Process: - A machine called a pulverizer grinds the coal into a fine powder - The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace - The burning coal heats water in a boiler, creating steam - Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine - The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy - This happens when magnets inside a copper coil in the generator spin - A condenser cools the steam moving through the turbine - As the steam is condensed, it turns back into water - The water returns to the boiler, and the cycle begins again -   Question: suppose if the machine is off happens, how will it affect The amount of energy and coal will be increased..  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - Electromagnet creates magnetic field with electricity - Conductive copper wire is wrapped around a piece of metal - An electric current gets introduced from power source - Flows through the wire - Magnetic field gets created in the wire - And the metal gets magnetized - When turned off it is no longer magnetic.  Question: suppose Lower electrical current happens, how will it affect Smaller magnetic field.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - Water from the ocean washes onto beaches in waves - The waves contain sediment from the ocean - The water and particles in it hit rocks and sand on the beach - The wind and current sometimes push the water and particles harder - Tiny parts of the rocks on the shore come off the larger rocks - The waves pick up sand and small rocks from the beach - The waves go back out into the ocean - The waves carry the new particles with them - Rocks and the beach look a little different.  Question: suppose there is more calm waters happens, how will it affect there will be more waves in the ocean.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - Coal is harvested from a coal mine - The coal is transported either by train or truck to power station - The coal is burned in a furnace - Water is turned into steam in the boiler - The steam is cooled in cooling towers - The steam turns the turbines - The generator makes electricity - The electricity is sent through transformers.  Question: suppose electricity prices might rise happens, how will it affect more people switch to electric fires.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect

Ans: less
