For small amplitudes, the period can be calculated as 2 x pi x square root of (L / g). Convert the length to meters, and use 9.8 for gravity. The answer will be in seconds.
About 1.4 seconds.

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.
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".
What is the period of a 0.85m long pendulum?
The period of a 0.85 meter long pendulum is 1.79 seconds.
A simple pendulum is 5.00 m long What is the period of simple harmonic motion for the pendulum if it is placed in a truck that is accelerating horizontally at 5.00ms2?

What is the length of pendulum on moon if on earth is 1 m?
It is assumed that the question asks "for the same period". The period of a simple pendulum, for "very short swings", is 2 pi (L/G)0.5. Since G on the moon is 0.165 that of Earth, L would have to be 0.165, so that 1 m pendulum would have to be about 0.165 m long in order to give the same swing period.
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.
What is the period of a 0.85m long pendulum?
The period of a 0.85 meter long pendulum is 1.79 seconds.
The time period of a simple pendulum having infinite length will be?
It would tend towards infinity
What is the period of a simple pendulum 80 cm long on the earth and when it is in a freely falling elevator?
In a freely falling elevator, there would be a period of infinite length, because in freefall, the objects act as if there is no gravity. On earth, the period is given as the quantity 2pi times the square root of the quantity length/g. g is the gravitational constant, which is 9.8 on earth. The period of the pendulum does not depend on how far you pull it back, or how much mass is on the pendulum. Both are common misconceptions. I don't have access to a calculator now, but I will come back to add the actual answer later. Use the formula within the explanation.
What is the period of a simple pendulum 80 cm long a- on earth and b- when it is in a freely falling elevator?
none. when there is gravity T=2pi square root of L/g but in a freely falling elevator, there is no accelerate so it doesn't have period the answer is none

What changes to the bob of a simple pendulum can be made without affecting the time period?
Its mass (weight) can be made anything you want. As long as the bob weighs significantly more than the string that suspends it, and as long as air resistance can be ignored, nothing you do to the bob has any effect on the period of the pendulum's oscillation.
What is the length of pendulum on moon if on earth is 1 m?
It is assumed that the question asks "for the same period". The period of a simple pendulum, for "very short swings", is 2 pi (L/G)0.5. Since G on the moon is 0.165 that of Earth, L would have to be 0.165, so that 1 m pendulum would have to be about 0.165 m long in order to give the same swing period.
How is the the time period of a pendulum affected when the bob of the simple pendulum is filled with mercury?
Answer #1:Your question cannot be answered without knowing what the pendulum wasfilled with before it was filled with mercury.If it had nothing in it, before, then adding the mercury would increase theperiod time.If it had lead in it before, then adding the mercury would decrease the periodtime.================================Answer #2:The period of a simple pendulum doesn't depend on the weight (mass) of thebob. As long as the bob is much heavier than the string, and air resistance canbe ignored, nothing you do to the bob has any effect on the period.
