In 1601 the German astronomer Johannes Kepler became director of the Prague Observatory. Kepler had been helping Tycho Brahe in collecting 13 years of observations on the relative motion of the planet Mars. By 1609 Kepler had formulated his first two laws: i. Each planet moves on an ellipse with the sun at one focus. ii. For each planet, the line from the sun to the planet sweeps out equal areas in equal times. Kepler spent many years verifying these laws and formulating a third law, which relates the planets' orbital periods and mean distances from the sun. a. Plot the period time T versus the mean distance r using the following updated observational data.
Answers
Kepler discovered that Mars' orbit was an ellipse using the precise data that Tycho had gathered. He described his findings in Astronomia Nova, which is now known as Kepler's first two laws of planetary motion, in 1609.
German mathematician and astronomer Johannes Kepler made the discovery that the Earth and planets have elliptical orbits around the sun. He listed the three guiding principles of planetary motion. He made significant contributions to geometry and optics as well. The orbits of planets have an elliptical form. Equal areas are covered at equal times by a line connecting a planet and the Sun. The radius of a planet's orbit affects how long it takes for it to orbit the Sun. By studying more than 500,000 stars throughout its 9.6 years in orbit, Kepler found more than 2,600 planets. Prior to the likes of Copernicus, Kepler, and Galileo, no one was really sure what those big bright things in the sky even were, and everyone believed the planets revolved around Earth.

Research about Heritage
Answers
Answer:
Heritage is a version of the past received through objects and display, representations and engagements, spectacular locations and events.
Explanation:
Heritage is the full range of our inherited traditions, monuments, objects, and culture. Most important, it is the range of contemporary activities, meanings, and behaviors that we draw from them.
Heritage includes, but is much more than preserving, excavating, displaying, or restoring a collection of old things. It is both tangible and intangible, in the sense that ideas and memories--of songs, recipes, language, dances, and many other elements of who we are and how we identify ourselves--are as important as historical buildings and archaeological sites.
Heritage is, or should be, the subject of active public reflection, debate, and discussion. What is worth saving? What can we, or should we, forget? What memories can we enjoy, regret, or learn from? Who owns "The Past" and who is entitled to speak for past generations? Active public discussion about material and intangible heritage--of individuals, groups, communities, and nations--is a valuable facet of public life in our multicultural world.
Heritage is a contemporary activity with far-reaching effects. It can be an element of far-sighted urban and regional planning. It can be the platform for political recognition, a medium for intercultural dialogue, a means of ethical reflection, and the potential basis for local economic development. It is simultaneously local and particular, global and shared.
Heritage is an essential part of the present we live in--and of the future we will build.

the trade among nations has increased dramatically in recent years, and it is estimated that by 2015 the trade nations will exceed the trade nations.
Answers
International trade has increased dramatically in recent years, and it is estimated that by 2015 the trade across nations will exceed the trade within nations.
International trade occurs as a result of differences between countries natural resources availability as well as manufacturing production capacity. For example we know that China is highly specialized in manufacturing production and are able to manufacture products at a very competitive pricing with a huge production output, hence many countries would want to do international trade with China in order to obtain a more competitive pricing.
We can learn from the Ukraine - Russia conflict that global crisis has a negative impact on international trade. Russia being a major player in world oil production, and Ukraine being a major player in the global agricultural production such as grain; with competitive pricing for those resources; a disruption in the supply of Russian oil and Ukrainian grain cause a huge shortage and surge in the global price for those two commodities. In conclusion, international trade allows for a competitive pricing and access to more affordable foreign products which may otherwise be unavailable domestically.

17. Describe one cause of the urbanization of Texas that occurred during or after World War II
Use examples to support your answer.
Answers
The urbanisation of Texas during or after World War II The development of metropolitan centres was attracted to by the war-related industry, which also attracted farmers and residents of small towns.
Farmers, residents of small towns, and others were drawn into growing urban areas by the war-related business. Many of the workers were women and non-Caucasian. With a net population increase of 33 percent, Texas quickly shifted from being predominantly rural to becoming more urban. The Great Depression was quickly forgotten.
Texas's urbanisation is mostly a product of European immigration and culture. The Indian contribution is little because there isn't much that can be linked to Indian roots in contemporary Texas cities, with the possible exception of some demographic segments' genetic makeup.
