Cooking energy to our cars liquid fuels
Answer:
The loaded ship will weigh more. Thus it will sink down farther in the water in order to displace that much more water so that it continues to float.
Radioactive elements obey 1st order kinetics,
For 1st order reaction, relation between rate constant (k) and half life [t(1/2)] is,
k =
Also, for 1st order reaction, we have
t =
Given that: <span>the bones from a mastodon had lost 78.5% of their C14,
</span>∴ initial conc. of C14 = 100%, conc. of C14 left after time 't' = 21.5%
∴t =
= 1.2758 X 10^4 hours
