Part IV: Interference Trial 1
1. With one person on each end, stretch the spring to about three meters.
2. The third member of the group should set a plastic cup at the center of the
slinky approximately 1 foot away from spring. (See diagram)
3 Each person at the end of the slinky will generate a
pulse on the same side of the slinky at the same time by quickly flicking
his/her wrist from side to side.
4 Does the wave hit the cup?
Trial 2
5. Repeat steps 1-2.
6. Each person at the end of the slinky will generate a pulse on the opposite sides of the slinky at the same
time by quickly flicking his/her wrist from side to side.
7. Does the wave hit the cup?
Observations:
Trial 1: What happened to the size of the wave when
the two pulses met?
Trial 2: What happened to the size of the wave when
the two pulses met?

In Trial I of Part IV, what kind of interference is observed? How do you know?

Abearing is designed to a reduce friction b. support a load c.guide moving parts such as wheels, shafts and pivots d. all of the above

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
