In an experiment, an independent variable is the one that is controlled in order to measure the effects of the dependent variable. The dependent variable is the one that is being tested or measured.
In this example, the dependent variables would be the flashcards or the underlining, as those are the variables that are going to be measured. <em>The independent variable is the quality of the study.</em>
Answer:
F = 8.45 * 10^-8 N
Explanation:
The gravitational force is calculated using
F = GMm/r²
Where
G represent gravitational constant = 6.67 * 10^(-11)
M = Mass of the boy = 78kg
m = Mass of the girl = 65kg
r = Distance between them = 2m
Substitute these values in the formula, we have:
F = (6.67 * 10^(-11) * 78 * 65)/2²
F = (6.67 * 78 * 65 * 10^(-11))/4
F = (33816.9 * 10^(-11))/(4)
[Divide by the denominator]
F = 8454.225 *10^(-11)
[Expand]
F = 8.454225 * 10³ * 10^(-11)
F = 8.454225 * 10^(3-11)
F = 8.454225 * 10^-8
[Approximate]
F = 8.45 * 10^-8 N
Hence, the force of attraction between them is 8.45 * 10^-8 N
Answer:
The colonies did not abolish slavery after the Revolutinary War was because the United States economy depended on slave labor, and lawmakers did not want to dismantle the economy.
