a) 10^9
b) 10^8
c) 10^7
d) 10^10
​

Answer 1

Answer:

10^10

Step-by-step explanation:

10^10 = 10000000000

Answer 2

Answer:

The correct answer will be -

(a) $10^9$ seconds

Step-by-step explanation:

About quartz crystal clocks-

• These are used to measure time
• These are one of the highly accurate clocks with an accuracy of 1 second in every $10^9$ second.
• It works on the principle of the piezoelectric effect.
• In the piezoelectric effect an oscillating electro motive force develops in one pair of faces of the crystal when a variable pressure is applied on the other face of the crystal perpendicular to the first one.
