I believe it is speed.
Hope this helps!
Answer:
14.49 g/cm²
Explanation:
I = Io e^-(ux)
Where:
I = 573
Io = 1045
x = 0.3 inches and
rho = 11.4g/cm^3
Using the conversion constant
1 inch = 2.54 cm;
0.3 inches = 0.3 * 2.54 cm
0.3 inches = 0.762 cm
I/Io = e^-(ux), or say
Io/I = e^(ux), taking the In of both sides
ln(Io/I) = ux, making u subject of formula
u = 1/x * ln(Io/I)
u = 1/0.762 * ln(1045/573)
u = 1.312 * 0.6
u = 0.787
Next, we say that
u/rho = 0.7872/11.4 = 0.069
And finally, we make
1/(u/rho) to be our final answer
Inverse of the answer is = 14.49 g/cm²
Therefore, the um^-1 in g/cm^2? is 14.49
Velocity = Distance / time taken
= 110 m /72s
1.52 ms⁻¹
Answer: 1. Being able to carbon date fossils
From the daily exposure to radioisotopes of organisms, scientists discovered to carbon date fossils. In carbon dating, the age of organic matter can be determined from the relative proportions of C-12 and C-14 i.e. isotopes of Carbon (carbon 12 and carbon 14). This ratio changes over the years because carbon-14 decays and is not replenished as there is no exchange with the atmosphere.
