Suppose That a Horse Is Standing in Partial Shade

Multiple Choice

Suppose that a horse is standing in partial shade. Solar radiation provides a net intake of energy of 42 milliwatts per minute, and infrared radiation provides an additional net input of 56 milliwatts per minute. Conductive and convective outputs of heat are a combined 308 milliwatts per minute. There is no detectable change in heat from evaporation. Assuming that the horse is maintaining a constant temperature, how much heat must it be generating (in milliwatts per minute) ?

A) 98
B) 210
C) 266
D) 308
