A patient was injected with Tc-99m 12 hrs ago to complete a bone scan and 3.0 mCi remains in her blood stream. If the half life of Tc-99m is 6 hrs. How much Tc-99m was she injected with?

i think   the answer is c hope i'm right

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
