Determine the net force on an object which weighs 400 N on earth and produces an acceleration of 2 m/s^2

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

Fitness is the ability to perform only very light levels of physical activity.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
