In the equilibrium experiment, the meter stick is balanced at exactly 50.0 cm mark. You attach a mass of 600 g at 10 cm position and a mass of 300 g at 60 cm position. How much mass should you attach at 80 cm position to balance the meter stick

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

i need the answer to this too but idk it ; -;

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
