No, only this one. Have you managed to solve it?

Because it applies some force on the area, isn't it? It's so easy, that I just need to divide 60N by 0,2M?

Hello. I tried to solve this question: So F1D1=F2D2. Thus: 60N/ 0,06m x 0,2 m= f/0,02m x 0,04m =100 Newton applied to the piston, but this doesn't fit to the answers offered. What did I wrong?:(

for those who concerned I solved the second one: it's= 1000 x 1.5 = 100 x 4.5 + 1.5x x=700N I hope somebody will help me with the first one:)

Hello. I am preparing for certain exams and I encountered these question. Can you guys help me to solve these ones? The 1st one I tried to apply formula about density (p=m/v), but I guess that I need to solve through that ice cube. That I firstly sort out the number of atoms in ice cube...
