SOMEONE PLSSS HELPP ME In a laboratory, you produce a quantity of the radioactive isotope unobtainium-253. Over the course of several weeks, the unstable isotope decays, and you measure the amount of unobtainium-253 remaining in the sample. You obtain the following data:
The half-life of unobtainium-253 is _Incorrect. days.

After 2 half-lives, there will be _Incorrect. grams of unobtainium-253 remaining in this sample.

After _Incorrect. days, there will be 1.5 grams of unobtainium-253 remaining in this sample.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
