Question # 1

What is meant by coexistances.

Ans 1: Living with other human beigns in peace and harmony mutual peace and lvoe is claled coexistence

Question # 4

What do you mean by significant figures ? Give the rules for determining significant figures ?

Ans 1: Significant Figures:The combination of accurately known digits and the first doubtful digits during a measurement are known as as significant figures
Rules for determining significant figures:
1. All non-zero digits from '1' to '9' are significant for example in 36.473 m there are five significant figure
2. All zero between two non-zero digits are significant for example in y= 4.03 m there are three significant figures
3. The zero to the right of a decimal symbol and to the left of non-zero digits are not significant
4. All zero to the right of a decimal appears after non-zero digits are significant
5. In case of scientific notation the figures before the power of ten are significant
6. In case of addition and subtraction the result obtained is retained to the measurement which is least precise in the data
7. In case of multiplication and division the final result is retained to the measurement which contains the last number of significant figure
8. In case of rounding of non-significant figures the following rules should be followed.
- IF the dropping digits is less than '5' then it will be just ignored For example 863.73 is rounded to 863.7
- If the dropping digits is greater than '5' then the last retained digit is increased by '1' for example 8.76 is rounded of 8.8
- If the dropping digits is '5' and the last retained digits is even then it will remains uneffected. for example, 56.45 is rounded to 56.4
- If the dropping digits is '5' and the last retained and the last retained digits is add than it will be increased by '1' for example 46.35 is rounded to 46.4

Question # 6

What is physics ? Discuss the importance of physics ?

Ans 1: Physics:
The branch of science which deals with the properties of matter energy and their mutual relationship is known as physics.
Physics has played on importance role in our daily life.

5. X-rays, Y-rays Laser rays etc. are the inventions of physics which can be used in industry, health and agriculture department for various purposes.
6. Cathode ray oscilloscope (C.R.O) is the invention of physics which can be used as graph plotting device to see the wave from of a repetitive electronic signals the C.R.O can be also used in T.V circuits in computers system and as A.C circuits or D.C circuits circuits.
7. All means of transport, like aeroplane buses, motor cycles, railways etc work on the principles of physics
8. Electricity is the invention of physics without which we can not imagine any machine in working conditions
9. Rockets and satellites are the invention of physics with the help of which we can get information about the upper atmosphere.
10. The simple machine like pulley, wedge, like leaver screw-jack etc are the invention of physics which can be used for various purposes invention of physics which can be used for various purpose in daily life.
11. Physics explain the natural phenomena in term of fundamental principles and basics and basic Laws
12. Electron microscope is the invention of physics which is used to see distant objects clearly.
13. Microphone is the invention of physics which can be used to study microorganisms clearly and easily
14. Telescope is the invention of physics which is used to see distance objects clearly.
15. Physics employs the essential steps of scientific method observation recording analysis prediction and verification.

Question # 1

What is Scientific Notation .Explain ?

Ans 1: Writting number in power of ten or standard from N=M*10ⁿis called scientific Notation.
Explanation:With the help of Scientific Notation, we can express very large number or small number very easily. A large or small number "N" can be expressed in term of a number "M" and a power of '10 '
N= M * 10ⁿ-------------------(1)
In equation 1 "M" represents a number whose first digit is non-zero digit. "n" represents the power of 10, which may be positive or negative
For example 150,000,000,000 m can be expressed in scientific notation as under
150,000,000,000 m = 1.5* 10¹¹m
