em nói hay ghê cuối cùng vẫn làm sai đề :V

hmm tại mình thấy trên đề cho các dữ kiện đó rồi < ko bt có nhầm ko>, nghĩ thì cái này đi tính độ sâu của thuyền ở mỗi điểm trên 

-Lực kế 

-thước đo 

\(p=d_nh\Rightarrow h=\dfrac{p}{d_n}=\dfrac{4000}{10000}=0,4\left(m\right)\)

\(P_A=d_nh_A\Rightarrow h_A=\dfrac{P_A}{d_n}=\dfrac{6000}{10000}=0,6\left(m\right)\)

< Bạn kiểm tra lại đề nhé>

a,Ta có 

\(P_1=d_nh_1=3,02\cdot10^6\left(Pa\right)\)

\(P_2=d_nh_2=0,98\cdot10^6\left(Pa\right)\)

\(P_1>P_2\Rightarrow h_1>h_2\)

Vậy tàu đang nổi lên

b, < đề có lỗi ko bạn ?>

ngược đời thiệt :V
