paragraph-how high GDP can affect child mortality​

Answers

Answer:

The authors found that, on average, a 1% reduction in the per capita GDP implies a 0.24 to 0.40 increase in infant mortality per 1,000 live births. In a more recent study, O’Hare et al.17 found effects of 0.33 for infant mortality and 0.28 for under-five mortality. These results are higher than those observed in the present study, which found an association of approximately 0.12 for infant mortality and 0.10 for under-five mortality rate for the total sample, and 0.15 and 0.14, respectively, for the subsample of low- and middle-income countries. This difference is probably due to the countries included in the sample, as Baird et al.14 and O’Hare et al.17 include only middle- and low-income countries in their analysis, while the present study included countries from the three income strata, with only 14% of the sample consisting of low-income countries. According to Maruthappu et al.6, the effect of economic crises on the health of children under five in the poorest countries is three-fold higher than the effect on children in high-income countries.

Calculate the amount, in grams, of an original 300-gram sample of radioactive isotope Potassium-40 remaining after
3.9 billion years if its half life equals 1.3 x 10^9 years.

Answers

Answer:

The current amount of the Potassium-40 sample is approximately 37.521 grams.

Explanation:

The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time ([tex]m (t)[/tex]), in grams, is described below:

[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)

Where:

[tex]m_{o}[/tex] - Initial mass, in grams.

[tex]t[/tex] - Time, in years.

[tex]\tau[/tex] - Time constant, in years.

The time constant can be found from half life ([tex]t_{1/2}[/tex]), in years, described in statement:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)

If we know that [tex]m_{o} = 300\,g[/tex], [tex]t = 3.9\times 10^{9}\,yr[/tex] and [tex]t_{1/2} = 1.3\times 10^{9}\,yr[/tex], then the current amount of the sample is:

[tex]\tau = \frac{1.3\times 10^{9}\,yr}{\ln 2}[/tex]

[tex]\tau \approx 1.876\times 10^{9}\,yr[/tex]

[tex]m = (300\,g)\cdot e^{-\frac{3.9\times 10^{9}\,yr}{1.876\times 10^{9}\,yr} }[/tex]

[tex]m\approx 37.521\,g[/tex]

The current amount of the Potassium-40 sample is approximately 37.521 grams.

Can someone please write a summary based upon the Middle East and Russia?

Answers

Answer:

Since the 1930s the Middle East has emerged as the world's most important source of energy and the key to the stability of the global economy. This tumultuous region produces today 37% of the world's oil and 18% of its gas. When it comes to reserves, the Persian Gulf is king. --> MIDDLE EAST.

Russia, country that stretches over a vast expanse of eastern Europe and northern Asia. Once the preeminent republic of the Union of Soviet Socialist Republics (U.S.S.R.; commonly known as the Soviet Union), Russia became an independent country after the dissolution of the Soviet Union in December 1991. --> RUSSIA

Explanation:

SUMMARY UPDATED:

The middle east may be emerged as one of the most important source of energy to the world but Russia is one of the biggest places in the world although it is an independent country causing there to be more recourses from Russia compared to Middle East! The only difference here is that Middle East has been important since 1930s but Russia became independent form Soviet Union on 1991.

What did the extinction of the dinosaurs lead to

Answers

Answer:

A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs. Food chain imbalances lead to the starvation of the dinosaurs.

After the dinosaurs went extinct a bunch of new roles were open that used to be inhabited by dinosaurs. The extinction allowed for other animals to grow and evolve in ways they couldn’t when the dinosaurs existed. More specifically the extinction of the dinosaurs led to the rise of mammals in the Cenozoic.

A boy is flying a kite. His kite string is extended 50 meters long. The boy is 1.7 meters tall, and the angle of elevation of the kite to the boy's hands is 12°. How high is the kite flying above the ground?

Answers

Answer:

12.1 meters

Explanation:

Please check the attached image for a diagram of the question

We are given the value of the hypotenuse and we are to determine the value of the opposite side. Thus, we would use sin

Sin = opposite / hypotenuse

sin 12 = opposite / 50

0.2079 =  opposite / 50

opposite =  0.2079 x 50 = 10.4 meters

height of the kite above the ground = 10.4 + 1.7 = 12.1 meters
