Answer:
Because wind is able to do work.
Explanation:
Work has different definition in physics and economic.
In physics, work refers to a transfer of energy to a certain object that is caused by the use of force in the direction of the displacement.
Let's take windmill as an example.
Windmill utilize the force of wind to generate electricity. This could only happen because wind could produce kinetic energy that is directed to rotate the generator within the windmill. This rotation of the generator is what produced the electricity. This process wouldn't be possible if wind does not have energy.
Pros: more equality, everyone can pay for things
Cons: Less mega rich people, don't need special skills, people may de lazy
Cross-sectional research involves the comparison of two or more pre-existing groups of people under the same criteria.
<h3>What is
Cross-sectional research?</h3>
A cross-sectional study is a form of observational study in medical research, social science, and biology that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data.
Cross-sectional studies are used to analyze a population's illness burden or health requirements, and they are especially effective in informing health resource planning and allocation. A cross-sectional survey can be used to measure the burden of a certain disease in a defined population.
Cross-sectional studies capture a single point in time, gathering data from a research group at a particular point. This is often done with a single survey, questionnaire, or observation.
