D- if i was right please mark me as a brainliest answer and a thank you
Displacement will be 15 too because
It falls from 0 till 15 meters
That would be Italian dressing because it does not mix completely therefore it is the definition of a heterogeneous mixture
6.35x10^-4 OR 6.3x10-4 (if only one decimal number is allowed)
Answer:
8.61 min
Explanation:
original mass= 12.65
first half life = 12.65/2 = 6.325
second half life = 6.325/2 = 3.1625
Note : 3.1625 is the closest to the value (3.115) given so we work with it
total time for decay =17.22
therefore two decays = 17.22/2= 8.61
