: Suppose the PASCO Motion Sensor is calibrated to give correct measurements of position at 20o C, but the actual temperature in the lab room is 22o C. The Motion Sensor works by timing how long a pulse of sound takes to go from the sensor to the cart and back to the sensor, and at 20o C, the speed of sound is 343.15 m/s, but at 22o C, the speed of sound is 344.31 m/s. What effect does this difference in the speed of sound make, and what kind of error is this

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
