Janis volunteered to participate in a psychology experiment. when she arrives at the lab a lab assistant standing on the other side of a counter greets her. the lab assistant explains the informed consent procedure and asks her to sign the form. as the lab assistant reaches for the form he drops it behind the counter. he drops down behind the counter to pick up the form, but, unbeknownst to janis, another person stands up holding the form. after janis signs the form, she is asked if she noticed the change. she replies that she did not. this phenomenon is known as:

If 21.2 kcals of energy is released by this reaction, how many kj does the reaction release? (1 cal 4.184 j)

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
