They determine the length of time of the pendulum's swing ... its 'period'.
The theory of a simple pendulum refers to a relatively huge object hanging vertically by a string from a fixed place and moving in a back and forth motion when displaced. The movement of the huge object or pendulum bob is repetitive and regular.
A torsional pendulum exhibits rotational periodic motion. You can create one by hanging some weight from a cord, and then rotating the weight. The cord becomes twisted, generating a torsion force, that will cause the weight to rotate in the oppopsite direction. Thus, a periodic rotation movement is generated.
Many wall clocks function from an internal gear that keeps the time smooth, yet erratic. However, clocks that incorporate a pendulum are much more accurate. The reason is that pendulums always have a set period regardless of the cord length, thus by the laws of physics they are subject to remain at a constant beat and keep tie extremely efficiently. In addition, a pendulum functioned wall clock is very quiet and offers a sense of silence unlike that of its gear operated counterpart.
Make the pendulum longerMake the pendulum heavierMake it swing in a vacuumLubricate the pivot point to reduce frictionItem 1 is the only way to make the "period" longer. The period being the time to complete a cycle. The other suggestions will make the pendulum swing for a longer time but will not affect the period.
Wiki doesn't do your homework, so it is time to get busy. OH yeah that's what i said oh yeah u tokd him/her (whoever asked this question)
The period of a pendulum can be made longer by lengthening the cord or stick that connects the weight and the pivot. (Assuming that you cannot change the force of gravity.)

Length and wire gauge will determine this for you...
An ideal (simple) pendulum has ONE mass, and a massless cord that sustains it.
A torsional pendulum exhibits rotational periodic motion. You can create one by hanging some weight from a cord, and then rotating the weight. The cord becomes twisted, generating a torsion force, that will cause the weight to rotate in the oppopsite direction. Thus, a periodic rotation movement is generated.

Normal length of an umbilical cord can range from a couple feet in length to less than one foot, it all depends on the particular pregnancy.
The radius is a cord, is it not?
Tension = mass(acceleration) + force of gravity Force of gravity equals mass times gravity (9.8m/s2)

A full cord is 4fthigh x 4ftwide x8ft in lengthA face cord is 4fthigh x 8ft in length and it's width is the length of the wood pieces (usually 16-18 inches)
The Norelco Reflex 7310 XL shaver is a cordless razor,so the cord has zero length.
