the half-life of carbon-14 is 5,730 years. After 11,460 year, how much of original carbon-14 remains?
Inessa [10]

Via the half-life equation:

A_{final}=A_{initial}(\frac{1}{2})^{\frac{t}{h}}

Where the time elapse is 11,460 year and the half-life is 5,730 years.

A_{final}=A_{initial}(\frac{1}{2})^\frac{11460}{5730} \\\\A_{final}=A_{initial}\frac{1}{4} \\\\A_{final}=\frac{1}{4}A_{initial}

Therefore after 11,460 years the amount of carbon-14 is one fourth (1/4) of the original amount.

RSB [31]

Answer:

1.2 kg

Explanation:

Let UP ramp be the positive direction

                                                  F = ma

   T     -   Wt ||      -         Ff            = m(0)

  mg   -  Μgsinθ -      μΜgcosθ    = 0

m(9.8) - 13sin35 - 0.36(13)cos35 = 0        

                                                 m = 13(sin35 + 0.36cos35) / 9.8

                                                 m = 1.15205... ≈ 1.2 kg

Discuss the pros and cons of fission and fusion reactions.
Jet001 [13]

<u>Fission</u>: -

<u>Pros</u>:

- "It does not contribute to the air pollutants in the environment."

- "It does not need costly energy fuels."

- "It is capable of providing energy for 2 to 3 years."

- "It does not make global warming worse."

- "It produces a nuclear reaction that is important."

- "It helps with the field of astronomy."

<u>Cons</u>:

- "It can harm the environment in a way that it disposes waste."

- "It poses a risk to public health."

- "It can cause deadly and costly accidents."

- "It has the potential to open the door for terrorists to create powerful weapons."

<u>Fusion Reactions</u>: -

<u>Pros</u>:

- "Clean energy ."

- "Virtually limitless fuel available ."

- "No chain reaction. Easier to control or stop than fission ."

- "Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei) ."

- "Little or no nuclear waste. Core remains radioactive for only 100 years. Possibly radioactive structural elements ."

- "Very low fuel cost."

<u>Cons</u>:

- "Unproven (it will take another years of research to explore it on commercial scale) ."

- "Commercial power plants will be very expensive to build ."

- "Requires extremely high temperatures .

If cold fusion could be achieved, it would be much easier to implement."
