Which answer choice is correct about the pictures? Student 1: The lightning does not belong in the group because it uses human-harnessed energy for electricity. It does not utilize naturally-occurring electricity.
Student 2: The image of the sock does not belong because it is clinging to the clothes due to static electricity, while all of the other images are examples of current electricity.
Student 3: The image of the electrical outlet does not belong because it is the only example of human-harnessed electricity.
Student 4: The image of the sock does not belong because the dryer created the cling, and since humans use electricity to power dryers it is an example of human-harnessed electricity.

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

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
