in a car engine, energy is converted in a number of ways to make the car run. identify the correct order of the energy conversion in the engine of the car by this path:

the ignition switch is turned, which sends a signal to start the car by fuel burning. this gets the engine going, which produces heat. when the driver puts the car in drive and pushes the accelerator, the car starts moving.

question 2 options:

heat --> chemical --> mechanical --> electrical

mechanical --> electrical --> heat --> chemical

electrical --> chemical --> thermal --> mechanical

chemical --> mechanical --> heat --> electrical

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback

How does an observation about an object differ from an inference about that object

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
