Q. What mass (in grams) of steam at 100°C must be mixed with 124 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 37.0°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg, and the latent heat of vaporization is 2256 kJ/kg.

Q. A copper rod of mass m = 1.00 kg rests on two horizontal rails a distance L = 1.04 m apart and carries a current of i = 47.0 A from one rail to the other. A top view and a side view. The coefficient of static friction between rod and rails is μ = 0.610. What are the (a) magnitude and (b) angle (relative to the vertical) of the smallest magnetic field that puts the rod on the verge of sliding?
