World Poetry Day is celebrated on March 21 every year. This day is significant as it honours the role of poetry in cultural and linguistic expression. It was adopted by UNESCO in 1999 to promote linguistic diversity, revive poetry traditions, and increase awareness and understanding of endangered languages. The theme for World Poetry Day 2024 is "Standing on the Shoulders of Giants," highlighting the influence and inspiration that past poets have on contemporary poetry.

The 12th edition of the India-Italy Military Cooperation Group (MCG) meeting took place in New Delhi on March 12–13, 2024. The two-day meeting focused on new initiatives to enhance defense cooperation and military-to-military exchange between the two countries. Both sides expressed satisfaction with the proposed new initiatives.

The correct answer is BR Ambedkar.

• The Constituent Assembly formed 22 committees of which 10 were on procedural affairs and 12 were on substantive affairs.

Dyslexia is a type of learning disorder that involves difficulty in reading or recalling a sequence of letters in words (decoding) due to problems like speech sounds. It has an impact on areas of the brain that process language. It is also known as a reading disability.
Hence, this is the correct answer.

Theory of Multiple Intelligence which describes eight different kinds of intelligence is propounded by an American cognitive psychologist 'Howard Gardner'.

d ∝ 1/r

Correct option is B.

KEY CONCEPT : When a charged particle enters perpendicular to a magnetic field, then it moves in a circular path of radius.

where q = Charge of the particle

p = Momentum of the particle

B = Magnetic field

Here p, q and B are constant for electron and proton, therefore the radius will be same.

Interference is a known phenomenon in which two coherent sources of light meet and produce a resultant effect, i.e either a wave of greater or lower amplitude.
The intensity and amplitude changes depending on whether it's constructive or destructive interference. However, energy is distributed equally and hence remains conserved.

If the total energy (TE) of a body is zero, this means that its kinetic energy (KE) is equal in magnitude but opposite in sign to its potential energy (PE).

This implies KE = -PE, which provides enough energy for the body to escape the gravitational field it is in, such as Earth's.

Conservation of angular momentum is one of the key conservation laws in physics, along with the conservation laws for energy and (linear) momentum. All the top 3 options use the application conversion of angular momentum.
But the cause of fruit drop can occur due to many reasons such as a severe pest infestation can stress the tree enough to cause fruit drop, Sudden changes in temperature, particularly when high temperatures occur at or shortly after fruit set, can cause fruit drop.

A cloth covers a table. Some dishes are kept on it. The cloth can be pulled out without dislodging the dishes from the table. This phenomenon can be seen when the cloth is pulled very quickly. It is explained by the principle of inertia, not by Newton's Third Law of Motion. Inertia is the tendency of an object to resist changes in its state of motion, which is why the dishes tend to stay in place when the cloth is pulled out quickly.

When the body is in rest it is under static friction but when it starts moving (neither rolling nor sliding), the static friction slowly chngs to kinetic friction as the coefficient of static friction start decreasing and that of kinetic friction starts increasing. In case it starts rolling motion then the friction is rolling friction & if it slides then sliding fiction.

Microwaves are electromagnetic waves with wavelengths longer than those of terahertz (THz) wavelengths, but relatively short for radio waves. Microwaves have wavelengths approximately in the range of about one meter to one millimeter; with frequencies between 300 MHz (1 m) and 300 GHz (1 mm).

• Scientific notation is the method of writing, or of displaying real numbers as a decimal number between 1 and 10 followed by an integer power of 10. 
• To convert a regular number to scientific notation, we first rewrite it as a decimal, then multiply it by a power of 10.
• There is an infinite number of ways to do this for any given number, but we always prefer the one that has only a single digit in front of the decimal point. 

KEY CONCEPT :

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.

As, U=−Gm₁m₂/r, 
it can be used to describe the potential energy in a system of point charges (or radially symmetric spheres) as a function of their separation distance r, then the maximum value is zero at infinite separation.
Hence, its maximum value is zero at infinity.
 

In stationary position, spring balance reading  => mg = 49

As we know time interval will have dimensions of time so check in option for dimension of time.
Dimensions of v is "per second" or [T^-1]

In the direction of electric field the electric potential decreases. This is because electric potential is the work done against the direction of the electric field.

λ=hc/E​=1240evnm /15×103 ​=0.083 nm
Since the order of wavelength is between 10 nm and .001 nm, it belongs to X-ray. part of the spectrum.

Railway tracks are banked at curves to help the train negotiate the curve safely. The banking of the tracks ensures that the necessary centripetal force is provided by the horizontal component of the normal reaction force from the track. This reduces the reliance on friction between the train wheels and the track, allowing trains to travel safely around curves at higher speeds.

Let p0 = atmospheric pressure,

p1 and p2 = pressures inside the two bubbles

Let r = radius of curvature of the common surface

I=(I1)cosωt+(I₂)sinωt
(I²)_mean=I₁²cos²ωt+I₂²sin²ωt+I₁I₂cosωtsinωt
I₁²×(1/2)×i₂²×(1/2)+2_I1I₂×0
I_rms=√(i²)_mean=√(I₁²+I₂²/2)=(1/√2)( I₁²+I₂²)^1/2

We know that torque

1 km = 1000 m and 1 hr = 3600 sec.

Therefore,
