Answer 1

$\frac{d_2}{d_1}=5=>d_2=5d_1\\ h_1=1 cm=0,1 m\\S_1=\pi r_1^2=\pi (\frac{d_1}{2})^2\\S_2=\pi r_2^2=\pi (\frac{d_2}{2})^2 \\V_1=V_2\\S_1h_1=S_2h_2<=>\pi (\frac{d_1}{2})^2h_1=\pi (\frac{d_2}{2})^2h_2|:\frac{\pi}{4}=>d_1^2h_1=d_2^2h_2=>h_2=\frac{d_1^2h_1}{d_2^2}=\frac{h_1}{n^2}=\frac{0,1}{5^2}= 0,004 m=>h_2=0,4 cm$

$p_1=p_2\\\frac{F_1}{S_1}= \frac{F_2}{S_2} <=>\frac{F_1}{\pi(\frac{d_1}{2})^2 }= \frac{F_2}{\pi(\frac{d_2}{2})^2 } |:\frac{\pi}{4}=>\frac{F_1}{d_1^2}=\frac{F_2}{d_2^2}=>F_2=\frac{d_2^2*F_1}{d_1^2}=n^2F_1=5^2*200=25*200= 5000 N=>F_2=5000 N$
