The second law of thermodynamics states that
when a process converts energy from one form to another, some energy converts into heat, a less usable form of energy
energy can neither be created nor destroyed, but can change from one form to another
energy flows through ecosystems without being recycled
most energy in ecosystems comes from the sun

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.
