A simple pendulum of length 20cm took 120 seconds to complete 40 oscillation find its time period?

The period of a simple pendulum of length 20cm took 120 seconds to complete 40 oscillation is 0.9.


What are two factors that alter the oscillation period of a pendulum?

1. Length of the pendulum 2. acceleration due to gravity at that place


Explain how the length of a string affects the motion of a simple pendulum?

You mean the length? We can derive an expression for the period of oscillation as T = 2pi ./(l/g) Here l is the length of the pendulum. So as length is increased by 4 times then the period would increase by 2 times.


If a pendulum takes 32 seconds to complete 20 oscillations. Calculate the time period?

Time period per oscillation=32/ 20=1.6 sec per oscillation.


What is the formula of time period for projection of particle?

time taken by pendulum/to complete 1 oscillation


How does the period of the oscillation vary with its length when the length increased?

The period increases too.


Does the time period of oscillation depends on the displacement from the equilibrium position?

If you're thinking about a pendulum but not mentioning it, then no, it doesn't


Why a compound pendulum is called equivalent simple pendulum?

Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.


What effect does decreasing the weight of the bob have on the period of the pendulum?

The weight of the bob will determine how long the pendulum swings before coming to rest in the absence of applied forces. The period, or time of 1 oscillation, is determined only by the length of the pendulum.


What was the period of the oscillation of the pendulum in 1851?

Same as it was in 1751, and same as it will be in 2051. Here is a link to an overview of pendulum calculations: http://en.wikipedia.org/wiki/Pendulum_(mathematics)
