Mention the key scientists contributed in the following realizations and list the years: 1- Electric charges (positive and negative) 2- Coulomb's law 3- Electric field 4- Gauss's law Type your answer and keep everything to less than 200 words.

1- Electric charges (positive and negative) - Benjamin Franklin  in 1742.

2- Coulomb's law: Charles Augustin Coulomb from 1764 to 1772.

3- Electric field:    Michael Faraday -  1821

4- Gauss's Law: Joseph Louis Lagrange was the first to formulate the rule in 1773, followed by Carl Friedrich Gauss in 1867.

Explanation:

The Electric charge: In 1742, an American orator and inventor named Benjamin Franklin designed the positive and negative values of the charge.

Coulomb's law: The theory was first published in 1785 by Charles Augustin de Coulomb, a French physicist who was instrumental and prominent in the advancement of electromagnetism theory.

Gauss Law: Carl Friedrich Gauss developed this law in 1835. It was not released until 1867, However, Classical electrodynamics is based on this law.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.
