You're outdoors in the winter and the temperature is 5 °c. as you breathe, show a schematic of the process for air between state 1 and state 2, where state 1 is at the entrance of your nose and state 2 is at the exit of your trachea. also, represent the process (approximately) on a t-u diagram.

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
