A student noticed that the average diameter of the glass beads used for the mass measurements was significantly smaller than those used for the volume measurements. How would experimental determination of the density of glass be affected? Is this a systematic or a random error?

The error mentioned is a systematic error.

Step-by-step explanation:

The glass beads used for mass measurements was noticed to be significantly smaller than those used for volume measurements.

The formula for density is = .

So if we try to experimentally determine the value of density of glass then the beads for measuring the mass are much smaller than the beads for measuring volume.Thus in this case we can see that the density measured will actually be less than the actual density of glass.

However since this error can be seen and quantified and corrected it is not a random error, but it is a systematic error.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
