2006年南通市高三第一次调研测试 target=_blank（In 2006, the first research test of target = _blank was conducted in gao3, nantong） In 2006, the first research and testing of the first study was conducted in nantong Content management The first 鈪?(choice is a 40 points) An ontology, a total of 10 questions and each question 4 points, a total of 40 points. Each item in the four choices given, some item is only one option right, some item have more than one option right, all right of 4 points, choose the wrong or not a 0 points, choose the right but not the whole 2 points. 1. In the following statements, historical facts are in line with the facts A. Tom discovered electrons by studying cathode rays B. Newton summed up the law of universal gravitation and measured the gravitational constant C. becquerel discovered the atomic structure of atoms by studying natural radioactivity D. Faraday discovered the phenomenon of electromagnetic induction 2. The following statement about electromagnetic fields and electromagnetic waves is correct A. The changing magnetic field must produce A changing electric field B. the frequency of the electromagnetic wave from the vacuum into the glass becomes smaller C. The radio and television stations need to modulate the radio waves The electromagnetic wave is a material 3. Some electric field lines of an electric field are shown as shown in the figure. A and B are two points on the motion path (dotted line in the figure) under the action of electric field forces A. The particles must be moving from point B to point A B. The acceleration of the particle at point A is greater than the acceleration at point B The kinetic energy of the particle at point A is less than the kinetic energy at point B D. The potential of A point in the electric field is higher than that of point B The following statement is true A. A group of hydrogen atoms in the excited state of n = 3 transition to a lower energy level, with a maximum of two frequencies of photons B. Since each
