The following passage explains how the fundamental forces were discovered. Which sentences state incorrect information? Select all that apply.
people have known about gravity as a force between
massive objects since before written history, so no one
knows who first discovered it, its mathematical representation was produced by Isaac Newton
Electromagnetism consists of two phenomena: magnetism and electricity, Magnetism has been known
about since before written history, Electricity was experienced through "electric shocks" and certain
electric fish. However, it was merely a curiosity until about the year 1000 when electrical experiments were
first conducted by a number of researchers in and around Baghdad that showed that lightning is a form of
electricity. These experiments culminated in Maxwell's mathematical representation. The atom's strong
and weak nuclear forces were discovered at the same time when we were first able to peer into a nucleus,
The strong nuclear, weak nuclear, and electromagnetic forces are all mathematically described by the
standard model

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?

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?
