Ten m^3/s of air at 0ºC, 80% relative humidity is heated to 25ºC. Determine the amount of heat transfer required and the final relative humidity of the air. Determine the amount of water required to increase the final relative humidity to 50% at 25C. How much additional heat is then required to accomplish this humidification?

A 500-turn circular loop 15.0 cm in diameter is initially aligned so that its axis is parallel to the Earth's magnetic field. In 2.77 ms the coil is flipped so that its axis is perpendicular to the Earth's field. If a voltage of 0.166 V is induced in the coil, what is the value of the Earth's magnetic field?
