First take the average of your times:
(12.6 + 12.7 + 12.5 + 12.6 + 12.7) / 5 = 12.62
This is your average time for 20 oscillations. The period is the time for one oscillation, and therefore the period is 12.62/20 = 0.631 seconds.
A complete oscillation is when the pendulum swings from the start position to the opposite position on the swing and back again. Assuming this is what you counted twenty of, then your pendulum is 10 cm long.
If you counted 20 swings to each side, then you really only counted 10 oscillations. This means that your period would be 1.262, and would suggest that your pendulum is 40cm long.

What do the length of the cord and gravity determine for a pendulum?
They determine the length of time of the pendulum's swing ... its 'period'.
How to determine the value of g?
That can be determined fairly easily with a pendulum. The period of the pendulum depends on the length of the pendulum and the value of "g".
What happen to the energy of compound pendulum when it is oscillating?
when oscillations taken energy of pendulum dissipates
What happens to the energy of a compound pendulum when it is oscillating?
when oscillations taken energy of pendulum dissipates
Which oscillations are seen in torsion pendulum?
Circular harmonic motion

What is the significance of the simple pendulum?
The simple pendulum can be used to determine the acceleration due to gravity.
How do you use a pendulum for divination?
It depends on how you were trained. No matter how you were trained, however, you first suspend the pendulum from your hand. Some people determine yes or no from the direction the pendulum spins; others use the speed of the pendulum to determine if a response is positive or negative.
Does the pendulum affected by a force?
no force does not effect the pendulum as it depends upon the oscillations.

How the motion of simple pendulum is affected if it is placed at the center of earth?
If the plumb point of a pendulum is the center of earth, the pendulum will make diametrical oscillations
How can pendulum be used to determine local gravitational acceleration?
Measure the length and the period
A simple 2.80 m long pendulum oscillates in a location where g9.80ms2 how many complete oscillations dopes this pendulum make in 6 minutes?
Answering "A simple 2.80 m long pendulum oscillates in a location where g9.80ms2 how many complete oscillations dopes this pendulum make in 6 minutes
Why it is imp to record 10 oscillations in a pendulum?
I assume you want to get the pendulum's period. If you record a greater amount of oscillations, you will reduce the error - since if you manually measure time, you are likely to get an error of a few tenths of a second.
