Aresearch submarine has a 30-cm-diameter window that is 8.6cm thick. the manufacturer says the window can withstand forces up to 1.2×10^6 n . what is the submarine's maximum safe depth in salt water?

the pressure inside the submarine is maintained at 1.0 atm.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
