  1.2Vmax
  2.Vmax
  3.Vmax/2
  4.Vmax/2
  5.Vmax/4



[Ques. 4] Define texture.



[Ques. 5] How does the rate of cooling affect grain size?

  5.Vmax/4



[Ques. 7] What is the common name for pyrite (FeS2)?



[Ques. 8] A capacitor and a resistor are connected in series across an AC generator as shown in Figure OQ33.3. After the switch is closed, which of the following statements is true?
 
  1.The voltage across the capacitor lags the current by 90.
  2.The voltage across the resistor is out of phase with the current.
  3.The voltage across the capacitor leads the current by 90.
  4.The current decreases as the frequency of the generator is increased, but its peak voltage remains the same.
  5.None of those statements is correct.



[Ques. 9] Distinguish between the micas, biotite, and muscovite.



[Ques. 10] A resistor, a capacitor, and an inductor are connected in series across an AC generator. Which of the following statements is false?
  1.The instantaneous voltage across the capacitor lags the current by 90.
  2.The instantaneous voltage across the inductor leads the current by 90.
  3.The instantaneous voltage across the resistor is in phase with the current.
  4.The voltages across the resistor, capacitor, and inductor are not in phase.
  5.The rms voltage across the combination of the three elements equals the algebraic sum of the rms voltages across each element separately.
