It (to notice) in about 1901 that high doses of radiation (can/to cause) an injury in humans. Henri Becquerel (to carry) a sample of radium in his pocket and as a result he ( to suffer) a high localized dose which (to result) in a radiation burn. This injury (to result) in the biological properties of radiation being investigated, which in time (to result) in the development of medical treatments.
Ernest Rutherford, working in Canada and England, (to show) that radioactivity decay (can/ to describe) by a simple equation, implying that a given radioactive substance (to have) a characteristic ‘’half-life’’. He also (to coin) the terms alpha, beta and gamma rays, he (to convert) nitrogen into oxygen, and most importantly he (to supervise) the students who (to do) the Geiger-Marsden experiment which (to show) that the `plum pudding model` of the atom (to be) wrong. The Rutherford, the gold foil experiment (to imply) that the positive charge (to confine) to a very small nucleus leading first to the Rutherford model, and eventually to the Bohr model of the atom, where the positive nucleus (to surround) by the negative electrons.
Текст: various natural disasters often occur in our nature. For example: Earthquake, fire, tsunami, volcanic eruption, etc. During an earthquake, the earth changes its location. Earthquakes occur due to earthquakes at sea or in the ocean. But in some cases people are to blame for example, in a fire. A volcano erupts when a lot of energy builds up inside the earth.
Перевод: различные стихийные бедствия часто происходят в нашей природе. Например: землетрясение, пожар, цунами, извержение вулкана и т. Д. Во время землетрясения Земля меняет свое местоположение. Землетрясения происходят из-за землетрясений в море или в океане. Но в некоторых случаях люди виноваты, например, в пожаре. Вулкан извергается, когда в земле накапливается много энергии.
