Radioactive decay

Man and environment are inter-related. The environment influences the life of human beings and also human beings modify their environment as a result of their growth, dispersal, activities, death and decay etc. Thus all living beings including man and their environment are mutually reactive affecting each other in a number of ways and a dynamic equilibrium is possible in between the two, i.e. human beings (society) and environment are interdependent. The different social structures like…

We live in times of fear and uncertainty; where it’s possible you won’t have enough money to pay for the months consuming electric, heat, and water bills. But that’s why nuclear energy has been available in the United States since the 1960’s… because it was needed. And here’s three reasons why: First is the realisation of the increase of the electricity demand worldwide, but especially in rapidly-developing countries. Secondly, is awareness of the priority of energy security, and thirdly is the…

directed by Marc Webb; his background is in short films and music videos, but many would agree that he did a fantastic job on only his second major motion picture. In this film, one of the many reboots of Stan Lee’s original Marvel comic books, a radioactive spider bites Peter Parker and allows him to develop superpowers that he uses to help New York City stay safe. That’s not all though, there are also giant evil lizards walking around that have a vendetta for the web-slinging hero. Many have…

such as; temperature, access by insects, humidity/aridity and rainfall, etc. (Mann, et al., 1990). Cold environments, like the one in which Ötzi was found, inhibit the growth and action of microorganisms and due to the extremely low temperature, the decay process is greatly reduced (Cantor,…

In the year 3000 the world was beautiful, people everywhere, babies being born, the latest fashion trends are on a role, celebrities in the tabloids and on t.v, but all that was changing within 50 years. More predictions of the world ending happen every 3 to 5 years, like in 2008 they believed the world was going to flood and in 2014 the world was suppose to be destroyed but what they didn’t know was that there was going to be an end to the human society. I am Hailey the year is 3056 I…

cost of fossil fuel and natural gasses. Biggest plus point is that it is sustainable; as the energy is produced by a chain reaction and radioactive decay (most used elements have a half-life of at least a few centuries). This means that we won’t suddenly run out of nuclear energy source like natural resources. Nuclear energy is sustainable; we have enough radioactive elements to serve hundred percent of the worlds energy needs for at least the next few hundred years. Because most elements used…

Stop 1: Chimpanzee, Modern Human, and Neandertal Skeleton 1. The modern human skeleton is much larger in size compared to the chimpanzee and hominid skeleton. The Chimpanzee had longer arms, much narrower rib cage and smaller skull compared to both ancient hominid and human. On the other hand, the hominid had robust bone joints, allowing more flexibility. The skeleton structure of chimpanzee indicates that they moved by using four limbs while both human and hominid walked upright. 2. The…

and weak. The electromagnetic force is the reason why the electrons are repelled from the nucleus and the protons. The strong force is why the protons stay together in the middle. These both keep the atom from falling apart. Weak forces keep radioactive decay from transforming the nucleus into a proton or an electron. Most commonly know is gravity. Gravity impacts the less on the atom compared to the rest of the forces. Gravity affects the tiny nucleus slightly. The overall energy inside the…

World War II began on September 1, 1939. At approximately this time, American physicists discovered that splitting atoms can cause a powerful explosion. Though the atomic bomb was not existent until later in the war, well respected, American physicists believed atomic bombs could be produced. They also believed that the bombs could demolish a large city with one, single blast. As the war progressed, rivalries grew more intense and the first atomic bomb was developed. Albert Einstein was one of…

Combustible energy- Combustible energy is a natural form of energy that has been formed and is continuing to be made over millions of years from organic matter. These are generally in the form of fossil fuels and come in 5 main forms: Coal, Petroleum, Natural Gas, LPG (liquified petroleum gas and crude oil. The method that is used to extract usable energy from combustible energy is by putting it through a fossil fuel power station. In these power plants, fuels are burnt to produce steam which…
