Wahadło matematyczne wykonuje 10 pełnych wahnięć w ciągu 20 sekund. Oblicz częstotliwość wahań tego wahadła. Jaką drogę pokona kulka tego wahadła w tym czasie, jeśli wiadomo, że amplituda jego drgań wynosi 3 cm?

Explanation:

come closer and become far apart and become steam/gas

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.
