Answer:
![-22.7 m/s^2](https://tex.z-dn.net/?f=-22.7%20m%2Fs%5E2)
Explanation:
This is a uniformly accelerated motion, so we can determine the deceleration of the car by using a suvat equation:
![v^2-u^2=2as](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as)
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the car in this problem,
u = 27.8 m/s
v = 0
s = 17 m
Solving for a, we find the acceleration:
![a=\frac{v^2-u^2}{2s}=\frac{0-27.8^2}{2(17)}=-22.7 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv%5E2-u%5E2%7D%7B2s%7D%3D%5Cfrac%7B0-27.8%5E2%7D%7B2%2817%29%7D%3D-22.7%20m%2Fs%5E2)
Answer/Explanation:
Part 1: 13 chromosomes.
Reproductive cell, male or female, whose nucleus contains only one chromosome of each pair (they are said to be haploid n = 13) and which unites with the gamete of the opposite sex (fertilization) to give birth to an egg (zygote 2n = 26 ) diploid resulting from the association of the two gametes with each his half of the genetic capital.
2. The process of creating a new flower is called reproduction.
Human reproduction is the process by which a man and a woman engender a new individual. It is a method of sexual reproduction.
<u>Sexual reproduction requires:</u>
- Cells carrying parental genes, gametes: eggs and spermatozoa generated by meiosis.
- The encounter between male and female gametes: fertilization.

Explanation:
Momentum = mass × velocity
![300 = 20 \times v \\ velocity = 15 \: {ms}^{ - 1}](https://tex.z-dn.net/?f=300%20%3D%2020%20%5Ctimes%20v%20%5C%5C%20velocity%20%3D%2015%20%5C%3A%20%20%7Bms%7D%5E%7B%20-%201%7D%20)
For power:
![P = \frac{force \times distance}{time} \\ \\ P = force \times ( \frac{distance}{time} )](https://tex.z-dn.net/?f=P%20%3D%20%20%5Cfrac%7Bforce%20%5Ctimes%20distance%7D%7Btime%7D%20%20%5C%5C%20%20%5C%5C%20P%20%3D%20force%20%5Ctimes%20%28%20%5Cfrac%7Bdistance%7D%7Btime%7D%20%29)
but distance/time is velocity, so:
![P = force \times velocity](https://tex.z-dn.net/?f=P%20%3D%20force%20%5Ctimes%20velocity)
but force = mass × acceleration:
![P = (mass \times acceleration) \times velocity \\ P = (20 \times 10) \times 15 \\ P = 3000 \: \: watts](https://tex.z-dn.net/?f=P%20%3D%20%28mass%20%5Ctimes%20acceleration%29%20%5Ctimes%20velocity%20%5C%5C%20P%20%3D%20%2820%20%5Ctimes%2010%29%20%5Ctimes%2015%20%5C%5C%20P%20%3D%203000%20%5C%3A%20%20%5C%3A%20watts)
[ taken acceleration to be 10 m/s² ]
what about it do you need to know love?
-- Starting from nothing (New Moon), the moon's shape grows ('waxes')
for half of the cycle, until it's full, and then it shrinks ('wanes') for the next
half of the cycle.
-- The moon's complete cycle of phases runs 29.53 days . . . roughly
four weeks.
-- So, beginning from New Moon, it spends about two weeks waxing until
it's full, and then another two weeks waning until it's all gone again.
-- After a Full Moon, the moon is waning for the next two weeks. So it's
definitely <em>waning</em> at <em><u>one week</u></em> after Full.
