It makes life much more convenient for busy families. For instance parents that work late shifts or children that have sports practice. (www.quora.com) Cons: Like I’ve said microwaves have made it easier to cook food its also made it cheaper. Being able to eat a hot meal within minutes has allowed people to eat at anytime without putting forth any effort. Now a days you have isles specifically made for frozen meals.
Microwaves use radiation to cook your food, and surprisingly, this radiation “has enough energy to damage DNA and cause cancer” (Rolfo). If these radiation waves stayed inside the microwave, then there wouldn’t be a problem, but they don’t. When radiation enters your body, it does not eventually go away, but instead, it builds up over time until your body cannot cope with the amount of radiation. It is important to realize that “each exposure to radiation builds up in our body and the risk of cancer increases with each radiation exposure” (Bromberg and Covarrubias). Throughout your lifetime, as you are exposed to this radiation from your microwave, it slowly adds up and increases your risk for cancer.
Effects of Cell Phones Everybody knows how technology has changed our lives and made it easier than before. One of the most important technologies is a cell phone. Cell phones have made our lifestyle completely different. In the past, there were difficulties in communicating with people who live in far away places. Knowing our friends news is one of the many benefits of cell phone.
Cell Phones are good for research because if there is something to research in class they can do it so they can know what the meaning of something is or to research something for a homework assignment or a project. Many parents buy us cellphones because they want to prepare us for adulthood and responsibilities. Another thing, is that they are good for emergencies because you never know when there is going to be a shooting, stabbing, or kidnapping at school. Also, cellphones are good for safety because if you end up in a shooting at school you can immediately call 911. Kids can use phones in school while there are in class because if they forgot a calculator at home they can use their device and use the calculator on there.
Telegraphs weren't nearly as useful as the telephone but that came in later on. Railroads for example used telegraphs a lot because they needed to be able to communicate rapidly between other stations. This allowed railroads to operate more effectively. The market revolution was everything but big. Even though the market revolution was criticized by a lot of people, it was a remarkable step towards a strong and stable economy in United States.
In addition, nuclear power can help us produce electricity, which is required in different fields all around the world. Moreover, It is used to diagnose diseases in the hospitals by using its radioactivity. It can be used for bad purposes such as terror activities. Some countries are using it to produce a wiping that can kill a million of
The magnetic field induces the whirling electrical currents inside the pan and it is turning into a heater. The heat from the pan flows directly into the food or water inside it by conduction. If you already know the concept of physic science, you will be known and used to know more about the conduction. Yes, the principle of conduction that uses in induction cooking. The usage of each material as if the iron material in the cooktops is the example of how the conduction happens and flow from the metal to the food.
Cell phones are a good way of communication. While Cell phones have advanced in amazing ways since their inception, there are many concerns about their safe use. Cell phones have also changed our world because they add mobility, cheaper long distance calling, advanced technology, and evolving
The original purpose of a phone was to be able to communicate to people with ease. Today, society has shifted the ideal purpose of a cell phone. Its ability and purpose has changed in a way so unexpected no one dared to look back at the old technology they used before. But as its need in society grew, people began to question whether it is a tool or a toy. Essentially it is both, but people can not see that.
Microwave heating is unique and offers a number of advantages over conventional heating such as: (a) non-contact heating, (b) energy transfer rather than heat transfer, (c) rapid heating, (d) material-selective heating, (e) volumetric heating, (f) quick start-up and stopping, (g) heating from the interior of the material body, and (h) higher level of safety and automation . Several studies have shown that microwave heating is a good alternative for carrying out the pyrolysis of biomass including oil-palm stone , wood , coffee hulls , waste tea , sawdust , wheat straw , rice straw , corn stover , oil palm biomass , and microalgae . Generally, the differences between the microwave and conventional heating can be attributed to the different heating mechanisms (dielectric heating vs. convection and conduction) and to the occurrence of a phenomenon referred to as hot spots (sparks)
