Question 13 of 25 Two samples of water are mixed together. The first sample has a mass of 1.0 kg and is at 0°C. The second sample has a mass of 0.50 kg and is at 100°C. What is the equilibrium temperature of the water, assuming this is a closed system? (Gwater = 4.18 kJ/kg:°C)​

whichever one it is, it's definitely not one that you included on the list you provided.

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.
