Bifocals: A bifocal lens is created with two different areas of vision correction, which are divided by a distinct line that sits horizontally across the lens. The top portion of the lens is used for distance, while the bottom portion of the lens is used for closer vision.

Vvijay Narra 5 years, 3 months ago

Bifocals are eyeglasses with two distinct optical powers. Bifocals are commonly prescribed to people with presbyopia who also require a correction for myopia, hyperopia, and/or astigmatism.

In parallel

Sayed Kaif 5 years, 3 months ago

Thank you so much

Yogita Ingle 5 years, 3 months ago

The arrangement of the system should be in parallel.
We can prove it with the help of formula
1/R= 1/R1 + 1/R2
1/R = 1/2 +1/2
1/R = 1
R= 1 Ohm

  • 2 answers

Yogita Ingle 5 years, 3 months ago

R1 = R2 = R3 = 3 Ω

1/R = 1/R1 + 1/R2 + 1/R3

= 1/3 + 1/3 + 1/3 = 3/3 = 1

∴ R = 1 Ω

The bonds which are formed by mutual sharing,pairing of electrons are covalent bonds

Yogita Ingle 5 years, 3 months ago

The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond. The molecules formed as a result of sharing of electron between two atoms are called as covalent molecules

According to the law of combination of resistance in parallel, the reciprocal of the combined resistance of a number of resistances connected in parallel is equal to the sum of the reciprocals of all the individual resistances.

5 resistance

Sumit Sharma 5 years, 3 months ago

First tell how many Resistances here

Gaurav Seth 5 years, 3 months ago

If five resistances are connected in series and all are of 0.2 ohm then their resistances would be added.

As per the law of combination of resistances in series,

R = R+  R+  R+ R+ R5

R = 0.2 + 0.2 + 0.2 + 0.2 + 0.2 = 1ohm

We have,

2x + 3y = 11 ….(1)

2x – 4y = – 24 ….(2)

From (1), we have 2x = 11 – 3y

Substituting 2x = 11 – 3y in (2), we get

11 – 3y – 4y = –24

⇒ –7y = – 24 – 11

⇒ –7y = – 35

⇒ y = 5

Putting y = 5 in (1), we get

2x + 3 × 5 = 11

2x = 11 – 15

⇒ x = –4/2 = – 2

Hence, x = – 2 and y = 5

Again putting x = – 2 and y = 5 in y = mx + 3, we get

5x = m(–2) + 3

⇒ –2m = 5 – 3

⇒ m = – 1

If five resistances each of value 0.2 ohm are connected in series what will be the resultant resistance

Gaurav Seth 5 years, 3 months ago

According to the law of combination of resistances in series, the combined resistance of any number of resistances connected in series is equal to the sum of the individual resistances.

The ghazal form is ancient, tracing its origins to 7th-century Arabic poetry. The ghazal spread into South Asia in the 12th century due to the influence of Sufi mystics and the courts of the new Islamic Sultanate, and is now most prominently a form of poetry of many languages of the Indian subcontinent and Turkey.[3]

Carbon has four electron in its valence shell orbital. So, it can neither accept nor gain four electron. One way to complete octet is by sharing of electrons. So, carbon forms covalent bond to complete its octet.

Valency of phosphorus is 3

Gaurav Seth 5 years, 3 months ago

Phosphorus has valency 3.

The valence (or valency) of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.
In PH3​,  P is combined to 3 H atoms, so the valency of phosphorous is +3.

Yogita Ingle 5 years, 3 months ago

The number of valence electrons or the number of electrons in the outermost shell of phosphorus is 3. - Thus, one atom of phosphorus is capable of combining with three atoms of hydrogen in order to form phosphine (PH3). Therefore, the valency of phosphorus in PH3 is +3.

Three examples to show the contribution of culture to the growth of nationalism in Europe were:

  •  Romanticism was a European cultural movement aimed at developing national unity by creating a sense of shared heritage and common history. The Romantic artists' emphasis on emotions, intuition and mystical feelings gave shape and expression to nationalist sentiments. The strength of art in promoting nationalism is well exemplified in the role played by European poets and artists in mobilising public opinion to support the Greeks in their struggle to establish their national identity.
  •  Folk songs, dances and poetry contributed to popularising the spirit of nationalism and patriotic fervour in Europe. Collecting and recording the different forms of folk culture was important for building a national consciousness. Being a part of the lives of the common people, folk culture enabled nationalists to carry the message of nationalism to a large and diverse audience. The Polish composer Karol Kurpinski celebrated and popularised the Polish nationalist struggle through his operas and music, turning folk dances like the polonaise and mazurka into nationalist symbols.
  • Language also played a distinctive role in developing nationalist feelings in Europe. An example of this is how during Russian occupation, the use of Polish came to be seen as a symbol of struggle against Russian dominance. During this period, Polish language was forced out of schools and Russian language was imposed everywhere. Following the defeat of an armed rebellion against Russian rule in 1831, many members of the clergy in Poland began using language as a weapon of national resistance. They did so by refusing to preach in Russian, and by using Polish for Church gatherings and religious instruction. The emphasis on the use of vernacular language, the language of the masses, helped spread the message of national unity.
