Indian Air Force Agniveer Science Subject Mock Test - 9 - Question 1

Which is the strongest fundamental force of nature?

Detailed Solution for Indian Air Force Agniveer Science Subject Mock Test - 9 - Question 1

Among all these 4 forces the Strong nuclear force also called strong nuclear interaction is the strongest one in comparison of the other three.

  • It is because it binds the fundamental particles of any matter together to form larger particles.
  • Fundamental particles mean protons and neutrons.
  • Quarks are made up of protons and neutrons and this strong nuclear force holds together the quarks.
  • The strong nuclear force also binds the proton and neutrons to the nucleus of the atom.
  • Also, a small strong force acts between protons and neutrons.
  • As protons repel each other due to having the same charges, the strong forces also keep them together.

This strong force will operate only when the subatomic particles are extremely close to each other, which is approximately 10-15.

So, like this, the strongest fundamental force is nature keeps nature balanced by keeping the matter in a stable form.

Additional Information: In nature, there are 4 fundamental forces. Every fundamental force plays vital importance to drive nature smoothly and knowingly or unknowingly we experience them in everyday life. A force is weak or strong which depends on the type of force it is having fundamentally.
The 4 fundamental forces are:
1. Gravitational force
2. The weak force or the weak nuclear force
3. Strong nuclear force or the strong nuclear interaction
4. Electromagnetic force

Indian Air Force Agniveer Science Subject Mock Test - 9 - Question 27

Direction: The sentences given in the question, when properly sequenced, form a coherent paragraph. Each sentence is labeled with a letter. Choose the most logical order of sentences from the given choices to construct a coherent paragraph.

A. With his iconic painting, Margritte showed how art can change our view of this world and give us a fresh opportunity to attempt to define the indefinable.

B. Magritte, who considered himself a thinker who communicated through paint, wanted to prove that images could equal words in the expression of consciousness.

C. In painting this, Margritte was inspired by the definition of a poem by popular literary figures André Breton and Paul Éluard, who declared that “Poetry is a pipe”.

D. One of René Magritte’s most famous paintings, “The Treachery of Images,” features an image of a tobacco pipe with the words “This is not a pipe” underneath it.

Detailed Solution for Indian Air Force Agniveer Science Subject Mock Test - 9 - Question 27

All four sentences given talk of the painter Magritte. Sentence D is the only one that states his full name: René Magritte. So, this is the starting sentence of the paragraph.

Sentence D describes the painting, "“The Treachery of Images". Now, both C and A refer to the painting: C states what inspired Margritte "in painting this", while A states what Margritte achieved with the help of his iconic painting. But clearly, the pronoun reference--this-- in C relates to the painting described in D. So, C follows immediately after D.

Now, Sentence B states what Magritte wanted to prove, whereas A states what he did prove with his painting. So, A follows B.

DCBA is the right order.

The question is " Arrange the sentences in the correct order "
The order is DCBA

Hence, the answer is DCBA
Choice D is the correct answer.

Indian Air Force Agniveer Science Subject Mock Test - 9 - Question 28

Direction: Read the passage and answer the questions that follow:

Paragraph 1: It is difficult to recognise the new generation of terrorists as a mere extension of the earlier lot of radical Islamist terrorists who were influenced by the teachings of Islamist preachers and theologians. There is less theology today and the new age terrorist seems to belong to an altogether different genre of terrorism.

Paragraph 2: A large number of terror attacks in the past three years have been attributed to the handiwork of the Islamic State (IS), and reveal its leaning towards the “nihilism” of Sayyid Qutb. It is this which distinguishes the IS from many of the other radical Islamist groups such as al-Qaeda and its affiliates. The IS’s recruitment techniques, especially its ability to proselytise over the Internet, including “direct to home jihad” as also its more sanguinary brand of violence, set it apart from earlier variants of radical Islamist terror.

Paragraph 3: Even while the IS has gained a great deal of prominence due to its brand of violence, other terror networks have continued to be no less active. For example, Al-Qaeda and its affiliates. Boko Haram in Africa has been responsible for more killings than most people would realise. Closer home, the Afghan Taliban and the Haqqani network have carried out several spectacular attacks inside Afghanistan. The Tehrik-e-Taliban Pakistan (TTP) and the Lashkar-e-Jhangvi have carried out several attacks inside Pakistan. Pakistan provides the wherewithal and the support to terror outfits such as the Lashkar-e-Taiba and the Jaish-e-Mohammad to launch well-planned attacks on Indian targets.

Paragraph 4: Most of these outfits continue to adopt earlier methodologies. These have proved no less effective than those followed by the IS. The terror attack on a mosque in North Sinai, Egypt in November this year, which killed over 230 persons, is one such example. In December, the TTP was responsible for a terror attack on an agricultural training institute in Peshawar, Pakistan. Differences among terror outfits do not, however, preclude a complicated pattern of relationships when it comes to operational aspects.

Q. As per paragraph 4, which of the following is true with respect to earlier methodologies adopted by terror outfits?

I. Such methods are no longer followed.
II. Such methods are as effective as the newer ones.
III. Such methods are followed by upcoming groups in various countries
