Which option identifies the step analogous to evaluating solutions in problem solving in the following scenario? ChemCo, a small specialty chemical company, sets a benchmark to recycle as much of their chemical waste stream as possible in one year. They gather data about the types and amounts of waste generated and identify what can be recycled. They also study how the large chemical manufacturing companies decide which waste is economically feasible to recycle. ChemCo chooses one of the identified strategies to try. After one year they evaluate the effectiveness of their strategy and realize their benchmarking process was flawed.
Setting a benchmark
Trying an identified strategy for a year
Studying how other companies make decisions

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
