Marissa makes dye for fabrics by dissolving dye powder into water. She would like to find a way to more quickly dissolve the powder. She designs an experiment to see whether the particle size of the dye powder affects how quickly it dissolves. Marissa first gets a sample of blue dye powder with a large particle size. She grinds some of this powder to make samples with small and medium particle sizes. She fills three separate cups with 8 ounces of hot water. She then performs three trials. In each, she adds 20 grams of one of the dye samples to one of the cups. She stirs the mixture at a constant rate until she can no longer see the dye powder and the color is evenly distributed in the water. At this point, she records the time it has taken for the dye powder to dissolve. In each trial, why does Marissa add the same mass of dye powder to each cup?
ok so the answer should be 34 because of the quadratic formula of mathematics

how are wages determined in the labour market
Answer:
In a competitive labor market, the equilibrium wage and employment level are determined where the market demand for labor equals the market supply of labor. Like all equilibrium prices, the market wage rate is determined through the interaction of supply and demand in the labor market.
Explanation:
The point where the labor supply and demand curves converge to form an equilibrium is where the wage rate is set.
What do you mean by the labour market?The space where workers and employers interact is called a labour market. In the labour market, employees fight for the most fulfilling jobs and companies seek to hire the best candidates.
An economy's labour market runs on supply and demand for labour. In this market, the supply of labour is provided by the workers, while the demand for labour is represented by the enterprise. Changes in bargaining power have an impact on the supply and demand of labour in the market.
Because employees are a crucial component of the production process, employers want labour. To convert inputs into output, employees use tools and equipment. Employers couldn't manufacture goods and services and make money without people.
Therefore, the point where the labor supply and demand curves converge to form an equilibrium is where the wage rate is set.

How does federal system help in development of a country? Write

development goals on
Answer:
Federalism provides a way for different groups of people in different parts of the country to live together
Federal systems have at least two levels of government, the central level and a second level that includes territorial entities into which the country is divided, e.g. regions, states, provinces.
Federalism provides ways by which these different groups share power over common interests, but it also provides for these groups to have a level of autonomy vis-à-vis central state institutions
Federations are protected by a constitution regarding ways in which power is shared in central state institutions, but also regarding the powers and responsibilities of both the central state and provinces, states or regions.
But federalism is not a panacea. There are specific challenges that federalism alone cannot resolve, e.g. how to protect minorities, or the fact that federalism can be expensive as you need to build institutions not only and the central, but also at the region, state, provincial level. Sometimes the different levels have difficulties coordinating policies or policy responses, such as to pandemics or natural disasters.

Provide a rationale for why no one came to the aid of Kitty Genovese before she was murdered.
Answer: The bystander effect is a claim that people are less likely to help if there is a large group of people around.
Kitty Genovese was murdered by Winston Moseley on the thirteenth of March 1964. She cried out for help when she was being attacked nobody directly helped her. The reason for this was people thinking that someone else will help her.
Explanation:
Some witnesses claim that they did not understand what was happening and thought this murder to be a lover's quarrel. Thus, they did not perceive it as an emergency and did not respond with helping behavior.
What do you mean by rationale?Rationale refers to the reasons or a logical basis for any belief or action.

Primary succession would occur after a wildfire, tornado or flood
True or false
Answer:
FALSE
Primary succession occurs after volcanic eruptions and glacier movements.
Explanation:
When a biological community develops an ecological structure, we have what we call an ecological succession. A primary succession is basically the growth or development of plant and animal life in areas that were devoid of such life before, that is, areas that were barren. This process takes a long period of time, and the simple, initial biological communities in those areas are a result of the interaction of pioneer species - the first ones to arrive to the place. With time, the communities will become more complex. Finally, primary successions occurs in areas where lava has flown or where glaciers have retreated.
