(b)
Answer to Problem 1P
The order of neutron in human body is
Explanation of Solution
A human body is mostly composed of water. In water molecule there are
Thus the order of neutron in human body is
Conclusion:
The order of neutron in human body is
(c)
The order of magnitude of number of electrons in human body.
(c)
Answer to Problem 1P
The order of electrons in human body is
Explanation of Solution
A human body is mostly composed of water. In water molecule the number of protons and electrons are exactly same. Thus the order of number of electrons will be same as the order of proton in human body.
The order of electrons in human body is
Conclusion:
The order of electrons in human body is

What will be the decay rate at the end of the next half-life?arrow_forward
- A radioactive material decomposes half of its amount per minute. If after 2 mins, 100% undecayed amount decomposes into half, at what time it is still 100% undecayed?arrow_forwardShow that, half-life is directly proportional to mean life.arrow_forwardThe mass of a neutron, mn=10^-27 kg is trapped inside a nucleus of a cubical box of size 10^-14m with impenetrable walls.
