Repeated trials
Yes. There is no system of measurement that is "perfect" in every way. We work hard to reduce error or uncertainty when we measure stuff, but we cannot eliminate it.
Reduce the friction . . .Apply lubricant to the surfaces in contact, or reduce the mutual pressure.Friction the reduce . . .The phrase has no physical significance.
how an information system can reduce uncertainty
No, sand does not reduce friction but increase friction.
To reduce Random and Systematic errors that may have occured during the experiment, by taking their average. This can get the most accurate value.
replicate
experiment
An increase in temperature will reduce the density, reduce the viscosity, reduce thermal conductivity, and increase the specific heat capacity. A decrease in temperature will have the opposite affect.
There are no following principles listed in the question.
Internal controls can help companies reduce errors, which can help them save money and protect their reputations. Employee training is an example of an internalcontrolthat can reduce errors.
how can eliminating medical abbreviations reduce errors
how to reduce the problem of random error and systematic error while doing an experiment
average result is the result when you do a few times of the same experiment and get a few result then you average it.
Weighing by difference can reduce, but not eliminate, systemic errors in an experiment because systemic errors do not arise simply from errors in measurement, but from a variety of sources. Weighing by differences is still advised whenever possible.
