How did Area Rule impact everyday aviation?

1 answer:

6 0

The Area Rule, is a design technique used to reduce an aircraft's drag at transonic and supersonic speeds, particularly between Mach 0.75 and 1.2. It improved everday aviation by increasing overall speed and efficiency.

leonid [27]

Changes to the mutation is harmful
Mutations are basic inputs of a organism .
So playing with mutations is like inviting danger.
It will give beneficial and neutral defects to the organism and may take life of it

tigry1 [53]

Answer:

geologic unit

When reading a geologic map, rock units are labeled with letter codes. The first upper-case letter indicates age of the geologic unit, while the following lower case letters represent geologic unit's name or the type of rock of which it is comprised.

Explanation:

Geologist have divided the history of the earth into 4 main periods of time; the Eons, the Eras the Periods and the Epoch. On a geological map, an initial capital letter is usually followed by one or more lower case letters while the lower case letters indicate either the name of the unit, if it has one, or the type of rock, if the unit has no name.

PLEASE HELP What is the evidence of earth being made of matter that is constantly changing?

Alik [6]

HERE IS YOUR ANSWER BRO

I HOPE IT WILL HELP YOU.

This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution. (Credit: Luthi, D., et al.. 2008; Etheridge, D.M., et al. 2010; Vostok ice core data/J.R. Petit et al.; NOAA Mauna Loa CO2 record.) Find out more about ice cores (external site).

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Scientific evidence for warming of the climate system is unequivocal.

- Intergovernmental Panel on Climate Change

The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1

Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.3

## The evidence for rapid climate change is compelling:

Global Temperature Rise :-

The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.4 Most of the warming occurred in the past 35 years, with the six warmest years on record taking place since 2014. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months.

How did the “scramble for africa” change the culture of africa?

Hoochie [10]

Answer:

Explanation:

The many people swarming to Africa, could'nt have reduced diversity...It would have increased it. Elimination of communism? Nope...The head of the country wouldnt be influenced too much by the people coming in. European influence would'nt have been reduced all too much either. The only answer id D. It brought new ideas to the continent. The people coming to Africa would have had a whole din of ideas, just waiting to improve the average African life. So, yeah, they did improve it.
