Consider that you are in an area of Seattle where the wind is blowing at 40 km/h with a temperature of 0 ° C. If you can be mathematically modeled as a cylinder with diameter external of 0.3m and height of 1.70 m. Calculate the number of hot dogs that you need to eat to make up for the amount of energy you lose in heat form for an hour. Note 1: Consider that the external temperature of the clothes is kept constant at 25 ° C. Note 2: Consider a 150 kcal hot dog.
