Question # 1

What dose the word "micro" signify in the words "micro wave oven ?

Ans 1: Micro means very small. Micro waves have the shortest wavelength of all the shortest wavelengths of all the radio waves, therefore, these are known as microwaves. Now like all electromagnetic waves the microwaves produces heating effect when their energy is absorbed. It is because, due to shorter wave length the micro waves posses high frequency and maximum energy.

Question # 1

How can we reduce random and systematic error?

Ans 1: Reduce random error: Repeating the measurement several times and taking an average can reduce the effect of random error.

Reduce systematic error: The systematic error can be reduced by comparing the instrument with another which is known to be more accurate and a correction factor is applied.

Question # 1

Why a screw gauge measures more accurately than a vernier cllipers

Ans 1: Because least count of screw guage is 0.01mm and divide 1mm into 10 equal parts. But least count of vernier calipers is 0.1mm and 1mm. divide into 10 equal parts.

Question # 1

Explain " Rounding off numbers ?

Ans 1: The quantities in a measurement are always rounded off to certain level of accuracy. The following rules must be observed while rounding off a number.
1. If the dropping digits is less than "5" then the last retained digit is kept as it is For example 863.73 is rounded to 863.7
2. If the dropping digits is greater than '5' then the last retained digits is increased by '1' for example 9.66 is rounded to 9.7
3. If the dropping digits is '5' and the last retained digit is even then it will be remain uneffected. For example 66.45 is rounded to 66.4
4. If the dropping is '5' and the last retained digit is add, then it will be increases by '1' for example 76.35 is rounded to 76.4

Physics has played on importance role in our daily life.
1. The electronic media like T.V, radio, Loudspeaker, Telephone, cell phone, Photo phone for machine etc are the important source of communication which works on the principles of physics.
2. Information technology is based on the principle of physics which is the scientific method of storing, protecting, processing, Transmitting, receiving and retrieving information
3. The whole world has become a global village due to use of computer net works which works on the principles of physics.
4. Atomic bomb is the invention of physics which can be used for the production of huge amount of energy. It can be also used for defence purposes.
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.
