Answers

Answer 1

Simple machines simply make work easier by directing forces over distances.

What was Simple Machines Viewing ?

Instead of lifting a heavy box upstairs, you can hook it to some ropes and pulleys and pull it up. Or you can get a ramp and slide it upstairs. Either way, it’s less sweat to use the pulleys or the ramp than it is to lift the box straight up by yourself because the force you need is more spread out. Levers, ramps, screws, wheels, wedges, and pulleys are all simple machines designed to direct forces.

With simple machines we don’t have to push or pull as hard, but we have to push or pull over a longer distance. It’s easier to walk up a long set of stairs to the top of the Empire State Building than it would be to climb a ladder to the top, but the set of stairs would be much longer than the ladder.

Structural discrimination theories

Answers

Answer:

Cultural deficiency theories

Explanation:

Cultural deficiency refers to a theoretical argument that the cultural attributes or practices often associated with historically disenfranchised racial/ethnic groups (specifically, blacks and Latinos) have prevented them from assimilating and attaining social mobility within U.S. society

Examples of cultural deficiencies include limited outlooks and attitudes toward the future, a failure to internalize the work ethic, instant gratification behavior, a lack of parent involvement in schools, low intellectual abilities, an emphasis on masculinity and honor, and an aversion to honest work. Other so-called deficiencies, as identified by Stanley Eitzen and Maxine Baca Zinn (2006), may include early initiation to sex among children, female-headed households, a fatalistic attitude toward life, and a limited interest in education. The cultural deficiency argument also posits a causal linkage between certain cultural attributes and upward socioeconomic mobility. It identifies the attributes of economically and socially successful middle-class whites as the mechanisms that enable success (e.g., emphasis on achievement, education, and independence) vis-à-vis legal or institutional structures and social ideologies.
