A group of students must design an experiment to determine how the amplitude of a resultant wave pulse changes when two individual wave pulses combine so that destructive interference is observed. Both wave pulses travel toward each other. How should the students produce the individual wave pulses so that total destructive interference occurs? a. Each wave pulse should have the opposite vertical orientation with respect to the equilibrium position of string and have the same amplitude.
b. Each wave pulse should have the opposite vertical orientation with respect to the equilibrium position of string, have the same amplitude, have the same width, and have the same shape.
c. Each wave pulse should have the same vertical orientation with respect to the equilibrium position of string and have the same amplitude.
d. Each wave pulse should have the same vertical orientation with respect to the equilibrium position of string. have the same amplitude, have the same width and have the same shape.

I'm kinda lost ! 1. when marilyn takes her pet dog for a walk, the dog walks at a veryconsistent pace of 0.55 m/s. draw a position-time graph to representmarilyn's dog walking the 19.8 m distance from the front of her house tothe nearest fire hydrant.2. both car a and car bleave school when a stopwatch reads zero. car atravels at a constant 75 km/h, and car b travels at a constant 85 km/h.a) draw a position-time graph showing the motion of both cars. howfar are the two cars from school when the stopwatch reads 2 hrs? calculate the distances and show them on your graph.b) both cars passed a gas station 120 km from the school. when dideach car pass the gas station? calculate the times and show themon your graph.3. the figure below shows the position-time graph showing a shopper'smovement up and down the aisle at a store.a) write a story describing the shopper's movements at the store.b) when does the shopper have a position of 6 m? c) how much time passes between when the shopper enters the aisleand when he gets to a position of 12 m? what is the shopper's averagevelocity between 37 s and 46 s?
