The number of cm_s in four cm_f is 6 cm_s.The number of cm_t in four cm_d is 6 cm_t.
The number of cm_d in two cm_f is 5 cm_d.

This result is much less accurate than it could have been had the ruler been read to its maximum possible accuracy.

The minimum value of n such that a ruler showing cm_n would be capable of measuring a micron would be cm_24.
The minimum value of n such that a ruler showing cm_n would be capable of measuring an atom would be cm_39.
@&
Both of these answers are close, but neither follows from your reported data.

The previous submitted work from me was for the ruler experiment not the pendulum. This work is for the pendulum.
30 cycles with the short pendulum in 2cm: 27 sec30 cycles with the long pendulum in 2cm: 58 sec
30 cycles with the short pendulum in 5cm: 28 sec
30 cycles with the long pendulum in 5cm: 59 sec
30 cycles with the short pendulum in 10cm: 30 sec
30 cycles with the long pendulum in 10cm: 57 sec"

Good.
However you should have reported your pendulum lengths as well (e.g., width of 8.5 x 11 sheet of paper, 4 times length of same).
