If you dive into a pool that is 9 ft deep and swim to the bottom, what will the pressure be (in Pa)? (Treat the surface pressure as 101,325 Pa.)

show the diagram then i will answer

i believe the answer is a

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid
