In the 21st Century there are several energy production methods, they can be cheap yet inefficient or expensive and more efficient. However, fossil fuels are used because they are efficient and easy to acquire, but they affect the environment. Coal-Fired electricity production has been around since the Industrial Revolution, this means that coal-fired electricity that still makes up 61% of the electricity produced in Australia (Department of Industry and Science, 2015).

Another reason, by 22 weeks the baby is technically able to live outside the womb. The baby will struggle if born at 20 weeks because he/she isn’t ready to live outside of the womb yet. But 9 out of 10 of the babies born at 20 weeks survive. At 24 weeks all of the baby’s organs are fully developed. By 18 weeks he or she can hear the mother’s heartbeat and sounds outside of the body. How could someone kill a fully developed baby, let alone one at all? However, there are many different procedures…

brain of human being. It’s an electronic computing machine-a brain, if you like. This chamber alone, the smallest of the thirty-nine used, contains enough wire to reach from here to the moon four times. There are more vacuum tubes in the entire instrument than there were vacuum tubes in the State of New York before World War II.

He discovered the electron through a series of experiments. The experiments were designed to study the nature of the electric discharge in a high-vacuum cathode ray tube. As thomson conducted the experiment he noticed some anomalies. He interpreted the anomalies as the evidence of smaller bodies that are far smaller than the atom. The discovery of the atom had drastic impacts on the world. The discovery led…
