T(1/2)=1/(k[NO2])
[NO2]=1/(kt(1/2))
[NO2]=1/(0.54M-1 s-1*22s) seconds cancel
[NO2]=1/11.88=0.0842
inital mole= 0.0842*volume(2.5)=0.210 mols
Answer:
9.1 mg/dL
Explanation:
A normal distribution is symmetrical, the area below the curve of negative Z-scores is equal to the area below the curve of positive Z-scores, Z measures the statistic observed and the parameter of the population.
And it is:
Z = (x - μ)/σ
where μ is the mean (9.5 mg/dL), x is the borderline, and σ is the standard deviation, which is 0.3 mg/dL.
The Z-score can be calculated in excel by the function =NORMSINV, and the factor will be the percente considered (10% = 0.1)
NORMSINV(0.1) = -1.28155
So,
-1.28155 = (x - 9.5)/0.3
x - 9.5 = -0.384465
x = 9.1 mg/dL
Answer:
The gravitational potential energy it had from being above the ground is converted to kinetic energy as the rock falls. As kinetic energy increases, the velocity of the rock will also increase. However, if one considers the air, the rock will lose energy as it falls due to air resistance. If the cliff is high enough, the acceleration due to gravity and the air resistance due to the velocity will be exactly equal and there will be no change in kinetic energy.

Hunting deer can be considered resource extraction. It involves the loss of biodiversity.
<h3>What does resource extraction mean?</h3>
Resource extraction refers to the usage of fundamental resources (biodiversity resources) from the environment.
Hunting deer is considered a resource extraction activity because this activity involves the loss of biodiversity.
Biodiversity is a fundamental issue for the health (homeostasis state) of the whole ecosystem.
