In ‘static equilibrium' the force pushing out against the inward pull of gravity is
Gemiola [76]
If you are referring to stars, the answer would then be pressure from the nuclear reactions 

The thermal pressure that pushes outward and against the pull of gravity in a star is caused by the nuclear reactions that is happening within the stars core. A lot of energy is released during these reactions which produce thermal pressure. The pressure then pushes outward.

plants and animals risk habitat loss as they have had exposure to dangerous byproducts of technology.
if someone creates something dangerous, then humans can inhale harmful chemicals in air pollution and it also consumes resources that are non-renewable
positives:
you can use technology to help the environment, through the use of recycling, purification of water and air to prevent pollution and contamination. for the second one you could say that technology has stopped the habitats from dying

It was found that ice cream sales decrease significantly as the temperature outside decreases; a very strong relationship was fo
zlopas [31]

Answer:

Value closest to 1

Explanation:

It is described from the scenario above that ice cream sales decreases as the outside temperature increases, hence showing a strong relationship between both variables (icream sales and temperature). The correlation Coefficient is a metric used in regression modeling to depict the strength of relationship between two variables, (The dependent and independent variables). Correlation Coefficient ranges from (-1 to +1). With values close to 1 or - 1. Also the positive and negative signs are used to show the type of relationship between the variables. If an increase in variable A leads to a decrease in variable B, then we have negative correlation (-) ; while an increase or decrease in both variables depicts a positive correlation. The most likely correlation Coefficient for the study above will be a positive value which is close to 1 since the relationship is described as strong.
