Question

Hic mình đang cần gấp lắm, mn giúp mình với ạ :<

Answer 1

\(F_A=P-F=18-10=8N\)

\(V=\dfrac{F_A}{d}=\dfrac{8}{10000}=8\cdot10^{-4}m^3\)

\(d=\dfrac{18}{8\cdot10^{-4}}=22500\)N/m³

Answer 2

\(F_A=P-P'=18-10=8N\)

\(V=\dfrac{F_A}{d}=\dfrac{8}{10000}=8\cdot10^{-4}m^3\)

\(d=\dfrac{P}{V}=\dfrac{18}{8\cdot10^{-4}}=22500\left(\dfrac{N}{m^2}\right)\)
