Oral route. Many drugs can be administered orally as liquids, capsules, tablets, or chewable tablets. Because the oral route is the most convenient and usually the safest and least expensive, it is the one most often used. However, it has limitations because of the way a drug typically moves through the digestive tract.
Measuring Distances to Stars. Astronomers use several techniques for discovering how far away an object is. The first is called trigonometric parallax and is based on geometry, but it is only good for up to about 500 light-years.
To make things easier, the answer to âhow far is Jupiter from the Sunâ will be simply given for its perihelion and aphelion. At perihelion(closest point), Jupiter is 741 million km or 4.95 astronomical units(AU) from the Sun. At aphelion(farthest point) it is 817 million km or 5.46 AU.
