A.silicon dioxide
B.germanium oxide
C.a mixture of germanium oxide and silicon dioxide

Answer 1

(A) is the answer Silicon DiOxide.

Answer 2

Quartz crystals normally used in quartz clocks are silicon dioxide.

Option: A

Explanation:

• The working of Quartz is usually by a crystal oscillator. The Silicon dioxides are the crystals which are piezoelectric and can be further used as speakers and microphones.  

• Whenever we pass the electricity via quartz it will get vibrated at a provided frequency which will not change enough with the temperature.

• When we placed this in amplifier, it will create a sound. This frequency will be depending upon the cut and placement of the crystal and electrodes respectively.
