Naresh loves to work without supervision and set goals that are challenging, but not impossible. He learns best in solitude; thus he is a intrapersonal learner. The intrapersonal learners, as opposed to interpersonal, are the ones who work and learn best when they are alone.
They are also motivated by internal forces, rather than external ones. So, Naresh is motivated by internal forces.

In teaching field, the first and the foremost step any teacher should adopt is to understand the background of the students. This is because it will help the teacher to analyse the level of the students and will help him to deliver quality lectures to them. This can also help him in preparing the lecture and deciding the teaching aids to be used for the students.

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

The spectrum of colors produced by incandescent lights is continuous, more similar to that which is produced by the sun, and incandescent lights transmit more red wavelengths than fluorescent light.

• 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
 

NOTE : If we take individual length for the purpose of calculating the magnetic field in a 3-Dimensional figure then it will be difficult.
Here a smart choice is divide the loop into two loops.
One loop is ADEFA in y-z plane and the other loop will be ABCDA in the x – y plane.

We actually do not have any current in the segment AD. By choosing the loops we find that in one loop we have to take current from A to D and in the other one from D to A. Hence these two cancel out the effect of each other as far as creating magnetic field at the concerned point P is considered.
The point (a, 0, a) is in the X-Z plane.
The magnetic field due to current in ABCDA will be in + ve Z-direction.

NOTE : Due to symmetry the y-components and xcomponents will cancel out each other.
Similarly the magnetic field due to current in ADEFA will be  in x-direction.

∴ The resultant magnetic field will be

For x<0
F = −dU/dx = −kx
ma = −kx
or a = −kx/m
−ω^2₁x = −kx/m
ω₁ = (√k/m)
T₁ = 2π(√m/k)
For x>0 U = mgx
F = −dv/dx = −mg
But E = 1/2mv²₀
v₀ = (√2E/m)
It is speed at lowest point
T₂ = 2v₀/g
= 2/g(√2E/m)
T = T₁/2 + T₂
= π(√m/k) + 2/g(√2E/m)

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.

Beta(central Maxima) = 2 * lambda * D(distance of the screen) / d(distance between slits)
beta = 2 m, wavelength = 500nm = 5 ×10^-7m & d = 0.1mm = 1×10^-4m
► 2 = 2 × 5 × 10^-7 * D/10^-4
► 1 = 5 × 10^-3 D 
► D = 1000/5
► D = 200m

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

• NEP 2020 is based on the principle that education must develop not only cognitive capacities but also social, ethical, and emotional capacities and dispositions.  
• < />NEP-2020 has given emphasis on conceptual understanding, creativity and critical thinking, human ethical values, and constitutional values.
• < /> It proposes that experiential learning should be encouraged to promote conceptual understanding as experiential learning refers to learning by gaining experience through active involvement. 
• As per National education policy 2020, education must adopt experiential learning including hands-on learning, arts-integrated and sports-integrated education, story-telling-based pedagogy, etc.

Hence, it can be concluded that National Education Policy 2020 states that learning should be experiential.

Rule- If the reporting verb is in the present or future tense, the tense of the verb in the reported speech is not changed at all. 
Thus, as the tense of the sentence is present, it is to remain the same. Option 2 is correct.
