理科综合能力测试⒂(物理部分)（Science comprehensive ability test, (Physics)）

理科综合能力测试⒂(物理部分)（Science comprehensive ability test, (Physics)） I carefully collated documents, documents from the network I only collect and sort out In case of error Please check it yourself! Comprehensive ability test of Science (23) (physical part) 13. the following statement is incorrect The greater the A. gas pressure is The greater the average kinetic energy of a gas molecule B. in the adiabatic process External action on gases The internal energy of gases is sure to increase C. temperature rise The thermal motion rate of each molecule does not necessarily increase in an object D. the macroscopic processes involved in thermal phenomena in nature are directional 14. radioactive decay has many possible ways One way is to become the first That can be changed by one decay (X stands for some element) It can also be converted into decay at one time And finally become The decay path is shown In the diagram A.a =81 B = 206 B. is beta decay Electron emission Electrons are produced by the conversion of neutrons into protons C. II is beta decay Electron emission Electrons are produced by the conversion of neutrons into protons D. can be transformed by 8 beta decay and 8 alpha decay 15. a simple harmonic wave The waveform in a moment a is shown in Figure The timing starts at this hour The vibrational picture of the A particle on the wave is shown in Figure B. be If the A. wave meets another column shear wave and harmonic stable interference phenomenon The frequency of the wave encountered by the wave is 2.5HZ B. if the wave can produce an obvious diffraction phenomenon The size of the obstacles encountered by this wave must be much larger than that of 20m C. from this moment onwards Go through Delta t=0.4s again The distance traveled by P is 4m D. from this moment onwards The particle P will go back to the equilibrium position than the particle Q 16. He Ne laser emits a laser with a wavelength of 663nm The output power of the laser is 1mW The Planck constant is known to b
