Physics - ICS Part 1 Physics Chapter 1 Short Questions Test

Question # 1

What are derived units? Explain.

Ans 1: The units associated with the derived quantities are called derived units. SI units for measuring all other physical quantities are derived from the base and supplementary units. For example , newton, joule,watt and pascal are derived units.

Question # 1

What is importance of bivalent formation?.

Ans 1: Due to bivalent formation of homologous chromosomes,the non sister chromatids exchange their segment during the crossing over resulting in new recombination.

Question # 1

Explain the term " precision" and accuracy ?

Ans 1: The 'Precision represents the magnitude of error in a measurement while the accuracy means to check how the measured values are closer to the actual value. The accuracy represents the relative error. It can be obtained by dividing the error with measured quantity.
The accuracy depends on the error if the error is greater than smaller will be the accuracy of the measurements and vice versa.
The accuracy of the measurements can be increased by taking several readings and take their average.

Question # 1

Define prefixes and write two examples.

Ans 1: Prefixes: Prefixes are the words or letters added before a unit and stand for the multiples or sub-multiples of that unit
Ans 2: Examples: Kilo (k) mega (m), micro (m), milli (m) etc.

Question # 1

Write the main type of error.

Ans 1: There are two types of errors possible I n physical measurements.
1. Random error
2. Systematic error

Question # 1

Define systematic errors. Explain how can we remove the effect of systematic errors?

Ans 1: Systematic Errors: Systematic errors occurs when repeated measurements of a quantity give the same values under the same conditions.
This error is due to poor calibration or zero error in the stop watch. This error can be removed by applying correction factor.

Question # 1

what is time period?

Ans 1: The time taken by vibrating body to complete its one vibration is called time period.

Question # 10

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
