Which of the following statments must be true for a falling object that has been dropped from rest near the surface of earth.
an object falling near the surface of the earth has a constant acceleration of 9.8 m/s2. this means that the: a) object falls 9.8 m during the first second of its motion. b) object falls 9.8 m during each second of its motion. c) speed of the object increases by 9.8 m/s during each second of its motion. d)acceleration of the object increases by 9.8 m/s2 during each second of its motion. e)force of gravity on the object must be 9.8 n.

What color would an object that reflects green and blue light appear to be in white light? a. blue b. cyan c. magenta d. black

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
