Q1. A beam of parallel rays from a 33 MHz citizens band radio transmitter passes between two electrically conducting (hence opaque to radio waves) buildings located 44 m apart. What is angular width of the beam while it emerges from between the buildings?

Q2. A blacksmith drops a 0.75 kg iron horseshoe into a bucket containing 25 kg of water.

If the initial temperature of the horseshoe is 450 °C, and the initial temperature of the water is 45° C, what is the equilibrium temperature of the system? Presume no heat is exchanged with the surroundings.
