A projectile is able to orbit the Earth at what speed?

Answers

Answer 1

about 8000 m/s

It so happens that the vertical distance that a horizontally launched projectile would fall in its first second is approximately 5 meters (0.5*g*t2). For this reason, a projectile launched horizontally with a speed of about 8000 m/s will be capable of orbiting the earth in a circular path.

why does earth have a great physical variations. Mentioned any three causes.​

Answers

Explanation:

The processes used by these actions are known as Weathering and Erosion.

Rainfall (water from the cloud) falls carrying out two major actions, firstly, it dissolves chemicals in the atmosphere and this solution causes chemical reactions on the various surfaces it falls on thereby weakening those surfaces through this action and secondly, by its impact on it wears off the surface. This second action becomes more vivid when you study the impact of a drop of water on a sandy surface. The impact dislodges the soils particles from others.

When there is significant amount of rainfall it leads to runoff (water running on the surface) and this runoff has enough force to move loose soil and rick particles to be deposited at a new location. The movement of these particles causes wear and tear on the surface on which they are moved and over time a new landscape evolves.

Water in the form of ice also causes significant landform changes especially in the temperate regions. This occurs through a process called ice or frost wedging. This essentially means water lodging in cracks and crags of rock get frozen and since frozen water expands it forces the crack to become wider and often times dislodging part of the rock surface.

Identify and briefly describe the major factors which create
four separate and distinct seasons for the people of Indiana .

Answers

Answer:

tilting of the earth.

Explanation:

Tilting of the earth is the factor which is responsible for seasons. Those areas which receives direct sunlight have hot climate such as areas at and near equator, while those areas which are nearer to the poles have cold climate. During spinning of earth, it tilted which causes seasons. There are certain planets which has no tilting so there is no season on that planet while our earth tilted about 23.5 degree which is the main cause of 4 seasons in different countries like Indiana.

Explanation:

Suppose Earth’s axis was perpendicular to the plane of Earth’s orbit around the Sun. How would the climate at the place you live differ from the climate today? How would it change if Earth’s orbit became much more elliptical?

Answers

Answer:

the earth is tilted 28 degree

Explanation:

The main reason why we have seasons during the year is because the Earth is tilted 23.5 degrees on its axis. In it's orbit around the sun, when the Earth is tilted toward the sun it is summer in the Northern Hemisphere and when the Earth is tilted away from the sun it is winter in the Northern Hemisphere. In the Southern Hemisphere it would be the other way round. Since the Earth orbits the sun steadily, this pattern repeats itself every year.

Well, if the Earth was not tilted, the plane of the Earth's poles would always be perpendicular to the sun, and. The sun would always be just on the horizon 24 hours a day on every day at the poles. There will be no nights at all in the polar regions. Every day would be an "equinox" and throughout the Earth (except the polar regions) there will be a 12 hour "day" and a 12 hour "night" and the sun angle would be about the same every day. There would no longer be seasons as we know them now. The climate, i.e., temperature and the rainfall pattern would not vary much. It would always be hot in the equatorial region and cold at the polar egions. The same climate will last throughout the year, and year after year.

The changes in the oceans and atmosphere would result in tremendous and unpredictable changes in conditions on the earth's surface including shifts in the oceans' levels and changes in the location and extent tropical areas. The tropic of Cancer and tropic of Capricorn would be meaningless because there would be no more "solstices" - it would be an eternal "equinox" meaning the sun rises exactly due East, and sets exactly due West after passing over the equator, day after day, year after year.

There will be a profound effect on the migratory birds and animals. They will find no reason for migration as there are no more seasons. Imagine what may happen if all the bird migration stops! Presently, because of migration, the population of millions of migratory/non migratory creatures are in balance; but if there were no migration, their populations may increase uncontrollably, causing a major zoological imbalance. (Imagine what will happen in East Africa. Every year, blue wildebeest have a long-distance migration looking for greener pastures, coinciding with the annual pattern of rainfall and grass growth. With no seasons there would be no need to migrate.)

And then, an Earth without it's tilt would be divided into climate "bands" that would get progressively colder as we moved away from the equator in both directions. People may not be able to survive the continuous winter of the higher latitudes - like Scandinavia, Greenland, Siberia, Mongolia etc. - and so the population of the Earth would probably concentrate in the midsection tropical/equatorial regions of the planet. Needless to mention, there would be chaos! We may not be able to feed ourselves anymore, because:

The tropical zone would be humid and so, continuous rainfall would quickly erode the soil and drain away the top-soil and the nutrients, making the land useless for agriculture.

We would be plagued by diseases, the pathogens of which thrive in warm, humid environments. You must be aware that cold climate protects much of the world's population from disease carrying tropical insects which account for diseases not only in humans, but also crops and livestock. The tropics is home to MALARIA, EBOLA, and HIV. We just cannot imagine the devastation caused by deaths due to diseases coupled with hunger. As I write this, the world population is 7.32 billion and the annual increase is estimated at 1.10%. Imagine the lot living within some 40° north and south of the equator!

Let's not forget, as our numbers increase, the numbers of other inhabitants of the planet has steadily decreased; many species have even gone extinct due to loss of habitat, pollution, and global warming. With the human population concentrated in the tropical regions, there is bound to be overfishing and over-hunting. Scientists believe that with the current rate of extinction, we will experience a mass extinction in which 75 percent of the planet's species will be extinct within short period of time, like 300 years or so. On an Earth without it's tilt, it would be a lot sooner.

So whatsay, we let the present tilt of the Earth continue until further notice?

How does meteorites  tells the age of solar system?

The first solid substance to develop in our solar system can be found in some so-called "primitive" meteorites. The age of this substance, 4.568 billion years, has been used to calculate the age of our solar system. Many ancient meteorites have practically not altered since they were created.

More than 4.5 billion years ago, when the solar system was still young, dust and other microscopic particles that eventually combined to create asteroids gave rise to chondrites. Chondrites are essential to the investigation of the solar system's origin, age, & composition because they developed at the same time as the solar system.

Answer:

A : 3.5 billion years ago

Approximately about 3.5 billion years ago the fossil record extend.  The reason the correct option is a.  

According to radiometric dating, Earth formed around 4.5 billion years ago. The oldest fossils, which are found in rocks older than 3.5 billion years (see Precambrian epoch), resemble creatures like bacteria and cyanobacteria (blue-green algae). The so-called Ediacara fauna, which consists of small, soft-bodied wormlike organisms, is where the oldest animal fossils, dating back roughly 700 million years, may be found. In rocks that are around 540 million years old, there are many fossils with mineralized skeletons that belong to several living phyla.

The oldest fossils date back between 3.48 and 4.1 billion years. A geological timescale and the relative ages of various fossils were recognised in the 19th century as a result of the discovery that specific fossils were linked to specific rock strata.
