Which of these would you include in a free body diagram of a coin sitting on a table? question 2 options: a)the forces of the coin pushing down on the table b)the force of gravity (weight) acting on the coin c)the room, to depict the physical setting d)the table

You should include the a)the forces of the coin pushing down on the table

B)the force of gravity (weight) acting on the coin

Explanation:

The free-body diagram of an object includes all the forces acting on the object itself, while does NOT include forces acting on other objects.

Therefore, the free-body diagram of the coin sitting on the table should include ONLY the forces acting on the coin.

Let's now analyze each option:

A)the forces of the coin pushing down on the table  --> NO. In fact, this force is exerted on the table, not on the coin, so this force should not be included in the free-body diagram of the coin.

B)the force of gravity (weight) acting on the coin  --> YES. This force is acting on the coin, so it should be included.

C)the room, to depict the physical setting   --> NO. The room is not a force, so it should not be included.

D)the table  --> NO. The table is not a force, so it should not be included.

Therefore, the only correct option is B.

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.
