The logic is:

the pattern being followed here is:

(Number)² : (Number)³

1. 225 : 3375 → 15² : 15³

2. 49 : 280 → 7² : 7³ = 343 ≠ 280

3. 64 : 512 → 8² : 8³

4. 25 : 125 → 5² : 5³

Hence, ‘49 : 280’ is the odd one out. 

The logic follows here is:

Pattern: Letter increased by +1, +2, +3, +4, +5, +6 and so on.

Similarly,

Hence, "FZDQURL" is the correct answer.

The logic followed is:
Top number = (sum of the bottom number)²

225 = (8 + 7)²
225 = 15²
225 = 225
In fig 2:
49 = (3 + 4)²
49 = 7²
49 = 49
Similarly,
121 = (6 + ?)²
√121 = 6 + ?
11 = 6 + ?
? = 11 - 6
? = 5 
Hence, the correct answer is "5".

From the diagram given below:

File Extension of MS-Power Point File:

The correct file extension for a MS-Power Point file is .ppt.

Explanation:

• MS-Power Point is a popular presentation software developed by Microsoft.


• When you save a Power Point presentation, it is saved with a specific file extension that indicates the file type.


• The file extension for Power Point files is .ppt, which stands for "Power Point Presentation".


• The file extension helps the operating system and associated software identify and open the file correctly.


• If you see a file with the extension .ppt, you can be confident that it is a Power Point presentation.


• It is important to have the appropriate software, such as Microsoft Power Point, to open and view .ppt files.


• Other file extensions mentioned in the question, such as .ppf and .ptp, are not valid file extensions for Power Point files.

All the three sentences are correct. Teaching aids, when used moderately, enhance teaching efficiency. Use of teaching aids fosters motivation and they also emphasise learning by doing. Teaching aids are a means of enhancing learning without boredom and keeping the students engaged. So, they are a very important teaching tool.

As there is no horizontal acceleration is present in oblique projection horizontal component of velocity is constant

Xc ≈ 0.026 Ohms

• When an object is moving along a straight path, the magnitude of average velocity is equal to the average speed.
• Therefore, the numerical ratio of average velocity to average speed is one in a straight line motion.
• But, during curved motion, the displacement < distance covered, so the velocity < speed.

​Therefore, the numerical ratio of average velocity to average speed is equal to or less than one but can never be more than one. 

E.l = V   where,
E = electric field intensity = 12 N/C
V = electric potential = 6 J/C
=> distance between A and B, 
l = (6 / 12) m or (1 / 2) m = 0.5 m
 

Electromagnetic waves vary in wavelength and frequency. Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy.

Explanation:The induced EMF is expected to be constant in the case of a rectangular loop. In case of a circular loop, the rate of change of area of the loop during the passage out of the field region is not constant, whereas it is constant for rectangular loop.

The polarization angle (also called Brewster's angle)is defined as the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.
Brewster's Law states that the tangent of the angle of polarization is numerically equal to the refractive index of the medium.
μ = tan i ...................... (1)
From Snell's law:
μ = sinr sini​ ....................(2)
Comparing (1) and (2)
cos i = sin r = cos (2π​ - r)
i.e. i = (2π​ - r)
So, i + r = 2π​
So, as seen from the diagram, if i + r = 90^o Then the angle between reflected ray and refracted ray will be 180^o - 90^o = 90^o

Explanation:At room temperature (=300K) the noble gases are all in the gas phase, they are banging around and colliding into one another like little pool balls. At this temperature, when the atoms collide they appear to elastically bounce off of one another, but this bounce is actually a result of atomic repulsion. The atoms are traveling so fast and they approach each other so quickly that their momentum 'squeezes' them together until the atomic repulsion pushes them back apart.

Explanation:

- Inductive Circuits:
In purely inductive circuits, the current lags behind the voltage by π/2 (90 degrees). This is because in an inductive circuit, the voltage leads the current due to the phase shift caused by the presence of inductance.

- Phase Relationship:
When an alternating current passes through an inductor, a back EMF is induced in the coil which opposes the flow of current. This causes the current to lag behind the voltage in an inductive circuit.

- Mathematical Representation:
Mathematically, this phase shift can be represented as a phase angle of π/2 (90 degrees) between the current and voltage in a purely inductive circuit.

- Conclusion:
Therefore, in purely inductive circuits, the current lags behind the voltage by π/2 due to the inherent characteristics of inductors to oppose changes in current flow.

When velocity is uniform, velocity-time graph is straight line parallel to time axis. So, the slope is zero.

157900  implies that the population is believed to be within the range of about 157850 to about 157950.

In other words, the population is 157900 ± 50. The “plus-or-minus 50” appended to this number means that we consider the absolute uncertainty of the population measurement to be 50 – (–50) = 100.

We can also say that the relative uncertainty is 100/157900, which we can also express as 1 part in 1579, or 1/1579 = 0.000633, or about 0.06 percent.

Velocity of ball at top = V1 = VT + VCOM

Velocity of ball at bottom = V₂ = | VT – VCOM |

V₁ >> V₂ than other option.

∴ More pressure difference is created because

 constant

Water is used as a coolant in automobiles radiators because it has high specific heat capacity. So, it absorbs a large amount of heat for a degree rise in temperature.

A teacher should take care of each child irrespective of their disabilities. He/she should ensure the students' maximum potential. Everyone has the right to education. A teacher should ensure that his/her students derive maximum benefit from education. 
Teachers must be aware of the fact that every child is different from each other. The differences occur from physical characteristics to learning styles. The objective of education is to provide the fullest possible development of learners. The teachers should find out the different strengths and weaknesses of students before their disabilities.
Hence, the correct answer is, 'Mohan, why don't you use your crutches to go to the playground?'

As per NEP 2020, adult education curriculum framework will be developed by a new and well-supported constituent body of the NCERT that is dedicated to adult education, so as to develop synergy with and build upon NCERT’s existing expertise in establishing outstanding curricula for literacy, numeracy, basic education, vocational skills, and beyond.

Key PointsThe curriculum framework for adult education will include at least five types of programmes:-

•  foundational literacy and numeracy
•  critical life skills (including financial literacy, digital literacy, commercial skills, health care and awareness, child care and education, and family welfare)
• vocational skills development (with a view towards obtaining local employment)
•  basic education (including preparatory, middle, and secondary stage equivalency)
•  continuing education (including engaging holistic adult education courses in arts, sciences, technology, culture, sports, and recreation, as well as other topics of interest or use to local learners, such as more advanced material on critical life skills).

Thus, it is concluded that As per NEP-2020, the responsibility to develop the Adult Education Framework has been given to NCERT.

The National Education Policy 2020 aims to bring transformational reforms in school and higher education and thus shape India into a global knowledge superpower.

• This policy will usher in sweeping changes to the education policy of the country, including a renaming of the Ministry of Human Resource Development as the Education Ministry.

Key Points
