PLEASE HELP ASAP 20 POINTS Assignment: Locating the Epicenter Exploration All over the Earth. seismographic stations keep their instrumenis operating all the time. By Uming the arrival of Pwaves and S waves, scientists at each glatlon can tell how far their slallon is from the source of any earthquake. That distance is used as the radius of a circle around the station on a map of the world. The radius is the distance from the center of the circle to any point on the circle. By comparing the distance from several stations, seismologists can locate the earthquake's epicenter. Look at the map. Notice tha, the three circles overlap. The location where they overlap is the approximate eplcenter of the earthquake

Finding the Epicenter Find the length of the radius of each circle. To calculate the radius, divide the distance from the epicenler by 640 km. Selsmograph records were obtained from an earthquake in Central America. Using the information in the table, locate the epicenter on the map. You will need a compass and ruler. On this map. 1 cm is equal to 640 km.​

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?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
