A company that makes playground equipment is designing a new swing. The swing will sit in an open schoolyard that is unprotected from the Sun.
The company wants to use a thermal insulator to make the swing. This is so that the swing will not get so hot from the Sun that it
burns the children when they touch it.
Which of the following materials are thermal insulators the company could use to make the swing?
1. wood
II. stainless steel
III. plastic
IV. rubber
OA. I, III, and IV only
ОВ. I and II only
OC. I, II, and Ill only
OD
II and IV only

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

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.
