Mitchell records the amount of time a toy car takes to travel down a ramp one time for each of four slope angles. his lab
partner, sarah, suggests that he run the same set of trials two more times.
what arguments should sarah use to support her suggestion? check all that apply.

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 : )

c.the charges if the proton and electron and gravity

f=ma newton

f=100x2.5=250n

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
