Scientific Notation

What is a measurement in the context of science?

• A quantity that has both a number and a unit

• A quantity that has only a unit

• A quantity that is estimated

• A quantity that has only a number

What is the range of the coefficient in scientific notation?

• Greater than 10

• Greater than 1 and less than 10

• Greater than 0 and less than 1

• Less than 0

How do you determine the exponent in scientific notation for a number greater than 1?

• Count the number of zeros

• Count the places moved to the left

• Count the number of non-zero digits

• Count the places moved to the right

What does a negative exponent in scientific notation indicate?

• A positive number

• A negative number

• A number greater than 1

• A number less than 1

What is the difference between accuracy and precision?

• Accuracy and precision are the same.

• Neither accuracy nor precision is important in measurements.

• Accuracy is about consistency, while precision is about being close to a known value.

• Accuracy is about being close to a known value, while precision is about consistency.

What does percent error measure?

• The total error in a set of measurements

• The ratio of error to actual value, expressed as a percentage

• The difference between experimental and actual values

• The consistency of measurements

Which zeros are considered significant in significant figures?

• Trailing zeros without a decimal point

• Leading zeros

• All zeros are significant

• Zeros between non-zero digits

How are significant figures used in calculations?

• To round all numbers to the nearest whole number

• To ensure data is not reported more precisely than measured

• To report more data than measured

• To increase the precision of the calculation

In the context of significant figures, what does the term 'infinite' imply?

• The measurement was not taken accurately

• The number of significant figures is unlimited

• There are no significant figures

• The number of significant figures cannot be determined

What is the significance of the decimal point in determining significant figures?

• It has no impact on significant figures

• It signifies the end of significant figures

• It indicates that all zeros to the right are significant

• It only affects the first digit to the right
