Question

Help please!!!!!

Which of the following is an example of systematic error?

A scientist misreads a ruler when measuring the length of an insect.

A rainstorm washes away soil in a plot of land where a scientist is testing the effect of a new fertilizer on grass.

A scientist measures the mass of a rock on an older scale that is imprecise.

A scientist spills a foreign chemical into a reaction vessel, changing the reaction.

Answer 1

`Systematic error in physical sciences commonly occurs with the measuring instrument having a zero error. A zero error is when the initial value shown by the measuring instrument is a non-zero value when it should be zero.`

With this I would believe that It would be C....this is because the scale is imprecise so you would need to make calculation in order to find the true value.
