The logic is:

Column 1: 9 × 5 × 3 = 135

Column 2: 5 × 7 × 4 = 140 

Similarly,

Let the missing number in column 3 be 'a'.

So, 5 × a × 5 = 150

⇒ 25 × a = 150

⇒ a = 150 ÷ 25

⇒ a = 6

Hence, ‘6’ is the correct answer.

Given Statement: P < Q < R < S = T

I. Q < T → True (As, Q < R < S = T → Thus, it is clear that Q < T. So, the conclusion is true)

II. P > S → False (As, P < Q < R < S → Thus, it is clear that P < S. So, the conclusion is false)

III. R = T → False (As, R < S = T → Thus, it is clear that R < T. So, the conclusion is false)

Hence, the correct answer is "Only conclusion I follows".

In the given figure, we can identify multiple triangles. By counting the individual triangles, we can determine that there are a total of 12 triangles in the figure.

Communicating information effectively by making use of appropriate technology is called Information and Communication Technology (ICT).

• It is an umbrella term that includes many communication devices such as radio, television, cellular phones, computers and network, satellite systems and so on.
• It is defined, as a “diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage information."

Important Points

Two objectives of ICT are:

• To establish smart schools
  • ICT allows schools to use advanced technology and equipment in classrooms to give students a better learning experience.
  • These schools use gadgets such as laptops, teaching screens, and projectors to add a visual effect to learning.
• To increase the capacity of teachers
  • The concept of capacity building in education includes various aspects ranging from training teachers, developing the digital contents, implementing basic ICT infrastructure (computers and networking) and putting in place well-designed local ICT policies.
  • It helps teachers to interact with students.
  • It helps them in preparing their teaching, provide feedback.

Thus, it is clear that the objective of ICT is to establish smart schools and to increase the capacity of teachers.

Additional Information

Advantages of using ICT in education: 

• It is of great use in achieving various objectives of the teaching-learning process.
• It provides correct information in a comprehensive manner with different examples.
• It helps learners to broaden their information base.
• It provides variety in the presentation of content, which helps learners to learn according to their own pace.
• It helps in better understanding and long retention of information.

ICT is a broad and inclusive phrase that encompasses both information and communication technology.

Key Points

• ICT has the potential to help teachers and students achieve a variety of goals in the learning process.
• ICT in education is the use of information and communication technology to assist, enhance, and optimise the transmission of information. 
• It has been found in studies ICT can increase student learning and teaching approaches.
• Teachers have long used multimedia as a teaching-learning tool because it provides the opportunities to listen, watch, and work in a computer-mediated environment.
• The use of sound, images, and video allows the viewer to experience real-world scenarios. 

Therefore, Video clippings are an ICT-enabled teaching aid. 

Additional Information

• The use of multimedia in teaching has become more popular in recent years.
• It has the potential to be engaging, interesting, and motivating, as well as assist students in achieving learning objectives in novel ways. 

Information and communication technology (ICT) refers to the use of electronic technology to send save, create, display, share or exchange information. Radio, television, video, DVD, satellite systems, computers, etc. are included in the ICT technologies.

• The tools of ICT are not a single technology but a combination of hardware, software, multimedia, and delivery systems. It may be in the form of audio, visual, and audio-visual. 

Key Point

Advantages of ICT Tools:

• Cost efficient - ICT tools are cost efficient as sending an email is cheaper than phone calls. ICT has also helped to automate business practices, thus restructuring businesses to make them exceptionally cost-effective. ICT tools make availability of free e-contents.
• ICT as Auido-Visual aid - A teacher can use ICT tools as teaching aids to stimulate the interest of students in learning. For example, a teacher who is going to introduce adjectives to class Ist students. He can use graphics, visual presentation, and audio-visual aids to make classroom learning interesting.
• Direct classroom learning: ICT tools are used in direct classroom learning as these tools shift the learning from solitary learning to learning with others. It makes learning more active in nature as there is direct interaction of the learner with ICT tools. It places the learner at the center and encourages collaborative learning in the classroom.

Hint

• Reliance on technology: Errors can be caused by over-reliance on and trust in technology’s proper function. Technology can occasionally malfunction, misdirect users, or give incorrect information or recommendations that result in users changing a previously correct decision or following a pathway that leads to error. Over-reliance on technology can result in serious consequences.

Hence, it is clear that reliance on technology is not an advantage of ICT tools.

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices.

Cooperation teaches the values of committing oneself to the common good, seeing success as depending on the efforts of all participants, feeling happy when others succeed, seeing others as resources to help one succeed, viewing worth as unconditional, and viewing diverse others in positive ways.
Cooperative learning is a teaching way for students to learn essential interpersonal life-skills and develop the ability to work collaboratively, a skill now greatly in demand in the workplace. Thus, it provides faster and efficient learning. In cooperative learning, the diverse students in the school are to be transformed into a symphony. Students need positive self-esteem, the psychological health to face conflict and challenge, and the social competencies required to work effectively with diverse peers. Personal and superordinate identities are developed through group processes.

Gravitational force between two objects is mathematically represented as:
F = G × (m₁×m₂) / r²
Applying the Law of Gravitation,
Given that the initial force F is due to two objects each of mass m separated by a distance r.
Substituting these into the formula gives:
F = G × (m×m) / r²
The problem then states that the mass of each of the objects is doubled (to 2m) and the distance between them is also doubled (to 2r).
The new force F' using these values in the formula would be: F' = G × (2m×2m) / (2r)²

Simplifying this gives:
F' = 4G × (m×m) / 4×r²
This simplifies further to:
F' = G × (m×m) / r²
Comparing this with the original equation for F, we find that:
F' = F

Force between two long conductor carrying current,

On performing integration:

Concept 

Newton's law of gravitation states "Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres."

Explanation 

Newton's law of gravitation can be represented mathematically as: F = G x (m₁ x m₂/ r²)

Where:

• F is the force of attraction between the two bodies.
• m₁ and m₂ are the masses of the two bodies.
• r is the distance between the centres of the two bodies.
• G is the gravitational constant, a proportional constant that in the SI system is approximately 6.674 x10^-11N(m/kg)².
• So, if you have two bodies with masses m1 and m2, and they are separated by a distance r, then the force of gravity between them is directly proportional to the product of their masses and inversely proportional to the square of the distance between them,
• Real-world applications of this law include everything from explaining the motion of planets in our solar system to the rolling of a ball down a hill. It's one of the cornerstones of classical physics and is essential in understanding the larger structure of the universe.

Infrared waves are emitted by hot bodies. They are produced due to the de-excitation of atoms.
They are called Heat waves as they produce heat falling on matter. This is because water molecules present in most materials readily absorb infrared waves. After absorption, their thermal motion increases, that is, they heat up and heat their surroundings.
Uses: Infra red lamps; play an important role in maintaining warmth through greenhouse effect.

The resolving power of a telescope is given by

So, the resolving power of a telescope depends on the diameter of the objective lens.

Force due to surface tension acts all along the circumference of the circular plate. Therefore, force required to take away of plate is,
F = T x 2πr = 70 x 2 x 3.14 x 4 = 1758.4 dyne/cm
 

Brewster's angle is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light is incident at this angle, the light that is reflected from the surface is therefore perfectly polarized.

Children think that everything around them, including toys, is alive. This example points to a prominent characteristic of the preoperational stage called ‘animism’ by Piaget. It is a result of egocentric thinking and refers to the tendency of children to assign humanistic qualities to inanimate things.

• They believe that non-living things have desires and think, feel, and act like them.
• A logical consequence of animistic thinking is the strong emotional response towards non-living objects―talking to their toys, taking care of them, and expressing their feelings towards them. 

In psychology, individual differences refer to the extent and kind of variations or similarities among people on some of the important psychological aspects such as intelligence, personality, interest, and aptitude.

According to the principle of homogeneity of dimension, an equation is dimensionally correct when each term has same dimension on both sides of the equation. 

Since left side has dimension of force so the term Pt⁻¹ will have also dimension of force. 

Thus, [P][T⁻¹]=[F]=[MLT⁻²]

or [P]=[MLT⁻¹]

We know that the dimension of momentum is [p]=[MLT⁻¹]

'A house divided against itself cannot stand' means if there is no unity within an organization or group nothing can be achieved.

Option 3 states this meaning and is the correct option. All other options imply other ideas.

Example- The management never made peace with the players, hence there was complete chaos, and the team eventually lost. Truly a house divided against itself cannot stand in the long run.

The sentence indicates that the tribes believe in the 'vagueness' i.e the uncertainty of the after-life. Out of the given options, only 'obscurity' means unclear, uncertain or mysterious. The other options, 'totality', 'tenacity', 'severity' and 'lucidity' mean 'wholeness', 'persistence', 'seriousness' and 'clarity'. Hence, the correct answer is 2.

'Spellbinding' is 'something that takes a person by complete surprise as if he/she has been under the influence of magic'.
The meanings of the other words are:
Amusing: causing laughter and providing entertainment.
Tantalising: tease someone with the sight or promise of something that is unobtainable.
Tormenting: inflicting severe physical or mental suffering.
No other option has the same meaning as spellbinding. Thus option 4 is the correct answer.
Example-The beauty of the Himalayan ranges spellbound all people.

The sentence is grammatically correct.
Hence, there is no error in the given sentence.
