1-For an ellipse, what is the eccentricity? What is the smallest possible value for
eccentricity? How would you describe an ellipse that has a very small eccentricity?
2-From the information gathered from the planetary orbital eccentricity data table, would you describe the shapes of the planet’s orbits to be very round or very elongated? How did you draw this conclusion?
3-Figure 7 shows a schematic of Earth’s orbit around the Sun. When does perihelion occur for the Earth? What about aphelion? Do you think this perihelion/aphelion effect is the cause of the seasons? Why or why not?
4-Figure 8 shows a schematic of Kepler’s first law. Do you think this representation is accurate for a planet in our Solar System? If you could change this figure to be more accurate for a planetary orbit, how would you change it?
5-Where in a planet’s orbit does it experience maximum orbital velocity, at perihelion or aphelion? Where is its orbital velocity the smallest?
6-The main dividing points of the year are the two solstices (the longest day in summer and longest night in winter) and the two equinoxes (when night and day are equal). These are the starting points of summer, winter, spring and fall, and it is generally assumed that they are equally spaced.
But are they?
Spring equinox in 2003 was on March 21, while fall equinox was on September 22, 184 days later. In 2004, a leap year, spring equinox occurs March 20, and if you count the days, you will see that to get there only takes 181 days more from September 22. The two intervals are not equal!
Equinox positions are on opposite sides of the Earth’s orbit, 180° apart, yet getting through (northern) winter takes Earth 3 days less than getting through summer.
How can that be?
(Interesting note: the above asymmetry was known to the ancient Babylonians, was measured by Hipparchus around 140-130 BC, and was also quoted by Ptolemy.)
7-Halley’s Comet is a short period comet that is visible to us on Earth every 76 years. It is the only known short-period comet that is regularly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime (You may have witnessed Halley’s Comet if you were around in 1986)Would you describe the eccentricity of the orbit to be closer to zero or closer to one? When does Halley’s comet speed up in its orbit and when does it slow down? Would you say that Halley’s comet spends more time closer to perihelion or closer to aphelion?
8-According to Kepler’s third law, there is a relationship between the time a planet takes to revolve around the Sun and its
b. period of rotation
c. distance from the Sun

Names, for example, Ted Bundy, Gary Ridgeway, and the Zodiac Killer have become commonly recognized names because of the horrendous idea of their wrongdoings. One of the most productive chronic executioners in American history is John Wayne Gacy. Nicknamed the Killer Clown due to his calling, Gacy assaulted and killed in any event 33 adolescent young men and youngsters somewhere in the range of 1972 and 1978, which is one of the most elevated realized casualty checks. Gacy's story has become so notable that his violations have been included in mainstream society and TV shows, for example, American Horror Story: Hotel and Criminal Minds. Legal science has, and keeps on playing, a significant part in the comprehending of the case and distinguishing proof of the people in question. John Wayne Gacy's set of experiences of sexual and psychological mistreatment was instrumental in provoking agent's curiosity of him as a suspect. John Wayne Gacy was conceived on March 17, 1942, in Chicago, Illinois. Being the main child out of three kids, Gacy had a stressed relationship with his dad, who drank intensely and was regularly oppressive towards the whole family (Sullivan and Maiken 48). In 1949, a contractual worker, who was a family companion, would stroke Gacy during rides in his truck; in any case, Gacy never uncovered these experiences to his folks inspired by a paranoid fear of reprisal from his dad (Foreman 54). His dad's mental maltreatment proceeded into his young grown-up years, and Gacy moved to Las Vegas where he worked quickly in the rescue vehicle administration prior to turning into a morgue specialist (Sullivan and Maiken 50). As a morgue specialist, Gacy was intensely associated with the preserving cycle and conceded that one night, he moved into the casket of a perished young kid and touched the body (Cahill and Ewing 46). Stunned at himself, Gacy re-visitations of Chicago to live with his family and graduates from Northwestern Business College in 1963, and acknowledges an administration learner position with Nunn-Bush Shoe Company. In 1964, Gacy is moved to Springfield and meets his future spouse, Marlynn Myers. In Springfield, Gacy has his subsequent gay experience when an associate shakily performed oral sex on him (London 11:7). Gacy moves to Waterloo, Iowa, and starts a family with Myers. Nonetheless, after consistently undermining his better half with whores, Gacy submits his originally known rape in 1967 upon Donald Vorhees. In the coming months, Gacy explicitly mishandles a few different adolescents and is captured and accused of oral homosexuality (Sullivan and Maiken 60). On December 3, 1968, Gacy is indicted and condemned to ten years at the Anamosa State Penitentiary. Gacy turns into a model detainee at Anamosa and is allowed parole in June of 1970, an only a brief time after his condemning. He had to move to Chicago and live with his mom and watch a 10:00PM check in time. Not exactly a year later, Gacy is accused again of explicitly attacking a high school kid however the young didn't show up in court, so the charges were dropped. Gacy was known by numerous individuals in his locale to be an enthusiastic volunteer and being dynamic in network governmental issues. His part as "Pogo the Clown" the jokester started in 1975 when Gacy joined a neighborhood "Carefree Joker" comedian club that consistently performed at raising support functions. On January 3, 1972, Gacy submits his first homicide of Timothy McCoy, a 16-year old kid going from Michigan to Omaha. Asserting that McCoy went into his room employing a kitchen blade, Gacy gets into an actual fight with McCoy prior to cutting him over and over in the chest. Subsequent to understanding that McCoy had absentmindedly strolled into the stay with the blade while attempting to get ready breakfast, Gacy covers the body in his slither space. Gacy conceded in the meetings following his capture that executing McCoy gave him a "mind-desensitizing climax", expressing that this homicide was the point at which he "understood passing was a definitive rush" (Cahill and Ewing 349). Just about 2 years after the fact, Gacy submits his second homicide of a unidentified adolescent. Gacy choked the kid prior to stuffing the body in his storeroom prior to covering him (Cahill 349). In 1975, Gacy's business was developing rapidly and his hunger for youngsters developed with it. Gacy frequently attracted youngsters under his work to his home, persuading them to place themselves in binds, and assaulting and tormenting them prior to choking them (Cahill 169-170). A large portion of Gacy's homicides occurred somewhere in the range of 1976 and 1978, the first of this time occurring in April 1976. A significant number of the adolescents that were killed during this time were covered in a creep space under Gacy's home. For the rest of the killings, Gacy confessed to throwing five bodies off the I-55 extension into the Des Plaines River; nonetheless, just four of the bodies were ever recouped (Linedecker 152). In December 1978, Gacy meets Robert Jerome Piest, a 15-year old kid working at a drug store and extends to him an employment opportunity at Gacy's firm. Piest advises his mom regarding this and neglects to restore that night. The Piest family documents a missing individual's report and the drug specialist illuminates police that Gacy would undoubtedly be the man that Jerome addressed about a work. When addressed by the police, Gacy denied any inclusion in Piest's vanishing. In any case, the police were not persuaded, and Gacy's set of experiences of sexual maltreatment and battery provoked the police to look through his home. Among the things found at Gacy's home were a 1975 secondary school class ring with the initials J.A.S., different driver's licenses, binds, attire that was excessively little for Gacy, and a receipt for the drug store that Piest had worked at. Throughout the following scarcely any days, examiners got different calls and tips about Gacy's rapes and the secretive vanishings of Gacy's workers. The class ring was inevitably followed back to John A. Szyc, one of Gacy's casualties in 1977. Futhermore, after inspecting Gacy's vehicle, examiners found a little bunch of strands looking like human hair, which were shipped off the labs for additional investigation. That very night, search canines were utilized to identify any hint of Piest in Gacy's vehicle, and one of the canines demonstrated that Piest had, indeed, been available in the vehicle. On December 20, 1977, under the pressure of steady police reconnaissance and examination, Gacy admits to more than 30 killings and illuminates his legal counselor and companion where the bodies were covered, both in the slither space and the stream. 26 casualties were found in the creep space and 4 in the stream. Gacy is captured, indicted for 33 killings, and condemned to death by deadly infusion. He endeavored a madness request yet was denied, and was executed on May 10, 1994. There were a few scientific pointers that examiners used to attach Gacy to the homicides. A portion of these include fiber investigation, dental and radiology records, utilizing the deterioration cycle of the human body, and facial recreation in distinguishing the people in question. Agents discovered strands that looked like human hair in both Gacy's vehicle and close to the creep space where the bodies were covered. Notwithstanding these hair tests, specialists additionally discovered filaments that contained hints of Gacy's blood and semen in a similar territory. Blood having a place with the casualties was found on a portion of the strands, which would later legitimately attach Gacy to the wrongdoings. The filaments in Gacy's vehicle were examined by legal researchers and coordinated Piest's hair tests. Besides, the hunt canines that verified that Piest had been in Gacy's vehicle showed this by a "passing response", which told specialists that Piest's dead body had been within Gacy's vehicle. Out of Gacy's 33 known casualties, just 25 were ever indisputably distinguished. A considerable lot of Gacy's casualties had comparative actual depictions and were thusly difficult to recognize by absolutely asking the general population. To distinguish the people in question, examiners went to Betty Pat Gatliff, a pioneer in criminological science and facial reproduction. Facial remaking is the way toward reproducing the facial highlights of a person by utilizing their remaining parts. Certain facial highlights, for example, facial structures, nasal structure, and in general face shape can be valuable in recognizing a casualty even long in the afterlife. By utilizing these highlights, and with the assistance of program, criminological specialists can make a picture of an individual's face, which is instrumental in recognizing casualties after their bodies have rotted. Facial reproduction should be possible in a few measurements. Two-dimensional facial recreations is utilized with skull radiographs and depend on pre-passing photos and data. Notwithstanding, this isn't really ideal on the grounds that cranial highlights are not generally noticeable or at the correct scale (Downing). So as to get a practical and more precise portrayal of the casualty's face, a craftsman and a legal anthropologist are typically essential (Downing). Three-dimensional facial remaking is finished by models or high goal, three-dimensional pictures. PC programs can make facial reproductions by controlling examined photos of the remaining parts and use approximations to reproduce facial highlights. These will in general deliver results that don't look fake (Reichs and Craig 491). In some cases, specialists will utilize a strategy called superimposition as a method for facial recreation. Sadly, it's anything but a usually utilized technique, as it expects examiners to have some information about the character of the remaining parts they are managing. By superimposing a photo of a person over the skeletal remaining parts, specialists can check whether the facial highlights line up with the anatomical highlights, permitting them to distinguish a casualty. On account of John Wayne Gacy's casualties, specialists had the option to utilize facial recreation to recognize nine of the bodies found in the creep space.
