Case Study in Determining Practice Schedule
Mohammed was the newly appointed coach of the high school track team. He had plenty of experience as a runner, having
competed at the international level, but very little experience in performing or coaching field events, he was concerned about his lack
of knowledge of weight events, particularly the shot put. he had read books about the skill but wanted to take a scientific approach
that incorporated all that he had learned in kinesiology dasses. He reflected on what he had learned in motor learning and
performance, biomechanics, and exercise physiology to come up with a basic practice plan. Brining his analytical ability to bear,
Mohammed recognized that the shot put is a closed skill (see chapter 3) that requires improvement in both physical performance
capacity (strength, mainly) and skill developments (specifically, a coordinated series of perfectly executed movements). He reviewed
his notes from his classes and believed that he now had a good handle on the mechanics of the event and understood the best way
to develop athletes' strength. The question of how to arrange practices, however, remained unanswered.
Please answer the following questions:
How would you design practice for this event? Would you vary the practice conditions by changing the distance and direction of the
athletes' throws? Would you have the athletes perform the movements without the shot during early trials? Would you have the
athletes perform the movements without the shot during early trials? Would you have them practice the skill repetitively- say, at least
25 successive trials in each practice session?

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
