A star moving AWAY from the Earth has a spectrum that is..

Answers

Answer 1

Answer:

Shifted towards red.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.

Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.

Hence, a star moving away from the earth has a spectrum that is shifted toward red. Thus, this shift is generally referred to as a red shift and it occurs due to the fact that the wavelength of light is longer and as such increases towards red (emitting a colour wavelength of red).

What the difference between ‘Oil sands’ and ‘tar sands’?

Answers

Answer: Hi there,

Tar Sands: Used more commonly than oil sands. It helps workers make manmade roads. This was introduced around the 1800s. Although it is quite similar to Oil Sands. The U.S uses this method to create roads instead of oil sands. They are mixed the same way as oil sands but these can produce gasoline.

Oil Sands: Seems more accurate than tar, they are mixed with water, clay, and sand. It forms bitumen which is created by the following items I mentioned which make the oil sands very dense because of what else they put in there (petroleum). It is very thick compared to tar sands. They are most important in the Candian economy.

What are some examples of the cooperation and the conflict that have shaped Eastern Europe?

Answers

Answer:

Britain’s referendum on the EU marks another step in the country’s long and troubled history with its European neighbours. Divorce or not, Europe will continue to have a huge influence over British politics and society – history has a few lessons for us here.

Europe made the UK. The emergence first of England as a nation state was the product of European pressures – to defend itself against Viking raids. So was the formation of the United Kingdom, which rallied England and Scotland against the France of Louis XIV.

Moreover, Europe has almost always been more important to us than the rest of the world. The 18th century statesman and philosopher Edmund Burke, for example, spoke of a “Commonwealth of Europe”, long before the British Commonwealth of Nations was even thought of.

The nature of the European challenge varied greatly over time. It was always strategic. In the Middle Ages the main enemy was France. In the 16th century and early 17th centuries it was Spain. From the late 17th to the early 19th century it was France again; in the mid to late 19th century it was Tsarist Russia. Then, in the early and mid-20th century it was first the Kaiser and then Hitler’s Germany; and then Russia again – with a brief interruption after the fall of the Berlin Wall – from the end of World War II to the present day.

haven't been here on Earth for a while,you know that every year is made up of four seasons.What causes the changes in seasons?
A-The rotation of the sun
B-The tilt of the Earth on its axis
C-The heating cooling of the sun
D-The rotation of the Earth on its axis

Answers

Answer: The Short Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Caves are erosional features, although depositional features form within them. Flowing and dripping water leave behind calcium carbonate, which is the precipitate of limestone dissolution. This precipitate in turn creates a form of limestone called travertine that is often white or cream-colored.

3. If the length of a diagonal of a cube is 12√3 cm, find its surface area and volume​

Answers

Diagonal = s root 3 where s= side
Therefore side = 12cm
Surface Area = 6s^2 = 6(12)^2 = 6(144) = 864 cm^2
Volume = s^3 = 12^3 = 1728 cm^3

Answer:

Diagonal=s root 3 where s=side

therefore side=12 cm

surface area=6s²

=6(12)²

=6(144)

=864 cm²

Is nuclear power likely to increase in the future and if so why? (answer clearly please)

Answers

The use of nuclear power will likely increase in the future as we move away from the use of fossil fuels. We are trying to use more sustainable energy like solar, wind etc but nuclear power provides a lot of more energy than these sustainable methods. However, the waste is extremely toxic towards the environment and the work is extremely dangerous. while it will be used more in the future, solar and wind power will most likely become commonly used sources for power.

Why do areas near the tropics like the Gulf of Mexico and the Caribbean sea receive lots of hurricanes each year?

Answers

Answer:

Hurricanes form both in the Atlantic basin, to the east of the continental U.S., and in the Northeast Pacific basin, to the west of the U.S. The hurricanes in the Northeast Pacific almost never hit the U.S., however, whereas the ones in the Atlantic basin strike the U.S. mainland just less than twice a year on average.

There are two main reasons for this disparity. The first is that hurricanes in the northern hemisphere form at tropical and subtropical latitudes and then tend to move toward the west-northwest. In the Atlantic, such a motion often brings the hurricane into the vicinity of the East Coast of the U.S. In the Northeast Pacific, the same west-northwest track carries hurricanes farther offshore, well away from the U.S. West Coast.

To determine a change of elevation on a topographic map what type of math would you use?

-subtraction
-addition
-division

Answers

Answer:

-subtraction

Explanation:

Elevation is the altitude of a place above a reference frame.

To find the difference between the elevation between two or places on a map, we perform a subtraction operation.

The differences in elevation is the subtraction of the two elevation values from one another.

For example if point A on a map is at 60m above sea level and point B is at 100m, the change in elevation is;

Change in elevation  = Elevation of B - Elevation of A = 100m  - 60m  = 40m

How does the size and shape of a rock influence its likelihood of being weathered? What is the general rule about surface are that can be applied to weathering?

Answers

Answer:

The chemical and physical properties of the rock influences the rate of weathering. This lead to change in its firm and size.

Explanation:

The weather and erosion both gave a dramatic impact on the composition of the earth's atmosphere. The impacts of chemical weathering reduce the impacts of carbon dioxide from the air. Running water contributes to erosion and weathering by loosing and removing the particles by abrading the rocks through the freezing and thawing.
