Answer:
The gravitational torque between the Moon and the tidal bulge of Earth causes the Moon to be constantly promoted to a slightly higher orbit and Earth to be decelerated in its rotation. As in any physical process within an isolated system, total energy and angular momentum are conserved.
The half-life of carbon-14 is about 5700 years. If you left those 100 carbon-14 atoms to sit around for 5700 years, how many would you expect to decay during that time?
Answer:
50 atoms have decayed during that time
Explanation:
The radioactive decay is represented as
[tex]N = N_0 * \frac{1}{2}^X\\[/tex]
Where N is the amount of radioactive element after a certain time period
N0 is the amount of radioactive element during the initial time period
X is the half life of the radioactive element
Substituting the given values in above equation, we get:
[tex]N = 100 * \frac{1}{2}^1\\N = 50[/tex]atoms
So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.
Hence, atoms of carbon-14 that decay during 5700 years are 100-50 - 50
Refer to the passage.
"All the scientific resources of Germany have apparently been brought into play to produce a gas of so virulent and poisonous a nature that any human being brought into contact with it is first paralyzed and then meets with a lingering and agonizing death.”
Sir John French, commander in chief of the British Expeditionary Force (BEF), 1915
Which of the following novel aspects of World War I contributed to the action described in the passage?
The Allies’ ability to attack German forces with military aircraft
The capability of British tanks to repel machine-gun fire
The attempt to block supply shipments in the Atlantic by using submarines
The stalemate and high casualties caused by trench warfare on the western front
Answer:
The stalemate and high casualties caused by trench warfare on the western front
Explanation:
Find a real-life mention of a derivative.
- The source of your quotation: The name of the publication, the date it was published, and where you found it.
- Quote the sentence or sentences that mention the derivative. If necessary, you can paraphrase material from earlier in the article to give some context for your sentences. Note that the material need not mention the word "derivative" explicitly, but instead may just talk about "change."
- Identify the derivative, as you did in the previous assignment; include units, and define all your variables.
Note any other information you think is interesting about your find. For example, what's the target audience for the periodical, and would they be surprised to know that they were brushing up against calculus? Or, what conclusions did the authors draw with the help of this derivative? Or, why is this topic of particular interest to you?
Answer:
This page in a nutshell: Summarize in your own words instead of closely paraphrasing. Closely paraphrased material that infringes on the copyright of its source material should be rewritten or deleted to avoid infringement, and to ensure that it complies with Wikipedia policy. Public domain sources and CC-BY-SA-compatible sources may be closely paraphrased, and limited close paraphrasing of copyrighted sources may also be permitted as fair use. Attribution is always required.
For information on copy and pasting text, see Wikipedia:Copying text from other sources.
Close paraphrasing is the superficial modification of material from another source. Editors should generally summarize source material in their own words, adding inline citations as required by the sourcing policy.
Limited close paraphrasing is appropriate within reason, as is quoting, so long as the material is clearly attributed in the text – for example, by adding "John Smith wrote ...", together with a footnote containing the citation at the end of the clause, sentence or paragraph. Limited close paraphrasing is also appropriate if there are only a limited number of ways to say the same thing.
Close paraphrasing without in-text attribution may constitute plagiarism, and when extensive (with or without in-text attribution) may also violate Wikipedia's copyright policy, which forbids Wikipedia contributors from copying an excessive amount of material directly from other sources. Public domain material must likewise be attributed to avoid plagiarism. If the source material bears a free copyright license that is compatible with Wikipedia's licenses, copying or closely paraphrasing it is not a copyright violation so long as the source is attributed somewhere in the article, usually at the end.
The best way to prevent close paraphrasing is to understand clearly when it is a problem, how to avoid it, and how to address it when it appears.
