The heat of vaporization of water at 100°c is 40. 66 kj/mol. Calculate the quantity of heat that is absorbed/released when 7. 00 g of steam condenses to liquid water at 100°c.

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.
