Students in a science class want to design an investigation to determine if fertilizer added to soil affects the average height of a plant over time. Which items would the students need to complete this investigation?
A tape measure, graph paper, a plant, and soil samples with the same amount of fertilizer
A microscope, a beaker, a plant, and soil samples with the same amount of fertilizer
A computer, a stopwatch, a plant, and soil samples with different amounts of fertilizer
A ruler, a calculator, a plant, and soil samples with different amounts of fertilizer

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
