Idk but it is probably fast
The answer would be C. Amplitude
If you have 200. 0 g of radioisotope with a half-life of 5 days. 25g of isotope would remain after 15 days
Isotopes are members of an element family that have the same number of protons but differ in the number of neutrons. The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus. Carbon, for example, has six protons and has atomic number 6.
Radioisotopes are elemental radioactive isotopes. They can alternatively be defined as atoms with an unstable neutron-proton combination or surplus energy in their nucleus.
Radioisotopes are critical components of medical diagnostic techniques. They can be utilized for imaging to examine the dynamic processes taking place in various sections of the body when combined with imaging devices that register the gamma rays emitted from within.

Explanation:
The given data is as follows.
Water flux,
= 25 
= 
So, let velocity (u) =
m/s = 
= 998 
Pore size, d = 
= 0.9 cP =
Pa.s
Hence, calculate the reynold number as follows.
=
= 
= 0.006
This means that the flow is laminar.
Now, we use Hagen-Poiseuille equation as follows.

where,
= membrane porosity = 0.35
d =
m
= 
= 
= tortuosity
= membrane thickness = 

= 3.73
Hence, the tortuosity factor of the pores is 3.73.
As flow resistance = 

Water permeability is represented by
.
=

Therefore, the resistance to flow is
and its water permeability is
.
The right answer for the question that is being asked and shown above is that: "b. positive or negative charge" An isotope undergoes radioactive decay by emitting radiation that has no mass. The other characteristic does the radiation have is that b. positive or negative charge
