  2. ... communicate using electromagnetic (EM) waves of frequency from 900 MHz to 2100 MHz. EM waves travel by mutual interaction...

  3. ... count rate = 100 - 60 = 40 counts per min From noon to 3 pm, total number of half-life ... 1/8 = 5 counts per min So, the expected count rate at 3 pm = corrected count rate + count...

  4. ... mass starts at the equilibrium position (i.e. at t= 0 ), because we would expect x = 0 when t = 0, ψ should take the value of zero. The general equation thus...

  5. ... up not the merit. Suddenly, dark clouds blocked from the sun, the gale have blown. Expected wind and rain must arrive. The space this time piled up with the black...

  6. ...-Vavilov Rule, which states that photon emission is expected in appreciable yield only from the lowest excited state, If the difference in energy levels...

  7. ... such, the point of "zero gravity", where the gravitational forces from the earth and moon balance one another, is expected to be at location close to the moon. ------------------------------------ Clearly, propulsive...

  8. ...every 0.5 m. At 1 m distance, bcause the particle is going downward from the equilibrium position, you would expect the wave trough is coming to the 1-metre position. Hence...

  9. ... what was given by the answer is right, then we would expect there is sound emitted from a balloon (which is filled with air, hydrogen or helium), as collisions...

  10. 因為實驗被執行在室溫, 冰獲取熱從周圍。因此, 水大量被收集在燒杯比冰的融合期望的和(若具體潛熱) 變得小比被接受的價值大的。消滅這個作用, 控制實驗被設定。實驗開始當二個漏斗的滴水率是相同。
