2012年四川高考理科综合 物理)(国外英语资料) Collected by oneself Mistakes are unavoidable For reference only In case of error Please correct me! Thanks In 2012, Sichuan college entrance examination, science, Comprehensive Physics Two, the choice [8 items For each question there are four options. Yes, only one option is correct - some have more than one Option correct The total score was 6 points Yes, but not all 3 points 0 points for the wrong choice 14. objects consist of a large number of molecules The following statement is correct A. molecular thermal movement is very intense The greater the kinetic energy of each molecule in an object The intermolecular attraction of B. always decreases as the distance between molecules decreases The internal energy of a C. object is related to the temperature and volume of the object D. only if the outside work is done can the internal energy of an object be increased 15. April 30th this year Mid orbit satellite launched by Xichang Satellite Launch Center Its orbit radius is 2.8 * l07m It is the same as the other The quality of geosynchronous orbit satellites (orbital radius 4.2 x l07m) is compared A. centripetal force is smaller, B. kinetic energy is bigger C. emission velocity is the first cosmic velocity, D. angular velocity is smaller 16. as shown Two coils, a and B, are wound around the core P be A. coil a input sinusoidal alternating current The coil B outputs a constant current The B. coil a inputs constant current The flux of B through the coil must be zero The alternating current produced by the C. coil B does not affect the magnetic field of the coil a When the magnetic field of the D. coil a changes There must be an electric field in the coil B 17. as shown in the diagram of the energy levels of hydrogen atoms Hydrogen atom A. transitions from the n=4 energy level to the n=3 energy level, and the wavelength of the electromagnetic radiation is longer than the transition from the n=3 energy level to the n=2 level B. transitions from th
