Question 8 of 20 1 Point
Suppose you use three different scales to weigh a bag of oranges. One scale
says the bag weighs 2.1 lb, a second says it weighs 2.2 lb, and a third says it
weighs 2.1 lb. The actual weight of the bag of oranges is 2.153 lb. Which of
the following best describes these results?
A. Neither accurate nor precise

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

a and c

c is 100% but i am confused in a

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.
