Use v=voe^-t/rc and t=rc to derive t1/2=tln2

Enclosed is some guidance algebra.I find this q a little confusing. It quotes "RC" which usually makes me think of electrical circuits and time constants based on converting calculating RC value and equating that to t for one time constant then 2RC for two time constants etc. The theory being that after 5 time constants - 5RC - a circuit is stable. BUT, this q then goes on to mention HALF LIFE. The curves for both half life and time constant are both exponential, as in the number e to the power of something, but the algebra is slightly different. I hope my algebra is ok.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

[tex]First to answer will be the brainliest[/tex]

a very small rock.

but seriously, i'm assuming that this question has to do with density of a rock. if you have a chart with rocks and their corresponding densities would be best. the density of an object can be calculated by using the following formula:

[tex]density = \frac{mass}{volume}=\frac{2.7g}{1.1cm^3}= 2.45g/cm^3[/tex]

according to a chart i found that may be corresponding to a rhyolite rock since rhyolite rocks have a median density of 2.49g/cm^3 which is close to 2.45g/cm^3.

hope that !
