Problem: Process:  - Coal is loaded into the firebox - The boiler produces steam under high pressure - The steam generated in the boiler flows down into a cylinder - Just ahead of the wheels, pushing a tight-fitting plunger, the piston - The piston is connected to one or more of the locomotive&#x27;s wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod - As the piston pushes, the crank and connecting rod turn the locomotive&#x27;s wheels and power the train along - An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive&#x27;s chimney -   suppose there are seasonal changes happens, how will it affect coal is brought to a broiler.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: not impacting any step of the process


Problem: Process:  - Sunlight passes through the glass into the greenhouse - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom - The colder air is then warmed by the floor and the plants.  suppose it has been raining heavily happens, how will it affect the sky is filled with darkness.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: not impacting any step of the process


Problem: Process:  - Salt water is contained in a factory or plant - The water is boiled to a very high tempature - The salt becomes seperated from the water - The salt is removed - The water is able to be drank at this point.  suppose the person is unable to digest happens, how will it affect lower temperature used.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: not impacting any step of the process


Problem: Process:  - Sediment becomes loose from the rest of the soil - The sediment rolls down hill towards a river - The heavy items sink to the bottom - The lighter items float on the top and in convection cycles - As the river flows the sediment is moved - The sediment gets dumped through tributaries into lakes and the ocean - The sediment keeps moving around the world in convection currents.  suppose there is less sediment happens, how will it affect MORE sediment being transported.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A:
directly impacting a step of the process
