Important PointsInput Device: A piece of equipment/hardware that helps us enter data into a computer is called an input device. For example keyboard, mouse, etc. 

1. Keyboard:

• A simple device comprising keys and each key denotes either an alphabet, number, or number commands which can be given to a computer for various actions to be performed
• It has a modified version of typewriter keys
• The keyboard is an essential input device and computers and laptops both use keyboards to give commands to the computer

2. Joy Stick:

• It is a device that comprises a stick that is attached at an angle to the base so that it can be moved and controlled
• Mostly used to control the movement in video games
• Apart from a computer system, a joystick is also used in the cockpit of an aeroplane, wheelchairs, cranes, trucks, etc. to operate them well

3. Scanner:

• This device can scan images or text and convert it into a digital signal
• When we place any piece of a document on a scanner, it converts it into a digital signal and displays it on the computer screen

Output Device: A piece of equipment/hardware that gives out the result of the entered input, once it is processed (i.e. converts data from machine language to a human-understandable language), is called an output device. For example printers, monitors, etc. 

Printer:

• A device that makes a copy of the pictorial or textual content, usually over a paper is called a printer
• For example, an author types the entire book on his/her computer and later gets a printout of it, which is in the form of paper and is later published
• Multiple types of printers are also available in the market, which can serve different purposes

Q, R, S, T, U, and V are seated in a straight line facing North.

i) S is second to the right of T.

ii) T is second to the right of Q.

iii) R is to the immediate left of Q

iv) R is to the immediate left of Q and is second to the left of V.

Thus we can see Q is sitting Fourth to the left of S.

Hence, the correct answer is "Option 4".

Remember that pressing the "Enter" key inserts a new line or paragraph break, which creates a blank line between the two lines in the document.

Due to unpaired electron paramagnetic, N-atom in NO₂ is electron deficie nt thus, to complete octet, dimer is formed.

In N₂O₄ formation, each N-atom gets charge. Dipole-dipole repulsion increases (N— N) bond length which is larger than (N— N)covalent bond.

Thus, (a), (b), (c) and (d) are correct. 

The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction.

Covalent solid doesnot conduct electricity in molten and solid state.

(a) CO (14e), no unpaired electron, magnetic moment = 0
CO⁺ (13e), One electron is lost from bonding melecular orbital unpaired electron = 1, magnetic moment =
(b)  (15e) Unpaired electron = 1, magnetic moment =
(13e) Unpaired electron = 1, magnetic moment =
(c) Zn, Zn²⁺, unpaired electron = 0
(d) O₂ (16e), unpaired electron = 2, magnetic moment =
, unpaired electron = 1, magnetic moment =

O — H group is attached to (ene) is m ost a cidic and thus, has maximum intermolecular H-bonding.

 

Fluorine has highest electronegativity among all known elements, so it shows only negative oxidation states.

The correct answer is option  A
1-butyne can react with sodium in liquid ammonia. Because terminal alkynes have acidic hydrogen. This acidic hydrogen can replace Na in presence of liquid ammonia.

 

Molar mass = 6(12) + 10(1) + 5(16) = 162g

Lyophilic colloids have a unique property of protecting lyophobic colloids. When a lyophilic sol is added to the lyophobic sol, the lyophilic particles form a layer around lyophobic particles and thus protect the latter from electrolytes. Lyophilic colloids use for this purpose are called protective colloids.

= 2.53/106   2.59 × 10^-2  5.9 × 10^-2
0.238 × 0.25          = 1.18 × 10^-3

250 ml - 0.238

S(g) + 6F(g) → SF₆(g)
∆rH = ∑∆Hreactant -  ∑∆H_product
= (275+6 80) - (-1100) 
= 1855
So,  bond energy of (S—F) = 1855/6 = 309.16 kJ mol^-1

Among alkali metals, melting point decreases as the strength of metallic bonding decreases with increasing size of the atom. Thus, Cs has the lowest melting point (28.5°C) and will melt at 30°C.

NaHCO₃ + H₂SO₄ →  Na₂SO₄ + H₂O + CO₂

Recycling of materials and energy will lead to decrease in environmental pollution

Lead does affect the kidney and CNS but its first target is RBC and through that onlt it travels inside the body to CNS and kidneys.

Making the mentally retarded students learn through concrete experiences and making them apply the learned skills will surely work for mentally retarded children. Therefore, it becomes important for the teacher to plan out instructions for clear understanding of the concepts. 

According to NEP 2020, A good educational institution is one in which every student feels welcomed and cared for, where a safe and stimulating learning environment exists, where a wide range of learning experiences are offered, and where good physical infrastructure and appropriate resources conducive to learning are available to all students.

Key Points 

 Some important fundamental principles of the NEP 2020 are- 

• Full equity and inclusion as the cornerstone of all educational decisions to ensure that all students are able to thrive in the education system.
• The 360-degree holistic report reflects in great detail the progress as well as the uniqueness of each learner in the cognitive, affective, and psychomotor domains.
• Emphasis on conceptual understanding rather than rote learning and learning-for-exams.
• Promoting self-assessment and the peer assessment done by the student in the classroom.
• Learning how to learn:- The main goal of the school education regulatory system must be to improve educational outcomes so that children can implement the acquired knowledge and skills in real life.
• Respect for diversity and respect for the local context in all curriculum, pedagogy, and policy, always keeping in mind that education is a concurrent subject.
• Learning should be done in various methods, and teachers should focus on conceptual learning in a meaningful way.
• Establishment of the linkage of the concepts with the environment or we can say that the linkage of the school with the home.
• Promoting multilingualism and the power of language in teaching and learning.
• It emphasizes group work as well as individual work, NEP 2020 links the study to the curriculum.
• So by all these references, a 360-degree holistic progress report card, and learning how to learn are the key features of the NEP 2020.

Hint

• Course content should not increases according to the NEP 2020, the learning of the lessons are done in different methods such as hands-on activities, and experimental way of learning.
• The curriculum should be flexible did not standardized.
