substitution is the type of mutation that occurred
Answer: Part A the right sentence is: 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
Part B. aproximatelly 98 times ΔV V
Part C. the initial kinetic energy of the proton is 1.87 10^3 eV
Explanation: Part A. The field stops the proton so the lines of electric fild must be directed in opposite direction of its movement. This means that the proton moves to a higher potential. Part B The kinetic energy of the is transformed in electric potenctial for the proton.
Part C. Energy in J divide the charge of electron gives the energy in eV.
Answer:
this is just a guess bc i only looked at it for 5 seconds but i think 150 m/s
