You can use a simple pendulum, measure how long one period takes, then use the formula for a pendulum, and solve for gravitational acceleration.

How is bar pendulum better than simple pendulum?
Bar pendulum has lesser air friction while it oscillates to and fro.
What is the meaning of pendulum?
A body so suspended from a fixed point as to swing freely to and fro by the alternate action of gravity and momentum. It is used to regulate the movements of clockwork and other machinery.
What is clock pendulum?
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.

The specific gravity of water is 1.0?
The specific gravity of pure water is 1.0000 at 4 °C and 1 bar. Deviations from this will change the specific gravity. At 0°C and 1 bar, liquid water has a specific gravity of 0.9999 (one of the only substances to EXPAND as it approaches its freezing point). At 100 °C and 1 bar, the specific gravity of liquid water is 0.9584. At 0 °C and 150 bar, liquid water has a specific gravity of about 1.007.

What level of measurement is a bar code?
The level of measurement of a bar code is nominal.
What factors affect the swing of a pendulum?
Air resistance, Gravity, Friction, The attachment of the pendulum to the support bar, Length of String, Initial Energy (if you just let it go it will go slower than if you swing it) and the Latitude. Amplitude only affects large swings (in small swing the amplitude is doesn't affect the swing time). Mass of the pendulum does not affect the swing time. A formula for predicting the swing of a pendulum: T=2(pi)SQRT(L/g) T = time pi = 3.14... SQRT = square root L = Length g = gravity
24 bar stools refers to which US length measurement?
This refers to the measurement of a standard bar stool which is 24 inches. Therefore it is talking about the measurement inches and about the typical bar stool length.
A pendulum consists of an object of mass 1.21kg tht hangs at the end of a massless bar a distance 1.28m from the pivot point calculate the magnitude of the torque due to gravity about the pivot point?
The torque is the component of the weight that is perpendicular to the bar. So when the bar hangs vertically down, parallel to the force of gravity, there is no torque. If the bar makes an angle "A" with the vertical then the component of weight perpendicular to the bar would be mgSin(A) and the torque would be mgLSin(A) , where m= 1.21 kg, and L = 1.28m, g=9.8m/ss , so all you need is the angle "A".

What effect would the temperature have on the time kept by a pendulum clock made of iron bar?
I think you're saying that the pendulum itself is an iron bar.-- The period of the swing is determined by the pendulum's length. Whether the pendulumis a long distributed mass, or just all one lump down at the end, its effective length ineither case is the distance from the pivot to its center of mass.-- Rising temperature makes the iron bar longer, but doesn't change its mass. So itscenter of mass becomes farther from the pivot, and its period of swing increases.-- So higher temperature would make the clock run slower.This sounds like an elegant way to detect small differences in local gravity at differentplaces. I don't know for a fact, but I'll just bet that this is how it's actually done, witha portable instrument based on a pendulum-regulated timekeeping device.
Is a bar code a ratio level of measurement?
No, it is nominal.
Is 20mm diameter bar has a grade of 8.8?
8.8 is a quality measurement, 20 mm is a size measurement. They're not dependent on each other. You can have a 20 mm bar in any quality, as you can have an 8.8 quality bar in any size.
Which graph shows a single measurement of a number of object?
BAR
