Draw a model that shows the orbits of the Moon and Earth around the Sun. The model, which does not have to be drawn to scale, should show all the gravitational forces acting on each body and the forward momentum of Earth and the Moon

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.
