True or False: Random errors primarily affect the accuracy of a measurement, while systematic errors primarily affect the precision.

True or False: Scientific evidence is distinct from other forms of evidence, such as historical documents or faith, because scientific evidence must be repeatable and open to experimental testing against measurement.

If a length measurement is recorded as $450\ \text{nm}$ (nanometers), what is this value expressed in meters using standard scientific notation?

If a physical quantity is measured as $0.000000007\ \text{m}$, which SI prefix would be most appropriate to express this value in a more readable format?

True or False: Systematic errors can be effectively reduced by repeating measurements and calculating a mean (average).
