1)The Spinning Jenny was invented to make the spinning of cotton faster during the industrial revolution
2)Wood plows couldn't plow the rich soil of the Middle-West and kept breaking when being used so the steel plow solved this problem
3)The steam engine helped to power the Industrial Revolution. Before steam power, most factories and mills were powered by water, wind, horse, or man. Water was a good source of power, but factories had to be located near a river. Both water and wind power could be unreliable as sometimes rivers could dry up during a drought or freeze during the winter and wind didn't always blow. Steam power allowed for factories to be located anywhere. It also provided reliable power and could be used to power large machines
4)Cotton gin is used to remove the cotton seeds from the cotton
5)Electrical telegraph networks permitted people and commerce to transmit messages across both continents and oceans almost instantly, with widespread social and economic impacts thus becoming the first form of electrical telecommunications.
6)The mccormick reaper is a farm implement or person that reaps (cuts and often also gathers) crops at harvest when they are ripe and made harvesting crops much easier
7)Dynamite is mainly used in the mining, quarrying, construction, and demolition industries and it was a more powerful alternative to black powder.
