Nuclei with a higher than desired neutron-to-proton ratios tend to undergo which type of decay?

1 answer:

8 0

Hey there!

Nuclei with a high neutron-to-proton ratio usually undergo a beta emission.

Beta emissions, unlike some other types, is radioactive decay throughout these particles, and can have half lives like other types of exponential (usually) decay. Neutrino, along with <em>beta rays,</em> are coming from, or emitted from the nucleus - hence the name.

Hope this helps!

Joyce is planting tulips in her garden, and she has 5 red bulbs and 5 white bulbs to plant in one row. What is the probability t

Stolb23 [73]

Answer:

$\frac{1}{126}$ or 0.0079.

Explanation:

Joyce is planting tulips in her garden.

Number of red (R) bulbs = 5

Number of white (W) bulbs = 5

Total number of ways to plant 10 bulbs in one row is

$\text{Total ways}=\frac{10!}{5!5!}$

$\text{Total ways}=\frac{10\times 9\times 8\times 7\times 6\times 5!}{5\times 4\times 3\times 2\times 1\times 5!}$

Cancel out common factors.

$\text{Total ways}=252$

It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.

Required outcomes are

RRRRRWWWWW and WWWWWRRRRR

$\text{Required outcomes}=2$

Formula for probability:

$Probability=\frac{\text{Required outcomes}}{\text{Total ways}}$

$Probability=\frac{2}{252}$

$Probability=\frac{1}{126}$

$Probability\approx 0.0079$

Therefore the required probability is $\frac{1}{126}$ or 0.0079.

Licemer1 [7]

When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.
