Question # 1

Give two example of phylum platyhelminthes and Nematoda.

Ans 1: Phylum platyhelminthes includes Liver fluke and Planaria.

Question # 3

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

Define Physical Quantities ? Explain base quantities and derived quantities?

Ans 1: Physical Quantities:All the measurable quantities are known as physical quantities for example, speed, mass , force, velocity, momentum temperature etc
- Base Quantities:These are those physical quantities in term of which other physical quantities can be defined the base quantities can not be defined in term of other physical quantities.
Example of base quantities:These are the seven base quantities, which are given below.
1. Mass
2. Length
3. Time
4. Current
5. Temperature
6. Amount of substance
7. Luminous intensity
- Derived Quantities:Those physical quantities which can be derived from base quantities are known as derived quantities

Question # 1

Define system of units ? Give the name of various system of unit?

Ans 1: System Units:A complete set of unit for all physical quantities is known as system of units .
Explanation:There are several system of unit For example
Foot - pound - system ( FPS)
Meter - kilogram -second system (MKS )
Centimetre - gram - second system (CGS )
But the most popular system id the system international (SI)
System International(SI):In 1960 on international committee agreed on a set of definitions and standards to describe the physical quantities. The system that was established is called system international (SI)
The system international is used throughout the world. Its unit are convenient for daily use .
The system international is build-up from three kinds of unit
- Base Unit
- Derived Units
- Supplementary Units

Question # 1

Define Base, Derived, supplementary, Units ?

Ans 1: Base Units:The units of base quantities are known as base unit.
Base quantity: Symbol
Length l
Mass M
Time t
Electric current I
Temperature T
Derived Quantity:The unit of derived quantities are known as derived units. The derived units can be derived from base unit and supplementary units
Supplementary Units:The general conference on weight and measures has not yet classified certain units of the SI under either base units or derived units such SI Units are called supplementary units This class contains only two units of purely geometrical quantities which are place angle and the said angle.
1. Radian :It is the unit of plane angle. One radian represents a plane angle subtended at the center of a circle by on are of length equal to radius of the circle.
2. Steradian:Steradian is the unit for a solid angle in a three dimensional space steradian is defined as "the solid angle subtended at the center of a sphere by an area of its surface equal to the square of the radius of that sphere"

Question # 1

Differentiate between the precision and accuracy.

Ans 1: Precision: A measurement which has less absolute uncertainty is called precise measurement. The precision of a measurement is determined by the instrument being used.Absolute uncertainty , in effect, is equal to the least count of measuring instrument.
Accuracy: is the one which has less fractional or percentage error. Accuracy measures,how close a measured value is to the actual value.
