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 -   Perturbation hypothesis: suppose there are seasonal changes happens, how will it affect coal is brought to a broiler.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


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.  Perturbation hypothesis: suppose it has been raining heavily happens, how will it affect the sky is filled with darkness.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


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.  Perturbation hypothesis: suppose the person is unable to digest happens, how will it affect lower temperature used.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


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.  Perturbation hypothesis: suppose there is less sediment happens, how will it affect MORE sediment being transported.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
