Use the formula T = 2Pi * Square root (L)/ Square root (g)
Set T to .75; L is length of string and g is gravity (9.8 m/s)
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 pendulum of a clock is the long weighted bar that swings back and forth in the case below the clock. It was discovered several hundred years ago that the time it takes for one swing of a particular pendulum is constant, no matter how big or small the swing is. It can, therefore, be used to measure time.

Not significantly, unless you start with the pendulum over about 15 degrees or so from the vertical. At large angles the period of the pendulum would increase somewhat, as the restoring force no longer increases linearly with displacement. You will note that clock pendulums generally swing through quite a small angle.
The period of a 0.85 meter long pendulum is 1.79 seconds.
The pendulum clock was the most accurate clock of its time. A disadvantage was that if in the sun too long it would heat up the pendulum and it would change the speed of it.
A pendulum is a piece of string attached to a 20 g mass that if you double the length it will take twice as long to swing.

A pendulum with a period of five seconds has a length of 6.21 meters.
The time it takes a pendulum to complete a full swing is given by the formula: T = 2 pi sqrt(L/g) where L is the length of the pendulum, and g is acceleration due to gravity. With a little algebra we can rearrange this to get: g = (2 pi / T)^2 L So measure the length of your pendulum to get L, then measure how long it takes for a complete swing, plug it into the formula, and there's your acceleration due to gravity. You can try it here on Earth and see what you get.
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.
It's really a long story.In general, the plane of a pendulum's swing rotates in a time equal to[ (24) divided by (sine of your latitude) ] hours.That means 24 hours at a pole, 33.9 hours at 45 degrees, and no rotation at all on the equator.This is happening with any pendulum. Ordinarily, we don't notice it, for two reasons:-- The pendulum has to be free to swing in any direction. A flat stick hanging from a pin can't do that.-- The typical pendulum doesn't swing long enough for the rotation of its plane to become noticeable.
