c, equals 186,000 miles per second. This can be rewritten in scientific notation as 1.86 x 105 miles per second. To find the number of seconds in a year, you will do a series of multiplications by conversions units. To convert years to seconds you will multiply the number of days in a year times the number of hours in a day, times the number of minutes in an hour, times the number of seconds in a minute. 1 year x 365 days/year x 24 hours/day x 60 minutes/hour x 60 seconds/minute = 31,536,000 seconds. Again, we can rewrite this large number using scientific notation as 3.154 x 107. Now that you have defined the variables for speed of light and time, you can plug them into the equation d = c x t and solve for the distance of a light year. Replace c with 1.86 x 105 miles per second and time with 3.15 x 107 seconds. d = c x t d = (1.86 x 105) x (3.154 x 107 seconds) d = 5.8 x 1012 or 5.8 trillion miles. If you wanted to calculate in kilometers, simply replace the speed of light with the speed in kilometers per second: 3.00 x 105. The time in seconds remains the same because there is no conversion required. d = c x t d = (3.00 x 105) x (3.154 x 107 seconds) d = 9.46 x 1012 or 9.5 trillion kilometers.
A: Define the light year. Write the formula for distance. Define the speed of light. Calculate the number of seconds in a year. Plug variables into equation and solve. Calculate the distance in kilometers.

Q: Making sure you have a great relationship as friends before moving onto anything else should be considered as much more than simply preparing for your big seduction. If you are friends with someone already, they are going to base your seduction on what they know of you as a person, moreso than the seduction itself. There are friendships in all varying degrees, but many things should be true for all of them. Try to make a regular habit of talking to them. Even if it's small talk, it goes to show that you're interested in them as a person and care about the little things. Make them feel good about themselves. People choose the people in their life usually depending on how they make each other feel. This is true for relationships as much as friendships. You only want to make your move if you think the timing is right. If your friend just heard some bad news and is looking for a shoulder to cry on, a seduction might not be a good idea. The same is true if there is a lack of chemistry between the two of you at the given time. If you think things aren't working at the moment, it's better to wait it out. Try not to wait too long, however. In doing so, you might let someone else take your friend into a relationship, thus ruining your chances at seduction. As a general rule, the more two people of the opposite sex spend together, the more chance there is for something to spark. Before you go in for a direct seduction, sometimes simply asking to hang out often says a lot on its own. If you don't spend time together on a regular basis, you should ask them to meet up. Even if you are just meeting as friends, it's a great way to maximize the chances of something happening. Time in a group is okay, but there is little chance of something special coming out of that. One on one time is different however, as it means the two people are there specifically for time with each other.
A: Be a good friend first. Make sure the circumstances are right. Spend a lot of time together.

Q: Chewing gum stimulates your body's production of saliva, which acts as a natural acid buffer. Chewing gum when you feel heartburn coming on may help. Avoid mint gums, which may actually trigger heartburn. Deglycyrrhizinated licorice (DGL) supplements can help treat heartburn and acid reflux symptoms. Try using them to manage your symptoms whenever they flare up. Make sure you look for deglycyrrhizinated (DGL) licorice. The active ingredient glycyrrhizin can cause serious side effects. When using licorice to treat acid reflux, take 250-500 mg three times daily. You can also make a licorice tea by infusing 1-5 grams of dried licorice root into 8 fluid ounces (240mL) of water. Drink this tea three times daily. Ginger has been used to treat indigestion in traditional Chinese medicine. Indigestion can cause your heartburn or acid reflux symptoms to get worse. Ginger also has other health benefits, such as treating nausea and upset stomach. Take ginger supplements in capsule form or take ginger with meals. Baking soda, or sodium bicarbonate, is a natural antacid that may help neutralize stomach acid that has found its way back into your esophagus. Your pancreas naturally produces sodium bicarbonate to help neutralize excess stomach acid. Try taking baking soda to treat your symptoms. Dissolve teaspoon (3 grams) of baking soda in an 8 fluid ounces (240mL) glass of water. If you are on a low-sodium diet, don't use sodium bicarbonate as it does contain sodium.
A:
Chew gum to reduce your symptoms. Take DGL licorice supplements to reduce the severity of your symptoms. Use ginger to treat relieve indigestion. Try using baking soda as a natural antacid.
