The correct answer is Spleen.

Spleen is an organ on the left side of the abdomen below the stomach. 

It performs two major functions:

1. Storage of blood - Blood vessels of spleen can alter their thicker and become wider or narrower depending on the situation. In case of emergency situations like trauma & severe injuries where a lot of blood gets lost, the spleen expand its vessels and hold the blood. This reserve blood is then transported to the organ where blood is required. For this reason the spleen is also called the blood bank of human body.
2. Filtration of blood - Spleen filters the blood & removes the old & dead RBCs. It acts like a maze from which healthy RBCs can easily pass while the old & dead RBCs get stuck in it. These are then broken down in the spleen by macrophages. For this reason the spleen is also called as The Graveyard of RBCs.
   

Additional Information 

Heart:

• The heart is a mesodermally derived organ, that is present in the thoracic cavity, in between the two lungs, slightly tilted to the left. It has the size of a clenched fist. It is protected by a double-walled membranous bag, pericardium, enclosing the pericardial fluid.

Liver:

• The liver is the largest gland of the human body. It performs the function of detoxification of harmful substances in the body
• For example, it converts harmful ammonia into urea,  It also breaks down alcohol and other such substances in the blood. 

Bone marrow:

• Bone marrow refers to the tissue located in the hollow interior of long bones. It is composed of adipose tissue, areolar tissue, and blood cells.
• Bone marrow is mainly of two types – red and yellow

In education process aim, content and methods are evaluated.

Evaluation is concerned with assessing the effectiveness of teaching, teaching strategies, methods and techniques. It provides feedback to the teachers about their teaching and the learners about their learning.

Diagnostic evaluation has a placement function and so takes place before instruction. It is used to determine underlying causes of learning difficulties. Diagnostic evaluation may include administration of standardised achievement tests, standardised diagnostic tests, teacher-made tests, observation and checklists. Scoring and interpretation can be normative (based on norms) or criterion-referenced. Results are usually shown as an individual profile of sub-skills.

The teacher must provide ask a few more questions on the same topic, so that the student arrives at the exact correct answer. The student thus would be left with a lasting impression and hence will not forget it for long time.

strain energy=1/2×stress × strain Work done by a force on a wire
W =2LAy(ΔL)²/2L
=1/2(yALΔ/L)ΔL
=1/2​(yΔL/L)(ΔL/L)(AL)
=1/2(Stress)(Strain)(Volume)
(Work)/(volume)=1/2*(stress)(strain)

The period of a particle in circular motion is the time taken to complete one full revolution. The period is given by T = 2π/ω, where ω is the angular velocity. Angular acceleration, α, does not affect the period directly. The angular acceleration determines how quickly the angular velocity changes, but it does not affect the time taken for one complete revolution. Therefore, if the angular acceleration is doubled, the period of the particle's motion will remain the same.

Dimension of N = [L - 3]

At the highest point of its flight, the vertical component of velocity is zero and the only horizontal component is left which is u_x = u cosθ
Given θ = 45⁰

When an object is thrown from a height a continuous gravitational acceleration acts upon the body and hence time of flight can written equal to√2gs when we consider initial velocity to be zero. Now as we can see even if initial velocity is not zero, time of flight does not depend upon the mass of the body. Hence the time of flight is always the same ideally.

Let coefficient of friction be μ, then retardation will be μg.
From equation of motion.

v = u +at

0 = 6 - μg × 10

or μ = 6/100 = 0.06

Though water and ammonia are covalent molecules, they have a net dipole moment due to their distorted structure than the ideal one. Hydrochloric acid has a linear molecular structure but its net dipole moment is towards the Hydrogen atom. But methane has a symmetrical tetrahedral structure and its net dipole moment is zero hence it doesn’t behave as a permanent dipole. Methane solvents are therefore non-polar solvents.

Answer :- d

Solution :- The negative sign is just a convention and it signifies that the direction of E is opposite to the direction in which potential increases.

Voltage is induced due to change in the magnetic flux through a closed loop.
Here 
Magnetic Flux = ϕ=BA=const.
Hence
Induced EMF = dtdϕ​=0
Induced current =i=E/R=0

Given that λ = 200nm, d=700nm
θ = λ/d
We know that maximum angle can be 90⁰
No of rings that can be obtained say n,

If θ is so small then −

In this question, the cars are identical means the coefficient of friction between the tyre and the ground is the same for both the cars, as a result, retardation is the same for both the cars equal to mg.
Let first car travel distance s₁, before stopping while second car travel distance s₂, then from v² = u² - 2as

Consider the surface facing upwards having points A, B, C and D in anticlockwise direction when viewing towards the surface from above. Let this be S
flux = S×B
As the flux increases, by Lenz's Law the induced current will be in the direction C B A D C, so as to oppose the increase in flux.

The sole reason is 'refraction' in a single word. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves. Water waves travel fastest when the medium is the deepest. Thus, if water waves are passing from deep water into shallow water, they will slow down. But here it is traveling from shallow water to deep water, then the waves bend in the opposite direction.

Total initial angular momentum = I₁ω₁ + I₂ω₂ 

When the discs are joined together, total moment of inertia about the axis becomes I₁ + I₂​.

Let the angular speed of the two-disc system be ω.

Then, from conservation of angular momentum:

Weight is a force caused by gravity. The weight of an object is the gravitational force between the object and the Earth. The more mass the object has the greater its weight will be. Weight is a force, so it's measured in newtons.

 Answer :- b

Solution :- In a purely inductive circuit (an AC circuit containing inductance only) the current lags behind the voltage by π/2

 Option is not correct because there is relation between current & voltage in inductance

Velocity of efflux when the hole is at depth h, v = √(2gh).
Rate of flow of water from square hole

Rate of flow of water from circular hole

According to problem

 

d ∝ 1/r

The formula for magnetic flux is Φ = B × A × cosθ, where θ is the angle between the magnetic field (B) and the normal to the surface (area vector A).

Since the plane of the strip is at 60° to the field, the normal is at 30° to B.

Given: Φ = 1 mWb = 1 × 10⁻³ Wb, A = 0.02 m², θ = 30°.

So, B = Φ / (A × cos30°)
cos30° = √3/2 ≈ 0.866
B = (1 × 10⁻³) / (0.02 × 0.866) = (1 × 10⁻³) / 0.01732 ≈ 0.058 T

Therefore, the correct answer is 0.058 T.

Block will slip on the slab as F > f_lim Hence kinetic friction acts between block and slab,

Components connected in parallel provide alternative pathways for current flow. When cells are connected in parallel, the total voltages that they provide does not change. For example, when two or more 2 V cells are connected in parallel, they still provide a total voltage of 2 V.

Explanation:

If a vector is multiplied by a scalar as in  pA^→ ,  then the magnitude of the resulting vector is equal to the product of p and the magnitude of  A^→, and its direction is the same as  A^→ if p is positive and opposite to  A^→ if p is negative.

Distributive law for scalar multiplication:

p(A^→ +B^→ )=pA^→ +pB^→ 

Given:

t₁ = 39.6 s
t₂ = 39.9 s
t₃ = 39.5 s

Calculate the mean time

t̄ = (t₁ + t₂ + t₃) / 3

t̄ = (39.6 + 39.9 + 39.5) / 3

t̄ = 119.0 / 3 = 39.67 s

Calculate the mean absolute error

Δt = (|t₁ − t̄| + |t₂ − t̄| + |t₃ − t̄|) / 3

Δt = (|39.6 − 39.67| + |39.9 − 39.67| + |39.5 − 39.67|) / 3

Δt = (0.07 + 0.23 + 0.17) / 3

Δt = 0.47 / 3 = 0.16 s

Final Result:

t = (39.67 ± 0.16) s

Explanation:The induced electromotive force in any closed circuit is equal to the negative of the time rate of change of the magnetic flux enclosed by the circuit.
