The region's prime farmland soils and globally significant agricultural industry make it an important focus of our work. Active in the Midwest since the early 1980s, AFT: Works hand-in-hand with farmers to help them protect drinking water and reduce soil erosion by adopting conservation practices like cover crops.

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).
Answer:
C. 2π cm
Explanation:
Measure of the length of arc(QR) = θ/360 × 2πr
Where,
θ = 60°
r = 6 cm
Plug in the values
Measure of the length of arc(QR) = 60/360 × 2 × π × 6
= 1/6 × 12 × π
= 2 × π
= 2π cm
The answer is competition for natural resources will increase. More people means people will fight for limited natural resources. It’s the only one that seems logical. Oxygen will not increase since humans do not produce it, we cut down the trees and plants that do to build our houses. More land will not be available it will decrease as more people inhabit the planet and take up more space. People will use more fossil fuels because more people = companies take advantage to sell their product. They don’t care about the environment so if the demand goes up then they will supply more. Even though there’s a limited amount, therefore meaning that the overall amount will decrease.
