if you are conducting the experiment under a fan, switch off the fan to avoid your pendulum bob to swing in different degree. #stainless
The period is the time taken to complete one cycle. In this case it would be three seconds. The frequency of the swing is the inverse of the period. 1/3Hz
A swinging pendulum encounters "friction" called drag in air. It will do so in water, too. It's just that the viscosity of the air is so much less than that of water, so the pendulum moves with a ton more drag in water. It will move much more slowly in water, and will come to a stop dramatically sooner than an identical pendulum swung in air.
..weigh less and the pendulum will swing at a slower rate. It might become more valuable (high mountain areas have less access to fine clocks than many sea level communities).

A simple pendulum will not swing when it's aboard a satellite in orbit. While in orbit, the satellite and everything in it are falling, which produces a state of apparent zero gravity, and pendula don't swing without gravity.
The pendulum will take more time in air to stop completely in comparision with water

if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
This pendulum, which is 2.24m in length, would have a period of 7.36 seconds on the moon.
A Froude pendulum is a simple pendulum suspended in a rotating shaft (taken from: VIBRATION OF EXTERNALLY-FORCED FROUDE PENDULUM, International Journal of Bifurcation and Chaos, Vol. 9, No. 3 (1999) 561-570)

well, you could simply pull it away from its centre of equilibrium (the point where the pendulum is when its stationary), and release it. Then you just count how many seconds it takes to make one complete oscillation. Note, one oscillation isn't the time for the pendulum to swing to the other side, but is the time taken for the pendulum to return to the side it was initially released from.Note: the greater the angle of the swing, the greater the speed with which the pendulum will swing, but in the absence of air resistance, the period should remain the same with the same pendulum, and because air resistance is all around us, when we move through the air, and is proportional to the speed squared, this will begin to effect the result, by slowing down the pendulum. Therefore a pendulum only obeys SHM for smaller displacements from the point of central equilibrium, or another way of putting that is for smaller angles of pendulum displacment.
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.

by adding pennies , it changes the time taken for the oscillations of a pendulum ( for it to swing back and forth ) . This can be adjusted by adding more pennies to the top, which makes the length of the pendulum shorter and thus swinging faster. However , if you want the pendulum to go at a slower rate , then you would add pennies to the bottom.
