NO! there wasnt much of elecrticity yet.
no they didnt
they used raw (coarse) sugar and raw honey, syrup and treacle.
For armor and weapons.
Douchemarks
People stopped fires in the 1800s by dousing them with water. They didn't use anything to stop tornadoes because that is impossible.
Asbestos is a naturally occurring mineral, and has been in use a LONG time. There was even a mention of a type of cloth in Roman times that could be cleaned by throwing it into a very hot fire- the dirt burned away, leaving clean cloth- asbestos. In the 1800s, the steam engine was coming into use. Asbestos was used as insulation on boilers and steam lines. It was also used as an early electrical insulator.
You use radiation in microwaves
microwaves are used to warm or cook something. the electricity powers the microwave so it will create heat. First use was by the military -- RADAR
the waves are sent to satelites orbiting the earth when you use a mobile
Microwaves are radio waves with frequencies above 3 GHz. They are used to communicate great volumes of information over distances up to 100 miles, at data rates up to several hundred megabits per second per carrier. Certain high-power devices use UHF radio waves to boil water and heat meatloaf. They are marketed under the generic name "microwave ovens" and referred to as "microwaves" by the population at large, even though they use radio waves at 2.45 GHz and, technically, fall 550 MHz short of rights to the title.
The prefix "micro-" is used in microwaves to indicate that the wavelength of these waves is in the range of micrometers, also known as microwaves. The term microwaves distinguishes these electromagnetic waves from other types of waves, such as radio waves or infrared waves, based on their specific wavelength range.
Mobile phones use microwaves - similar to those used in microwave ovens (but at much lower power !)
A microwave oven does not use heat to cook food like a conventional oven, instead it uses microwaves to cook the food. The microwaves produce the heat inside the food, thereby cooking the food from the inside out.
no
The first large-scale use of batteries in the early 1800s was their use as a power source for electrical telegraph networks.
No, they used water.
The North used railroads for importing goods.
Microwaves are close to infrared so much of the technology is similar.
