Answer:
<u>Life expectancy index, Education index, Literacy index, Income index all the countries are ranked based on these parameters</u>.
Explanation:
- As HDI is a statistical composite index and the formula for calculating the Human Development Index is (life expectancy x education index x income index).
- The higher the score the higher is the value of the development of the country. Developed by Dr. Mahbub Al Haq and Amartya sen.
- The HDI shows low human development scores from 0.0 to 0.5. The medium human development scores between 0.5 and 0.8. High human development for HDI scores ranges from 0.8 and 1.0.
- Though there are limiting factors of HDI as it does not take into account the qualitative factors and cultural identity into considerations, As others have suggested the HDI should be more human-centered ranging from gender to environmental biodiversity.

Abstract
Most planetary systems are formed within stellar clusters, and these environments can shape their properties. This paper considers scattering encounters between solar systems and passing cluster members, and calculates the corresponding interaction cross-sections. The target solar systems are generally assumed to have four giant planets, with a variety of starting states, including circular orbits with the semimajor axes of our planets, a more compact configuration, an ultracompact state with multiple mean motion resonances, and systems with massive planets. We then consider the effects of varying the cluster velocity dispersion, the relative importance of binaries versus single stars, different stellar host masses, and finite starting eccentricities of the planetary orbits. For each state of the initial system, we perform an ensemble of numerical scattering experiments and determine the cross-sections for eccentricity increase, inclination angle increase, planet ejection, and capture. This paper reports results from over 2 million individual scattering simulations. Using supporting analytic considerations, and fitting functions to the numerical results, we find a universal formula that gives the cross-sections as a function of stellar host mass, cluster velocity dispersion, starting planetary orbital radius, and final eccentricity. The resulting cross-sections can be used in a wide variety of applications. As one example, we revisit constraints on the birth aggregate of our Solar system due to dynamical scattering and find N ≲ 104 (consistent with previous estimates).
The four factors which reflected population density is:
Natality rate
Mortality rate
immigration
emigration
Answer:
True
Explanation:
Escape velocity is the speed needed for any freely moving object to run away from the gravitational pull of the massive body like the sun. This depends on the direction of movement as earth's escape velocity is 465m/s at the equator so a rocket would need a speed of 10.73 km from where the rocket would launch the surface velocity would impact it and the escape velocity would eventually decrease due to friction and gravity pull.
Answer:
Remnant low.
Explanation:
If only an L is displayed, then the system is forecast to be a remnant low. The letter inside the dot indicates the NHC's forecast intensity for that time:
D: Tropical Depression – wind speed less than 39 MPH
S: Tropical Storm – wind speed between 39 MPH and 73 MPH
H: Hurricane – wind speed between 74 MPH and 110 MPH
M: Major Hurricane – wind speed greater than 110 MPH
