    Black Hole Research Paper

    • 22 Pages

    Could a Black Hole Destroy Earth? Black holes do not wander around the universe‚ randomly swallowing worlds. They follow the laws of gravity just like other objects in space. The orbit of a black hole would have to be very close to the solar system to affect Earth‚ which is not likely. If a black hole with the same mass as the sun were to replace the sun‚ Earth would not fall in. The black hole with the same mass as the sun would keep the same gravity as the sun. The planets would still orbit

    adioisotopes: What Are They and How Are They Made?What are isotopes?The isotopes of an element are all the atoms that have in their nucleus the number of protons (atomic number) corresponding to the chemical behavior of that element. However‚ the isotopes of a single element vary in the number of neutrons in their nuclei. Since they still have the same number of protons‚ all these isotopes of an element have identical chemical behavior. But since they have different numbers of neutrons‚ these isotopes

    by scientists in the nineteenth century. The atomic theory of matter was first proposed on a firm scientific basis by John Dalton‚ a British school teacher in 1808. His theory‚ called Dalton’s atomic theory‚ regarded the atom as the ultimate particle of matter (Unit 1). In this unit we start with the experimental observations made by scientists towards the end of nineteenth and beginning of twentieth century. These
