Let ABCD be the given rhombus with diagonals AC and BD which intersect each other at O such that AC = 8 cm.

Since diagonals of a rhombus bisect each other, we get

Let BO = x and AB = 5 cm   (given).

We know that diagonals of a rhombus cut each other at right angles. So ΔAOB is a right angled triangle.

Using Pythagoras theorem in ΔAOB, we get

x = 3 cm

Thus the length of another diagonal BD is,

BD = 2x = 6 cm.

Therefore the area of the rhombus is given by,

Area of rhombus =

Area(ABCD) = 

                    = 

                    = 

Area of a rhombus is 24 .

8cm

Yogita Ingle 5 years ago (2577571)

<pre> Area of rhombus = ½ × d1× d2 ⇒ 16 = ½ × 4 × d2 So, d2= 32/4 = 8 cm</pre>

Let as assume that to the contrary ,that 2√5 is rational. 2√5 =a/b (a and b is coprime and integers and q is not equal to 0 ) √5=a/2b a and b are integers , a/2b is rational , and so √5 is rational . But this contradicts the fact that √5 is irrational . This contradiction has arisen becz of our assumption was wrong that 2√5 is rational. Hence 2√5 is irrational number.

Basant Kumar Mahto 5 years ago (9793686)

Let 2√5 be rational number.it can be written in the form of p/q. 2√5=p/q √5=p/q. 1/2 We know that √5 is irrational number. It has arisen our assumtion is worng that 2√5 is rational number. Hence 2√5 is irrational number.

Primary memory is the main memory of the computer system. Accessing data from primary memory is faster because it is an internal memory of the computer. The primary memory is most volatile which means data in primary memory does not exist if it is not saved when a power failure occurs.

The primary memory is a semiconductor memory. It is costlier compared with secondary memory. The capacity of primary memory is very much limited and is always smaller compares to secondary memory.

Two types of Primary Memory are:

  • RAM
  • ROM

All secondary storage devices which are capable of storing high volume data is referred to secondary memory. It's slower than primary memory. However, it can save a substantial amount of data, in the range of gigabytes to terabytes. This memory is also called backup storage or mass storage media.

Mass storage devices:

The magnetic disk provides cheap storage and is used for both small and large computer systems.

Two types of magnetic disks are:

  • Floppy disks
  • Hard disks

Flash/SSD

Solid State Drive provides a persistent flash memory. It's very fast compared to Hard Drives. Frequently found in Mobile phones, its rapidly being adopted in PC/Laptop/Mac.

Optical drives:

This secondary storage device is from which data is read and written with the help of lasers. Optical disks can hold data up to 185TB.

x-1/y=1/3 X/y+8=1/4 3x-3=y 4x=y+8(substitute value of y) 4x-3x=-3+8 X=5

Yogita Ingle 5 years ago (2577571)

Let us assume thenumerator to be =x

Let us assume thedenominator to be =y

Hence the fractionbecomes=x/y

Accordingtothe given condition

(x−1)/y=1/3

⇒y=3x−3 ———-(i)

Accordingtothesecond givencondition,

x/(y+8)=1/4

⇒y+8=4x

⇒y=4x−8 ————(ii)

Combining(i)and(ii) we get,

3x−3=4x−8

⇒3x−4x=−8+3

−x=−5

⇒x=5

from(i)

y=15−3=12

So,the fraction is =5/12

✳Stratified squamous ✳Columnar ✳ Cuboidal

Swetha Komaragiri 5 years ago (9801673)

Epithelial tissues are identified by both the number of layers and the shape of the cells in the upper layers. There are eight basic types of epithelium: six of them are identified based on both the number of cells and their shape; two of them are named by the type of cell (squamous) found in them.

Yogita Ingle 5 years ago (2577571)

SIMPLE

  • The cells are extremely thin and flat and form a delicate lining.
  • The lining of oesophagus and the mouth are covered with squamous epithelium.

STRATIFIED

  • The cells are arranged in many layers to prevent wear and tear.
  • Since they are arranged in a pattern of layers, the epithelium is called stratified squamous
  • The skin, which protects the body, is made of squamous epithelium.

COLUMNAR

  • The columnar (meaning ‘pillar-like’) epithelium facilitates movement across the epithelial barrier.
  • It is present where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present.
  • In the respiratory tract, the columnar epithelial tissue also has cilia, which are hair-like projections on the outer surfaces of epithelial cells.
  • These cilia can move, and their movement pushes the mucus forward to clear it. This type of epithelium is thus ciliated columnar epithelium.

CUBOIDAL

  • Cuboidal epithelium (with cube-shaped cells) forms the lining of kidney tubules and ducts of salivary glands, where it provides mechanical support.
  • Epithelial cells often acquire additional specialisation as gland cells, which can secrete substances at the epithelial surface.
  • Sometimes a portion of the epithelial tissue folds inward and a multicellular gland is formed.

The cyclic process of nitrogen fixed, and used by plants & animals & later returned to the atmosphere, is referred as nitrogen cycle.

Yogita Ingle 5 years ago (2577571)

Nitrogen cycle is all about the movement of nitrogen between various elements on Earth (like air, soil, living organisms etc.) The amount of nitrogen in the atmosphere remains constant.

  • Atmosphere has approx. 78% nitrogen.
  • Atmospheric Nitrogen is fixed into the soil
    • N2 fixing microbes convert atm. N2 into nitrogen compounds like NH3
  • Plants utilize nitrogen from soil through their roots
  • Animals utilize nitrogen, feeding on plants
  • When Plants & animals die, Nitrogenous wastes are returned to soil
    • Decomposers convert some part to nitrogen compounds to be used by plants
    • Denitrifying bacteria convert into atm. N2

The nitrogen cycle is the biological cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

Saumya Kumar 5 years ago (8891027)
