Enter your answer in the provided box. what is the value of ni for an electron that emits a photon of wavelength 95.04 nm when i
Sloan [31]
<span>Ni = 5 The Rydberg formula for hydrogen is 1/w = R(1/a^2 - 1/b^2) where w = wavelength in vacuum R = Rydberg constant 1.0973731568508x10^7 1/m a,b = integers greater than or equal to 1 and a < b Now we need to select the value for a. a = 1 will converge towards 91.13 nm a = 2 converges towards 364.51 nm a = 3 converges towards 820.14 nm ... Because of this, we will assume a = 1 for this problem since it converges closest to the wavelength given. Substitute known values 1/w = R(1/a^2 - 1/b^2) 1/9.504x10^-8 = 1.0973731568508x10^7(1/1^2 - 1/b^2) 10521885.52 = 1.0973731568508x10^7(1/1 - 1/b^2) 0.958824759 = 1 - 1/b^2 -0.041175241 = -1/b^2 0.041175241 = 1/b^2 24.28643927 = b^2 4.928127359 = b So Ni = 5.</span>

The body uses two types of amino acids: essential and nonessential. Which of the following statements about essential and noness
zlopas [31]

Answer:There are 11 nonessential amino acids.

Explanation:amino acids are monomers of proteins.proteins are made up of carbon,hydrogen, oxygen and nitrogen.there are 20 amino acids found in proteins.

Plants cam produce all the amino acids they need but animals cannot.

Essential amino acids are those that animals cannot produce by themselves and so need to obtain from their diet.there are 9 in numbers.

Non-essential amino acids are produced by the animals.they are not necessarily non-essential as the name indicates.they are 11 in numbers.

Which point in this graph shows the beginning of a period of exponential
IgorLugansk [536]

Answer:

C. Point B

Explanation:  

The exposed curve represents a logistic growth model. Population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.

Referring to population size as N, when

  • N<K, the population can still grow.
  • N approximates to K, the population´s growth speed decreases.
  • N=K the population reaches equilibrium,
  • N>K, the population must decrease in size because there are not enough resources to maintain that size.  

The sigmoid curve represents the logistic growth model.

  • Point A: During this period, the population size is relatively stable. Little growth is expressed.
  • Point B: At the beginning of this period, population growth increases softly. The more individuals are in the population, the more that reaches sexual maturity and get to reproduce, leaving fertile offspring. This fertile offspring also get to reproduce and leave more fertile individuals. At the end of the period, the curve shows a sharp slope, reflecting the significant increase in the population reproductive rate.  
  • Point C: At the beginning of this period, the population keeps on growing exponentially. But at the end of the period, the curve tends to stabilize, meaning that the population stops growing in size so fast. The population slow and gradually reaches the equilibrium point, K.
  • Point D: The population got to stabilize.
