Key Points अन्य विकल्पों का विश्लेषण -

Additional Informationलोकोक्ति :- किसी विशेष स्थान पर प्रसिद्ध हो जाने वाले वाक्य को ‘लोकोक्ति’ कहते हैं।

• जब कोई पूरा कथन किसी प्रसंग विशेष में उद्धत किया जाता है तो लोकोक्ति कहलाता है। इसी को कहावत भी कहते है।
• लोकोक्ति शब्द दो शब्दों से मिलकर बना हैं – लोक + उक्ति = लोकोक्ति
• अर्थात ऐसी उक्ति जो किसी क्षेत्र विशेष में किसी विशेष अर्थ की ओर संकेत करती हैं लोकोक्ति कहलाती हैं। लोकोक्तियों को कहावत, सुक्ति आदि नामों से जाना जाता हैं।

P sits to the immediate left of S.

Hence, option A is correct.

According to the information given in the question, we can draw the following diagram.

BC = 24 m
FC = ED = 12 m
FC = 12 m
Thus point F is in the west w.r.t to point C and 12 m from point C.
Hence, the correct answer is "12 m west".

In this analogy, subtract the position number of each alphabet from 26.
M ⇒ 26 - 13 = 13
O ⇒ 26 - 15 = 11
⇒ MO : 13 11
Similarly,
H ⇒ 26 - 8 = 18
J ⇒ 26 - 10 = 16
So, right answer is 18 16

Dr. B.R. Ambedkar chaired the Drafting Committee responsible for formulating the draft constitution.

In ΔQAB, OA = OB [both are the radius of a circle]
∠OAB = ∠OBA ⇒ ∠OBA = 40°
[angles opposite to equal sides are equal] Also, ∠AOB + ∠OBA + ∠BAO = 180°
[by angle sum property of a triangle]
∠AOB + 40° + 40° = 180°
⇒ ∠AOB = 180° – 80° = 100°
We know that, in a circle, the angle subtended by an arc at the centre is twice the angle subtended by it at the remaining part of the circle.
∠AOB = 2 ∠ACB ⇒ 100° =2 ∠ACB
∠ACB = 100°/2 = 50°

Let the radius of the circle be rr and the side of the square be a.a. Then according to the question, 

  Now, Ratio of their perimeters

Let the interior angles be x and 3x 

We know that exterior angle of triangle is equal to sum of interior opposite angles.

⇒ x+3x=80^∘

⇒ 4x=80^∘

⇒ x=20^∘

So the angles are 

x=20^∘

3x=3×20^∘

= 60∘

The two triangles are congruent by SAS congruency.

Let AC be the ladder of lenth 14 m and BC = 7 m

Let angle of elevation ∠ACB = θ ∴ cos θ = BC/AC

Given statement is incorrect as there is gap in between consecutive rectangles in a bar graph.

Whenever there is reflection on any surface there is refraction also beneath the surface. 
The energy of the incident beam is partially reflected and partially absorbed. 
Even a good mirror reflects nearly 80%of the incident light only. 
At normal incidence (Incident perpendicular to the surface) there is no reflection and all the light rays pass through the surface. 
When a ray passes through a denser medium and tries to enter a rarer medium and if the angle of incidence is more than the critical angle, we say there is total internal reflection. 
The total here implies that there is no refraction at all. The entire ray is refracted. 
 
Therefore when we use totally reflecting prisms, there is no energy lost due to normal incidence from air to glass and there is TOTAL (no partial refraction) reflection inside the prism. 
Thus the light is reflected almost 100% in totally reflecting prisms and hence they are preferred even though it costs high.
 

A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century, by Isaac Newton, as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives.
Astronomical (reflecting) telescopes. In a reflecting telescope, instead of a convex objective lens, a concave mirror is used to collect parallel rays from the object and form an image at the focal point. Then the convex eyepiece lens is used to magnify this image for the viewer.
 

The Particle Model of emission and absorption is based on the idea that light is composed of discrete particles called photons, and these photons carry quantized energy. This model helps us understand how atoms and molecules interact with light by either emitting or absorbing photons during electronic transitions.

The bright colors seen in an oil slick floating on water or in a sunlit soap bubble are caused by interference. The brightest colors are those that interfere constructively. This interference is between light reflected from different surfaces of a thin film; thus, the effect is known as thin film interference.

The metals, present below hydrogen in the electrochemical series, cannot liberate hydrogen from the dilute acids.
Among the given metals only Ag is present below hydrogen in electrochemical series, so it does not evolve hydrogen with dil HCl.
Ag−I⁻dilHCl ⟶ No reaction

Let atomic weight of x = Mx

atomic weight of y = M_y

we know,

mole = weight /atomic weight

a/c to question,

mole of xy₂ = 0.1

so,

0.1 = 10g/( M_x +2M_y)

M_x + 2M_y = 100g -------(1)

for x₃y₂ ; mole of x₃y₂ = 0.05

0.05 = 9/( 3M_x + 2M_y )

3M_x + 2M_y = 9/0.05 = 9× 20 = 180 g ---(2)

solve eqns (1) and (2)

2M_x = 80

M_x = 40g/mol

and M_y = 30g/mole

Mass no. = no. of protons + no. of neutrons.

Metalloids shows both the properties of metals as well as non metals.

Areolar connective tissue is a versatile tissue found between the skin and muscles, around blood vessels, and in various other locations. It provides support and flexibility.

Abscisic acid inhibits growth in plants.

Plants primarily get rid of excess water through the process of transpiration, which involves the evaporation of water from plant surfaces, mainly leaves.
