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.
