Answer 1

Answer:

Atomic clocks are actually quartz clocks—just like the ones you have at home. The difference is that an ordinary quartz clock relies purely on the oscillations of its quartz crystal to count seconds.

Answer 2

Answer:

lcm (3,7,12,14) =84

84 sec = 1 min 24 sec

the next toll together is 12:01 24 sec

14 min =840 sec

so they do so 10 times in 14 min
