The period depends on both the length of the pendulum and the force due to gravity. They are related by Huygen's law, T = 2π√(l/g). Assuming a gravity of 10Nkg-1 (roughly equal to Earth's 9.81 and a common approximation) it would need to be 2.5/pi2, or about 0.253099 metres.

What is the length of a pendulum whose period on the moon matches the period of a 1.94-m-long pendulum on the earth?
Nice problem! I get 32.1 centimeters.
If the length of a simple pendulum is doubled what will be the change in its time period?
ts period will become sqrt(2) times as long.
Does a short or a long pendulum have a longer period?
The time of swing of a pendulum is T = 2π √ (l/g) where l is the length of the pendulum. As T ∝√l (Time is directly proportional to the square root of l) then, the longer the pendulum, the greater is the period. Therefore longer pendulums have longer periods than shorter pendulums.
The time period of a simple pendulum having infinite length will be?
It would tend towards infinity
What is the relationship between the length of the string of a pendulum and the number of swings?
There's no relationship between the length of the pendulum and the number of swings.However, a shorter pendulum has a shorter period, i.e. the swings come more often.So a short pendulum has more swings than a long pendulum has in the same amountof time.
What is the period of a 0.85m long pendulum?
The period of a 0.85 meter long pendulum is 1.79 seconds.
What is the period of a pendulum that takes one second to make a complete back and forth vibration?
Suppose that a pendulum has a period of 1.5 seconds. How long does it take to make a complete back and forth vibration? Is this 1.5 second period pendulum longer or shorter in length than a 1 second period pendulum?
What is the length of a pendulum whose period on the moon matches the period of a 1.94-m-long pendulum on the earth?
Nice problem! I get 32.1 centimeters.
Discussion of the measurement of gravity by a bar pendulum?
You can use a simple pendulum, measure how long one period takes, then use the formula for a pendulum, and solve for gravitational acceleration.
If a pendulum has a period of 1.5 seconds how long does it take to make a complete back and forth vibration?
A pendulum with a period of five seconds has a length of 6.21 meters.
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.
Why do people with long legs generally walk with a slower stride than people with short legs?
Natural period of a long pendulum is slower than for a short pendulum.
What happen to the time period of pendulum if the mass of bob is changed?
If you make the simplifying assumption that everything except the bob is massless, then the mass of the bob has no effect on the period.
Value of g by simple pendulum?
You can build a simple pendulum - one that has most of its mass concentrated in a small place, at the end of the pendulum. Measure the pendulum's length, and measure how long it takes to go back and forth. Use the formula for the period of a pendulum, solving for "g".
If the length of a simple pendulum is doubled what will be the change in its time period?
ts period will become sqrt(2) times as long.
Does a short or a long pendulum have a longer period?
The time of swing of a pendulum is T = 2π √ (l/g) where l is the length of the pendulum. As T ∝√l (Time is directly proportional to the square root of l) then, the longer the pendulum, the greater is the period. Therefore longer pendulums have longer periods than shorter pendulums.
Which swings more in30 secondspendulum that is 20cm long or one that is 40cm long?
The shorter pendulum has the shorter period.
