The value of a dependent variable changes in response to other changes in a scientific experiment.

Answer: Option C

Explanation:

In the course of going through a scientific experiment, we encounter two types of variables in the calculations,

An independent variable
The dependent variable

An independent variable doesn’t change in terms of values throughout the experiment and remains constant respective to all the changes whereas dependent variables are affected by the changes in the values of other variables or the modes of experiment.

The independent variable is termed as the presumed cause and the dependent variable is termed as the presumed effect. The subject of experiment is to find out the exact or relevant values of the dependent variables that can be a person, place, thing or a phenomenon.

An astronaut is in equilibrium when he is positioned 140 km from the center of asteroid X and 581 km from the center of asteroid

mariarad [96]

Answer:

0.05806

Explanation:

$m_x$ = Mass of asteroid x

$m_y$ = Mass of asteroid y

$r_x$ = Distance from asteroid x = 140 km

$r_y$ = Distance from asteroid y = 581 km

m = Mass of asteroid

Force of gravity between asteroid x and the astronaut

$F_1=\frac{Gm_xm}{r_x^2}\\\Rightarrow F_1=\frac{Gm_xm}{140^2}$

Force of gravity between asteroid x and the astronaut

$F_2=\frac{Gm_ym}{r_y^2}\\\Rightarrow F_2=\frac{Gm_ym}{581^2}$

Here these two forces are equal as they are in equilibrium

$\frac{Gm_xm}{140^2}=\frac{Gm_ym}{581^2}\\\Rightarrow \frac{m_x}{140^2}=\frac{m_y}{581^2}\\\Rightarrow \frac{m_x}{m_y}=\frac{140^2}{581^2}\\\Rightarrow \frac{m_x}{m_y}=0.05806$

The ratio of the masses of the asteroid is 0.05806
