define surface tension at angle of contact​

Explanation:

The finite automata or finite state machine is an abstract machine which have five elements or tuple. It has a set of states and rules for moving from one state to another but it depends upon the applied input symbol. Basically it is an abstract model pf digital computer. Following figure shows some essential features of a general automation.

It is a powerful model which was proposed by Alan Turing in 1936. The earlier models like finite automata and push-down automata are bot considered as the accurate models because they cannot recognize simple language. But the turing machine is the most accurate model for the personal computers. A turing machine is capable of solving every problem that a real computer can do. There are also some problems which can not be solved by turing machine because these problems are beyond the theoretical limits of computation.

Finite Automata Turing Machine

It recognize the language called regular language. It will recognize not only regular language but also context free language, context sensitive language and recursively enumerable languages.

In this the input tape is of finite length from both left and right side. In this the input tape is of finite length from left but is of infinite length from right.

It consists of finite number of states, finite set of input symbols, initial state of automata and finite set of transition rules for moving from one state to another. It also contains finite set of tape symbols and a blank symbol on the tape in addition to finite number of states, finite set of input symbols, initial state of automata and finite set of transition rules for moving from one state to another.

In this head is able to move in right direction only. In two way automata, head is able to move in both directions. In this, head can move in both directions.

Head is only able to read the symbols from the tape but can not write symbols on the tape. Head is able to read as well as write symbols on the tape.

It is weak as compare to Turing Machine. It is powerful than Finite Automata.

Designing finite automata is easier. Designing turing machine is difficult and as well as complex.

The transition function in finite automata can be represented by :

δ : Q × Σ* → Q The transition function in turing machine can be represented by :

δ : Q × T → Q × T × {L, R}

where L and R specifies the left and right movement of tape head.

Answer:

O is the centre of the circle.

CD is the diameter, CD = 5 cm

EF is the chord parallel to CD, EF = 3 cm

OG is perpendicular drawn on EF from O.

In ΔOGE we have,

∠OGE = 90° [∵ OG is perpendicular on EF]

OE = 5/2 = 2.5 cm [∵ Diameter = 5 cm]

EG = 3/2 = 1.5 cm [∵perpendicular drawn from centre bisects chord]

∴ Area of the quadrilateral,

= 8 cm2

The answers are Radius of circle 5 cm

               Area of Quadrilateral  = 20 cm²

Given: Bottom side of the quadrilateral is diameter of the circle

From given picture bottom of the quadrilateral AB = 10cm

and CD = 6 cm

To find: Radius of the circle and area of the quadrilateral

Solution:

a) Radius of circle

given that diameter of circle = bottom of quadrilateral  

⇒ diameter of circle 2r = 10 cm

⇒ Radius of circle r = 10/2 = 5 cm

∴ Radius of circle 5 cm

b) Area of the quadrilateral

Draw a line by joining mid points of AB and CD

and join mid point of AB and vertice C then a right angle triangle POC  is formed as show figure

In triangle POC  ⇒  OC² = OP²+ PC²  

[ here OC = radius = 5 cm and PC = [tex]\frac{1}{2} (CD)[/tex] = 3 cm ]

⇒  5 ² = OP²+ 3²  

⇒ OP² = 5² - 3² = 25 - 9 = 16

⇒ OP² = 4²

⇒ OP = 4  is the altitude/height of trapezium

Therefore, area of trapezium =  [tex]\frac{1}{2} (base)(height)[/tex]  

⇒ [tex]\frac{1}{2} (10)(4)[/tex] = 5(4) = 20 cm²

∴ Area of triangle = 20 cm²

My Christmas Holidays:

On my Christmas Holidays I didn’t have any day I didn’t make anything.

On 25th December I went to my grandpa and my grandma’s house to have the Christmas lunch. In the afternoon I went to see “Pastorets”, and in the evening I stayed in my home with my family and we watched the TV.

On 26th December I went to my other grandma’s house for having another Christmas lunch. And in the afetrnoon I went to see “Pastorets again.

In 31st December I went to campelles with my cousin and my aunt, and two other families and we slept two nights in a hotel. In the night we ate the grapes at 00:00, we laughed a lot and we had fun.

In the morning of 5th Jenuary I went to visit the “pageboys” of the kings and in the evening I went with my little cousin to give the letter to the kings of “Orient”.

And on 6th I opened the presents in my house and at my grandmpa’s house and we had lunch, and for dessert we ate the ring-shaped cake of the kings.

I had a very nice Christmas holidays… But there were very short!!!
