Solution

1.


\begin{gathered} F\propto(m_1m_2)/(r^2) \\ \\ F=(Km_1m_2)/(r^2) \end{gathered}

2.


\begin{gathered} F\propto rs^3 \\ \\ F=Krs^3 \\ \\ F=1344,r=12,s=2 \\ \\ 1344=k(12)(2^3) \\ \\ K=14 \\ \\ F=14rs^3 \end{gathered}

3.


\begin{gathered} z\propto(x^2)/(y) \\ \\ z=(kx^2)/(y) \\ \\ z=9,x=9,y=6 \\ \\ 9=(k(9)^2)/(6) \\ \\ 9=(81k)/(6) \\ \\ 6=9k \\ \\ k=(2)/(3) \\ \\ z=(2x^2)/(3y) \end{gathered}
