Example Input: Aristarchus calculated that the Sun is about nineteen times farther than the Moon; it is actually about 390 times farther than the Moon. Another ancient Greek astronomer, Eratosthenes (276-194 BC), estimated the distance between Earth and Sun to be either 4,080,000 stadia or 804,000,000 stadia. Then 4,080,000 stades is less than 1% of the actual Earth-Sun distance, no matter which definition of a stade one chooses. However, 804,000,000 stadia is between 126 million and 168 million kilometers - a range which includes the actual Earth-Sun distance of (approximately) 150 million kilometers. Earth and the Moon. Background As long as people have looked at the Moon, they have wondered how far away it is from Earth. The average distance to the Moon is 382,500 km. The distance varies because the Moon travels around Earth in an elliptical orbit. At perigee, the point at which the Moon is closest to Earth, the distance is approximately 360,000 km. At apogee, the point at which the Moon is farthest from Earth, the distance is approxi-mately 405,000 km. Distance from Earth to the Moon for a given date can be obtained by asking a local The orbit of the moon around the Earth is not a perfect circle so the distance varies a little. The average distance is around 384,400 kilometers or 230,600 miles. When NASA's Apollo astronauts flew to the moon in the late 1960s and early 1970s, it took them three days to reach the moon and enter orbit after launch. Did you know that the moon is moving away from Earth? It moves away at about 3.8 centimeters per year. SpaceKids on SPACE.com provides simple, straightforward answers to really big cosmic questions. 8 Responses. > 1  the Moon takes an elliptical path around the Earth. The planets make nearly elliptical orbits around the Sun, close enough for reasonable approximations, but the Moon’s Orbit around the Earth is sufficiently influenced by the Sun that it follows a path detectably different from an ellipse. The “Moon ABCs Fact Sheet” lists the Earth's diameter as 12,756 km and the Moon's. diameter as 3,476 km. Therefore, the Moon's diameter is 27.25% of Earth's diameter. An official basketball has a diameter of 24 cm. This can serve as a model for Earth. tennis ball has a diameter of 6.9 cm which is close to 27.25% of the basketball. Distance to the Moon 25 Teacher Page Exploring the Moon -- A Teacher's Guide with Activities, NASA EG-1997-10-116-HQ Purpose To calculate the distance between scale models of Earth and the Moon. Background As long as people have looked at the Moon, they have wondered how far away it is from Earth. The average distance to the Moon is 382,500 km. The distance varies. because the Moon travels around Earth in an elliptical orbit. At perigee, the point at. which the Moon is closest to Earth, the distance is approximately 360,000 km. The full moon rises behind some trees in this photo taken by skywatcher Brad Ervin in Bruswick, Georgia on March 19, 2011, when the moon was closer to Earth than it had been in 18 years. In the former, they found that the Moon was imperfectly blocked by the shadow of the Earth, and that the shadow was roughly 2.5 times the width of the Moon. In the latter, they noted that the Moon was of sufficient size and distance to block out the Sun. Also, since we know the time taken by the Earth to go once around the Sun (P = 1 year), and the distance traveled by the Earth in this process (approximately 2πa, since Earth's orbit is nearly circular), we can calculate the average orbital speed of Earth as v = (2πa)/P. Query: how far is earth from the moon?
Example Output: The average distance between the Earth and the Moon is 382,500 km.

Example Input: A heart attack can happen to anyone, woman or man, young or old. Some people are more at risk because of certain health problems, family health history, age, and habits. These are called risk factors. You can't change some risk factors, like your age, race or ethnicity, or family history. A Month Before a Heart Attack, Your Body Will Warn You With These 8 Signals! - Duration: 6:24. 7ReMix Healthy Tips TV 189,400 views A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks. Although a heart attack is a frightening event, if you learn the signs of a heart attack and what steps to take, you can save a life—perhaps even your own. Many people think that heart attacks are a “man’s problem,” yet heart disease is actually the number one killer of both men and women in the United States. To diagnose a heart attack, an emergency care team will ask you about your symptoms and begin to evaluate you. The diagnosis of the heart attack is based on your symptoms and test results. The goal of treatment is to treat you quickly and limit heart muscle damage. Tests to Diagnose a Heart Attack. ECG . Symptoms of a heart attack may be immediate and intense. More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. Unlike with sudden cardiac arrest, the heart usually does not stop beating during a heart attack. The heart attack symptoms in women can be different than men. What is cardiac arrest? About every 40 seconds, someone in the United States has a myocardial infarction (heart attack). Your heart muscle needs oxygen to survive. A heart attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely (View an animation of blood flow). Several studies have demonstrated that there is seasonal variation in heart attacks. They are most likely to occur in the winter, and least likely to occur in the summer. This is not just true for heart attacks, but also other cardiovascular events. Several explanations have been proposed. Heart attacks may seem like a senior citizen phenomenon, considering that about 82% of people who die of coronary heart disease are at least 65, according to the American Heart Association. But sudden heart problems can occur much earlier in life, too. Every 40 seconds, someone in the United States has a heart attack. 1. A heart attack, also called a myocardial infarction, occurs when a part of the heart muscle doesn’t receive enough blood flow. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle. Query: how does a heart attack occur
Example Output: A heart attack occurs when one or more of your coronary arteries become blocked.

Example Input: The prerequisites for graduate level work in this field are a bachelor's degree and coursework in biology and chemistry. Graduate coursework in anatomy and physiology takes about 18-24 months and a thesis may be required to graduate. Program Levels: Master's degree. Prerequisites: Bachelor's degree, prior coursework in biology. See List of master’s degrees. (source: wikipedia.org) Length of Typical Master’s Degree Programs. The majority of master’s degrees are obtained in the academic disciplines of education and business. If the student already has a baccalaureate degree, these degrees normally can be completed through two years of full-time study. By attending part-time, you may earn your master's degree in three to five years, instead of two. Accelerated Study. You may be able to earn a master's degree in less than two years by taking part in an accelerated degree program. Not all schools offer such programs, and not all types of master's degrees are available in an accelerated format. The University of Southern California's program requires teachers who need certification to complete two 10-week student teaching practicums. Typically, master's degree programs certify graduated teachers to be employed in the state where they earned their degrees. Yes. 1  Pursuing your master’s online is a best bet if you want to advance your career in a field where you already have previous professional experience and you hold an accredited bachelor’s degree. Certain organizations in fields like education, medicine, and engineering may even require their top level employees to have master’s degrees. For example, a student could attain both a bachelor’s degree in Business and an MBA (Master’s of Business Administration) degree in a single five-year program. Master’s degrees have become very popular in recent years and the trend towards getting the degree shows no sign of abating. If you think that a master’s degree is the right choice for you there are numerous options to consider. How long it will take you to complete a master’s degree depends primarily upon which program you want to pursue and whether you want to attend class on a full- or part-time basis. Whether you are still pursuing a Bachelors degree or you are already part of the work force, you may be wondering, “How long does it take to get a Masters degree?” Masters degree programmes are designed to be completed within a year or two, and in an increasingly competitive global job market, an advanced degree, such as a Masters in Finance or Management, may give you the edge you need to stand out to a potential employer. Financial Impact of a Master’s Degree on Salary. 1  Nursing – A bachelor’s degree in nursing earned a median annual salary of $65,470, while a master’s degree in nursing with a nurse practitioner specialization earned $96,460. Many countries in Europe usually offer Masters Degrees which you can complete for only one year, whereas for the same degree in the United States, you would need much longer, typically two years. Another factor that impacts how long does it take to get a Masters Degree is the country in which you choose to obtain your degree. Different educational systems have different durations and credit requirements, therefore in some places you can obtain a degree for half the time that you would need in another place.
