In the figure below, equipotential lines are shown at 1-m intervals. Suppose that V1 = 5 V, V2 = 10 V, V3 = 15 V, V4 = 20 V, and V5 = 25 V. 1) What is the electric field at point A? Enter a positive value if the electric field points in the +x direction and a negative value if the electric field points in the -x direction. (Express your answer to two significant figures.) 2) What is the electric field at point B? Enter a positive value if the electric field points in the +x direction and a negative value if the electric field points in the -x direction. (Express your answer to two significant figures.)

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?
