ICS Part 2 Physics Chapter 21 Short Questions Preparation

Question # 1

Write down two advantages of solid state detector over geiger muller counter.

Ans 1: Solid state detector can count very fast than gas filled detector.
Solid state detector is much smaller in size.
It operates at low voltage.

Question # 2

If nucleus has a life of one year,does this mean that it will be completely decayed after two years?

Ans 1: No it will not decay completely after two years.
Numbers of atom at initial stage =N_o
number of atoms decayed after first year =1/2N_o

Question # 3

What are the relation between decay constantλand the half-line of a radioactive element?

Ans 1: The relation between decay constantλand the half line (T_1/2) isλT_1/2=0.693

Question # 4

A particle which produce more ionization ,is less penetrating.Why?

Ans 1: A particle with great power loses large amount of energy for small distances.That is,it produces more ionization but is less penetration.

Question # 5

What is half line?

Ans 1: The half line T_1/2of a radioactive elements is that period in which half of the atoms decay.

Question # 6

Describe the principle of operation of solid state detector.

Ans 1: The principle of operation of solid state detector is based upon the production of electron-hole pair to cause a pulse of current.

Question # 7

What is radioactivity decay?Give an example.

Ans 1: The emission of radiations from elements having charge number Z greater than 82 is called radioactivity or radioactive decay.
The emission of an a-particle from radium-226 ,result in the formation of radon gas.

Question # 8

What are isotopes?What do they have common and what are their difference.

Ans 1: Isotopes are such nuclei of an element that have the same charge number Z but have different mass number A.It means,in the nucleus the number of protons is the same but the number of neutrons is different.

Question # 9

How energy released when 1 amu converted into energy?

Ans 1: 1 amu= 1.66 x10^-27kg

the energy of 1 amu is 1 amu =1.494 x10^-10J
1 amu= 931 MeV

Question # 10

Discuss the advantage and disadvantage of nuclear power compare to the use of fossil fuel generated power.

Ans 1: Advantage and disadvantage of nuclear power are given below compared to the use of fossil generated power.
Advantage:
1. Much more energy is produced.
2. Produces no environmental pollution.
3. Electricity produced in this way is far cheaper than fossil fuel generated power.
Disadvantage :
1. Uranium mining is more dangerous than coal mining.
2. Nuclear waster is very injurous and harmful to living things.
3. Nuclear waste can not be transported through area of population whereas fossil fuel can be.
