My Notes 9. -11 points A thermometer is removed from a room where the temperature is 21° C and is taken outside, where the air temperature is -12° C. After one-half minute the thermometer reads 11° C. what is the reading of the thermometer at t = 1 min? (Round your answer to two decimal places.) How long will it take for the thermometer to reach -8° C? (Round your answer to two decimal places.) min My Notes 9. -11...
A thermometer is taken from a room where the temperature is 20°C to the outdoors, where the temperature is 2°C. After one minute the thermometer reads 11°C.temperature after one more minute ?
A thermometer reading 7 degrees C is brought into a room with a constant temperature of 29 degrees C. If the thermometer reads 15 degrees C after 4 minutes, what will it read in 6 minutes? 11 minutes? So I guess I need to put into newton's law of cooling:u(t) = T + (u sub zero - T ) e^ktHow do I solve for k so can plug in my T's. and what is u sub zero? 7 degrees?
A thermometer reading 8°C is brought into a room with a constant temperature of 35°C (a) If the thermometer reads 15°C after 2 minutes, what will it read after being in the room for 4 minutes? For 9 minutes? b) Graph the relation between temperature and time. Use TRACE to verify that your answers are correct. A pizza baked at 450°F is removed from the oven at 6:00 PM into a room that is a constant 73oF. After 5 minutes,...
Please show all work. Suppose there is a tank of 100 gallons of a salt mixture with concentration 0.25 pounds per rate of 2 gallons per minute. It is well mixed and then drained out at the rate of 2 gallons per minute. A) Write a differential equation, in terms of only A and t, that models this situation, where A is the amount of salt in tank after t minutes. Include the initial condition. DO NO1T SOLVE THE DE!...
