The logic follows here is:-

From The Statement

Parrot is a bird, but 'parrot' is called 'rat'. So 'rat' is a bird.

Hence "rat" is the correct answer.

The logic followed is:

In each next step 1 line segment is deleting from the given letter.

In figure A

The given shape is the letter "E".

In figure B

One line segment get deleted from the right end

Thus we get 

In figure C

Again the one-line segment gets deleted from the right end.

Thus we get 

Similarly,

In figure D

Again one line segment will get deleted from the previous image to obtained figure D.

Thus only one figure is satisfying the pattern.

Hence, the correct answer is "Option 2".

Mrs. Sharma makes her assessment useful and interesting by using various ways to collect the information. Each way provides a different piece of information or same information with some additional inputs. For example, a written question paper gives us the idea of the person's knowledge, an oral assessment gives us an idea of the person's verbal ability and articulation, and activities may prove useful in testing child's ability to apply the knowledge practically. Activities also make assessment interesting for children.

As E=Bv, thus X has a dimension of velocity.
Also, c=1/μo​ϵo​​, where c is the speed of light.
So Y must have a dimension of velocity.
Now Z=l/CR​=l×(V/Q)​×(I/V)​=l×(1/Q)​×Q/t​=l/t​
Thus, Z also has a dimension of velocity.

• It is induced EMF of periodic EMI, So formula is:

​​​​​​​

Here w is angular speed.

From the law of conservation of mechanical energy, the potential energy of a body at height h is converted into kinetic energy when it falls down. So, the magnitude of kinetic energy just before hitting the ground is equal to the potential energy at height h which is mgh.

We have given in the information that the person is in his office for two hours hence his position must not vary for two hours, that is the horizontal part in the graph which is only observed in the graph of option c.

Given: H = 9 × 10^-5; R = 180 × 10^-6 = 18 × 10^-5
The required equation ➔ H=Rcosδ

Therefore, δ = cos^-1 1/2 

=60^o
Thus, the angle of dip is 60^o.

When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees.For any angle of incidence greater than the critical angle, light will undergo total internal reflection.

The astronomers mainly use parallax method to find distances to objects like other planets. To calculate the distance to a star or to a planet, astronomers observe it from different places along Earth's orbit around the Sun.

A conservative force is one for which the work done by the force in moving an object between two points is independent of the path taken. The gravitational force is an example of a conservative force since the work done by gravity in moving an object only depends on the initial and final positions, not the path taken. Frictional force, magnetic force, and tension force are non-conservative forces since the work done by these forces depends on the path taken.

E= ε_ocos(ωt+π/3) –1
I=I₀sin(ωt)=I₀cos{(π/2)-cot)
 =I0cos(ωt+(- π/2)) —2
By,1 and 2,
Phase difference between E and I,
=ϕ_E-V_I
=(ωt+π/3)- (ωt+(- π/2))
= π/3+ π/2
=5π/6

The process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the waveforms produced.

Moment of inertia about its centroidal axis has a minimum value as the centroidal axis has mass evenly distributed around it thereby providing minimum resistance to rotation as compared to any other axis. Also the statement-2 is correct but is not the correct explanation for statement-1.

M is mutual inductance

As 'at' and 3 are added in the equation, we get at and 3 have same dimensions i.e.1
Thus a has dimensions same as 1/t.

We know that magnitude of bulk modulus
K=[P/(dV/V)]
Now, percentage change in volume is. 10^-3 %
Therefore, (dV/V)x100=10^-3
So, dV/V=10^-5
Hence, k is,
K=40atm/10^-5=40x1.01x10⁵ /10^-5 =4.04x10¹¹ N/m² 

The force exerted by machine gun on man's hand in firing a bullet. = change in momentum per second on a bullet or rate of change of momentum

The force exerted by man on machine gun = force exerted on man by machine gun = 144 N

The wires at A and B are perpendicular to the plane of paper and current is towards the reader. Let us consider certain points.
Point C (mid point between A and B) : The magnetic field at C due to A ( ) is in upward direction but magnetic field at C due to B is in downward direction.
Net field is zero.
Point E : Magnetic field due to A is upward and magnetic field due to B is downward but 

∴Net magnetic field is in downward direction.

Net field upwards. Similarly,, other points can be considered.

 Suppose the angle between the transmission axes of the analyser and the polarizer is θ. The completely plane polarized light form the polarizer is incident on the analyser. If E₀ is the amplitude of the electric vector transmitted by the polarizer, then intensity I₀ of the light incident on the analyser is
I ∞ E₀²
 
The electric field vector E₀ can be resolved into two rectangular components i.e E₀ cosθ and E₀ sinθ. The analyzer will transmit only the component ( i.e E₀ cosθ ) which is parallel to its transmission axis. However, the component E₀sinθ will be absorbed by the analyser. Therefore, the intensity I of light transmitted by the analyzer is,
 
I ∞ ( E₀ x cosθ )²
 
I / I₀ = ( E₀ x cosθ )² / E₀² = cos2θ
 
I = I₀ x cos²θ
when light passes from polarizer it's intensity becomes half and when passed through analyser it becomes,
I = I₀ x cos²θ/2
 

The word 'malleable' is incorrectly spelled as 'mallable'. The word 'malleable' means 'that which can be easily shaped'.

An "ulterior motive" refers to a desire that is kept concealed by displaying some other cause.
Example- The ulterior motive of the conspirators was revealed during the investigation. 
Vendetta means to have a prolonged fight or unsolved issue with someone that hinders positive growth.
Propaganda is basically the spreading of news that is untrue, mostly done in order to fulfill political objectives.
Grudge means to have a constant feeling of ill will or resentment for someone/something resulting from a past insult or injury.
Ulterior motive stands for the hidden motive that is present in the things done in public sight. It can be compared to collusion.
