Question:

Newton's Law of Cooling states that the rate of change of the temperature of an object, T, is proportional to the dT difference

Newton's Law of Cooling states that the rate of change of the temperature of an object, T, is proportional to the dT difference of T and the temperature of the region, Tror = k(T-TR). An object with core temperature of 1200°F is dt removed from a fire and placed in a region with a constant temperature of 80°F. After 1 hour, its core temperature is 830°F. What is the object's core temperature 4 hours after it is taken off the fire? (1 point) 370.4010°F 305.2214°F 225.2214°F 145.4010°F

Part A The Concorde was a supersonic aircraft used for trans-Atlantic travel in the 1980s and 1990s, having a length of 61.6 m when sitting on the ground on a typical day when the temperature is 14.0°C. The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 29.0 cm. (The passenger cabin is on rollers, so the airplane expands around the passenger cabin.) Take the coefficient of linear expansion for aluminum to be a = 2.40x10-5 /°C. What is the temperature T of the Concorde's skin in flight? View Available Hint(s) IVO AXO ? T = °C
