Iknow i need to find the area under the curve, but i think the sign is messing me up, , this is due in a few hours

no, they would

i'm a mechanic so i know all about this stuff.

none of the three examples you gave would do very good in a ice

motor oil gets extremely hot during operation and undergoes being thrown around, getting dirty,

syrups are sticky and thick. oil needs to be atleast a little runny to work in a car engine so that it does not clog parts like the camshaft or valves.

hope this !

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
