### What is the length of simple pendulum which ticks seconds?

What you want is a pendulum with a frequency of 1/2 Hz. It swings left for 1 second, then right for 1 second, ticks once in each direction, and completes its cycle in exactly 2 seconds. The length of such a pendulum technically depends on the acceleration due to gravity in the place where it's swinging. In fact, pendulum arrangements are used to measure the local value of gravity. A good representative value for the…

### Cloud the pendulum be changed to increase the period of the pendulum?

Yes. You can increase the period by moving the pendulum to a location where the gravitational force is weaker. Alternatively, you can increase the effective length of the pendulum. The pendulum may be of fixed length, but you can still increase its effective length by adding mass to any point below its centre of gravity.

### How is the period of the pendulum affected by its length?

the time period of a pendulum is proportional to the square root of length.if the length of the pendulum is increased the time period of the pendulum also gets increased. we know the formula for the time period , from there we can prove that the time period of a pendulum is directly proportional to the effective length of the pendulum. T=2 pi (l\g)^1\2 or, T isproportionalto (l/g)^1/2 or, T is proportional to square root…

### If the length of a pendulum increases what does the period of the pendulum do?

The period of the pendulum increases, i.e. the pendulum swings fewer times in an hour. The time period of a pendulum is directly proportional to the square root of its length. So, if the length increases, its time period also increase. ie. It takes longer to complete one oscillation T = 2Ï€âˆš(l/g) T = Time period l = length g = acceleration due to gravity

### How you can use a simple pendulum to measure the pulse rate?

Pulse and pendulum According to his first biographer Viviani, Galileo experimented with synchronizing two clocks -- the human pulse, and a pendulum -- in his student days at Pisa. The resulting invention, the "pulsilogium", represented the pulse rate as the length of the pendulum. Try making a pulsilogium: adjust the length of a pendulum so that its rate of swinging agrees with your own pulse. Mark the length. Then adjust the same pendulum for your…
