On the contrary, if the parallax angle is too small, it can't be measured accurately.

Is it possible to have quadrilateral whose sum of angle measurement is less than 360 degrees?

No because the 4 interior angles of any 4 sided quadrilateral always add up to 360 degrees.

When going from larger to smaller units of measurement do you always divide?

No, never.

The standard error of measurement is always zero when the reliability coefficient equals what number?

.00

Why does universal indicator not always give an accurate result?

Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.

When is a measurment accurate?

Never: A measurement made is always an approximation. We can get very close to being accurate with our measurements, but never fully 100% accurate. This is not the fault of the person measuring, or what tool they are using to measure with, but it is a natural law that we (anyone, even superior aliens to humans) cannot ever fully make an absolutely accurate measurement.

Why should you avoid parallax?

There is no such way to avoid parallax error, you just have to be careful.. :)

Is less precise instrument always more accurate?

No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).

What is the best technique of using a graduated cylinder?

To accurately measure the volume of a liquid using a graduated cylinder, make sure to read the meniscus at eye level to avoid parallax error. Pour the liquid slowly and carefully to prevent spills and ensure an accurate measurement. Always use the smallest graduated cylinder that can hold the volume of liquid you are measuring for increased accuracy.

Is the unit of a number have importance in significant figures?

No, the units are independent of the accuracy. If you are measuring volume, how accurate the measurement is (or isn't) will not affect what you are measuring - it will always be volume.

What device must always be zeroed out before egin to use it before measurement?

A scale or balance should always be zeroed out before using it to ensure accurate measurements. This process removes any potential errors or biases that may affect the measurement results.

Why is the world difficult to predict?

Because its always changing and there are too many possible factors to make an accurate prediction.

What planet would have no advantage of any kind over earth for making parallax measurements?

You have to ask yourself what is an advantage when parallax measurements are being made? . . parallax happens when you move to a different place and the object you see look a little different, the closest ones appear to have moved more than the ones that are further away. In astronomy parallax is created when the Earth is in opposite points of its orbit. Stars that are close appear to have moved a little, relative to the mass of stars that are a long distance away. Parallax was not observed before the 19th century, and the lack of parallax was always used to 'prove' that the Earth could not possibly be going round the Sun. It was only in the 19th century that parallax was observed, but it was only very tiny movements of the closest stars. It forced people to realise that the stars are incredibly far away and the Earth does go round the Sun after all, so it was extra evidence of the Sun being at the centre of the solar system. A parallax measurement is easier to make if the baseline is longer, so the answer to your question is that Mercury and Venus have no advantage for making parallax measurements.

What is a measurment closee to the true size?

Accuracy

Why is millimeters more accurate than centimeters?

Millimeters are more accurate than centimeters because they are smaller units of measurement, allowing for more precise measurements. Since there are 10 millimeters in a centimeter, using millimeters as the standard unit provides a more detailed measurement scale.

Why is significant figures important is measurement?

Significant figures are important in measurement because they indicate the precision of a measurement. They help communicate the reliability and accuracy of the measurement to others. By using the appropriate number of significant figures, we can avoid misinterpretations and errors in calculations.
