Which lever decreases the force on a load and increases the distance it moves?
A third class lever has the effort in the middle, with the resistance located at one end, and the fulcrum located at the opposite end. This type of lever is designed to increase the distance the load moves while decreasing the force required to move it.
What is the relationship between distance ratio and mechanical advantage?
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
What class lever increases the distance of the force?
A class 2 lever increases the distance of the force because the effort arm is longer than the resistance arm. This type of lever allows for more force to be applied over a greater distance, making it easier to move a load.
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
In a first class lever, as the distance from the fulcrum to the point where the input force is applied increases, the mechanical advantage also increases. This means that the lever becomes more efficient at moving a load with less effort.
Which tyoe of lever always increases mechanical advantage?
A first-class lever always increases mechanical advantage, as the effort arm is longer than the load arm. The mechanical advantage is determined by the ratio of the lengths of the two arms of the lever.
Why is it are more families in the lower class?
Families in the lower class often face barriers such as limited access to education, lower levels of income, and lack of economic opportunities, which can contribute to their continued presence in the lower class. Systemic issues such as inequality, discrimination, and limited social mobility also play a role in perpetuating this cycle.
Why the median changes by changing the size of class intervals in frequency ditribution?
Because median is the mid of the class intervals. Therefore, it is a positional measurement. Hence, if the size of class interval increases or decreases then the middle position will also increase or decrease and thus median.
List three changes in the atmosphere as altitude increases from sea level upward?
As altitude increases, air pressure decreases due to lower density of air molecules at higher altitudes. The temperature typically decreases with altitude as the atmosphere becomes thinner and can't retain heat as effectively. Humidity levels may fluctuate, but generally moisture content decreases with altitude, leading to drier conditions.
Movement of individuals and groups within the social class structure is know as?
Upward or Downward Mobility
What is the trend found in Period 3 on the Periodic Table as the elements increase in atomic number?
1-Atomic size = decreases 2-Ioniztion energy = increases 3-Electronegativity = increases (except Argon) 4-Metallic character = decreases 5-Melting point = first increases then decreases
Does the wavelength increase as the frequency of an energy wave increase?
No. the wave length decreases as the frequency of an energy wave increases and vise versa. We acyually are learning thatin my 8th grade science class.
What is the social problem that Swift is proposing to solve?
Social class inequality
What are the three key types of inequality in America?
Race, gender, and class.
Examples of social mobility?
There are many examples of social mobility. A good example is President Obama who moved from a middle-class child to being a president. This is a form of vertical social mobility.
What structural factors can affect social mobility?
Structural factors that can affect social mobility include economic inequality, access to quality education, health care, and employment opportunities, as well as discrimination based on gender, race, ethnicity, and social class. Additionally, geographic location and family background can also play a role in determining an individual's ability to move up the social ladder.
What is the basic difference between an open class system and a closed class system?
The existence or nonexistence of social mobility
What is the basic difference between an open class system and a close class system?
The existence or nonexistence of social mobility
