An aluminium sphere with a mass of 4.2 kg and an initial temperature of 250°C is placed in a closed, thermally Isolated container with 30 kg water water - 4 185kg 1.c '). Determine the final/equilibrium temperature if the initial temperature of the water is 14 C.
A. 20.9°C
B. 132.0°C
C. 6.7°C
D. 26.3°C

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.
