Water is boiling in two different size pots. one has a diameter of 0.3 m and the other has a diameter of 0.1 m. if they both have a surface heat flux of 700 kw/m2, how much water has evaporated in 2 min in each case? if the larger pot has twice as much water as the smaller pot, what is the ratio of total time for all the water to evaporate in the larger pot compared to the smaller pot?

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
