Checking Statement I:

Here, as Kirti correctly remembers that her birthday is in the second half of the year, so her birthday is in July or August or September or October or November or December.

Hence data in statement I is not sufficient to answer the question.

Checking Statement II:

Here, as Kirti’s father correctly remembers that her birthday is after 31st October but before 1st December, so we can say that Kirti’s birthday is in November.

Hence data in statement II is sufficient to answer the question.

Hence, Option B is correct.

सही उत्तर 'वाक् + हरि' है।

• 'वाग्घरि' का सही संधि-विच्छेद 'वाक् + हरि' है।
• 'वाग्घरि' शब्द में 'क् + ह = ग्ह' का मेल हो रहा है इसलिए यहां व्यंजन संधि है।

Key Points

Important Points'क्' का 'ग्' होना-

• वाक् + जाल = वाग्‍जाल
• ऋक् + वेद + ऋग्‍वेद
• वाक् + दान = वाग्‍दान
• दिक् + विजय = दिग्विजय
• वाक् + धारा = वाग्‍धारा

सही उत्तर 'एकवचन के स्थान पर बहुवचन' है।

Key Points

• 'गुरू जी आ रहे हैं।' वाक्य में 'वचन' प्रयोग है- एकवचन के स्थान पर बहुवचन
• प्रस्तुत वाक्य में 'गुरु' तो एक है लेकिन आदर भाव होने के कारण बहुवचन के रूप में प्रयोग करेंगे।
• आदर या सम्मान सूचक शब्द सदैव बहुवचन के रूप में प्रयुक्त होते हैं। आदर सूचक शब्दों का प्रयोग व्यक्तिवाचक अथवा उपनाम वाचक संज्ञाओं के साथ किया जाता है।
• महाराज, साहब, महाशय, जी, बहादुर, शास्त्री, स्वामी इत्यादि शब्द आदर सूचक शब्द होते हैं।
  • शंकर जी आए हैं।
  • साहब कल जयपुर आएंगे।
  • गुरूजी आज नहीं आये।
  • गिरिराज महाराज का स्वास्थ्य ठीक नहीं है।
  • स्वामी जी ही कोई उपाय बताएंगे।
  • गांधीजी छुआछूत के विरोधी थे।

Additional Information

• 'निष्पाप' शब्द का सही संधि-विच्छेद - निः + पाप l
• 'निः + पाप' शब्द में विसर्ग संधि है, जिसकी संधि 'निष्पाप' है l
• विसर्ग संधि में यदि विसर्ग से पहले इ, उ और बाद में क, ख, ट, ठ, प, फ में से कोई वर्ण हो तो विसर्ग का ष हो जाता है।

अन्य विकल्पों का विश्लेषण:-

• गिरीश - गिरि + ईश - गिरीश शब्द में दीर्घ संधि है। दीर्घ अ, आ, इ, ई, उ, ऊ और ऋ के बाद ह्रस्व या दीर्घ अ, आ, इ, ई, उ, ऊ और ऋ स्वर आ जाएँ तो दोनों मिलकर दीर्घ आ, ई, ऊ और ऋ हो जाते हैं। इस मेल से बनने वाली संधि को दीर्घ स्वर संधि कहते हैं।
  • रमेन्द्र - राम + इन्द्र, सर्वोदय - सर्व + उदय - गुण संधि l
• जब संधि करते समय (अ, आ) के साथ (इ, ई) हो तो 'ए' बनता है, जब (अ, आ) के साथ (उ, ऊ) हो तो 'ओ' बनता है, जब (अ, आ) के साथ (ऋ) हो तो 'अर' बनता है तो यह गुण संधि कहलाती है।

Additional Information

• पास-पास स्थित पदों के समीप विद्यमान वर्णों के मेल से होने वाले विकार को संधि कहते हैं।
• संधि के तीन भेद होते हैं -
  • स्वर संधि,
  • व्यंजन संधि
  • विसर्ग संधि।
• विसर्ग संधि के उदाहरण :-
  • निः + कलंक = निष्कलंक
  • चतुः + पाद = चतुष्पाद
  • निः + ठुर = निष्ठुर
  • धनुः + टंकार = धनुष्टंकार

Let us first learn the meanings of the given words:

Reverberate (verb): be repeated several times.

Echo (verb): repeat (someone's words or opinions), typically to express agreement.

Resonate (verb): to produce or be filled with clear, continuing sound.

The idea here is to express that the end of FTX is a continuous topic of discussion, thus all the options are apt contextually and grammatically.

Hence, the correct answer is option C.

As we know that ,
Scrimp means to live on very little money and Lavish is to live extravagantly, i.e., spending a lot of money, parsimonious are means for making money.
Therefore , Lavish is opposite word of Scrimp . 

Rash means acting or done without careful consideration of the possible consequences

Some of the synonyms are- reckless, impetuous, impulsive, hasty, overhasty, foolhardy, incautious, precipitate, precipitous, premature, careless, heedless, thoughtless, imprudent, foolish

Countries need to stop and think this through and not make any rash decisions before starting a war

Due to rash attack by the enemies, the army was able to overpower them

Apparent weight of a person-

(i) When the lift moves upward with acceleration a. Then the net upward force on the person is:

R – mg = ma

∴ Apparent weight, R = mg + ma = m(g + a)

So when a lift accelerates upwards, the apparent weight of the person inside it increases.

(ii) When the lift moves downwards with acceleration a. Then the net downward force on the person is:

Mg - R = ma

∴ Apparent weight, R = mg - ma = m(g - a)

So when a lift accelerates downwards, the apparent weight of the person inside it decreases.

(iii) When the lift is at rest or moving with uniform velocity v downward/upward. The acceleration a = 0, then the net force on the person is:

R – mg = m x 0 = 0

R = mg

∴ Apparent weight = Actual weight

(iv) When the lift falls freely. If the supporting cable of the lift breaks, the lift falls freely under gravity. Then a = g. The net downward force on the person is:

R = m(g - g) = 0.

Thus the apparent weight of the man becomes zero. This is because both the man and the lift are moving downwards with same acceleration ‘g’ and so there are no forces of action and reaction between the person and the lift. Hence a person develops a feeling of weightlessness when he falls freely under gravity.

Given:

Mass of lift (m) = 250 kg, a = 2 m/s² and g = 10 m/s²

Let the tension in the string = T

According to the question, a lift is moving with acceleration ‘a’ in an upward direction.

∴ T = m(g + a)

⇒ T = 250(10 + 2) = 250 × 12 = 3000 N

Mix sugar and wheat flour mixture in water and dissolve it well. Then filter it with filter paper. Wheat flour will remain on the filter paper while sugar is obtained by filtering from water solution.

When a drug binds to a receptor to produce a pharmacologic effect, the drug may be called an Agonist.

Agonist and blocker are synonymous. An agonist is a drug that activates certain receptors in the brain. An agonist is a medication that mimics the action of the signal ligand by binding to and activating a receptor.

Piroxicam has a half-life of 45 hours and thus can be administered once a day but it can show some GI disturbance. Phenylbutazone a pyrazolone derivative is a powerful anti-inflammatory drug but its usefulness is limited by its toxicity chiefly short-term therapy. Ibuprofen is a propionic acid derivative has the same potency as acetyl Salicylate but better tolerated (fewer side effects). Indomethacin is an indole derivative more potent than ASA but inferior at doses tolerated by rheumatoid arthritis patients, quite toxic.

r% of r = 49
r² = 49 × 100
r = 7 × 10 = 70
Hence, Option B is correct.

Let the total length of the tree be X + Y meters
From the figure tan 45 = X/20 => X = 20
cos 45 = 20/Y => Y = 20/cos 45 = 20√2
X + Y = 20 + 20radic; 2 = 20 + 2 x 10 x 1.414 = 48.28 meters

The average of the last two numbers

Hence, Option A is correct.

Given, ratio of donor concentration (ND. to accpetor concentration (NA. is 0.25

Hence, the correct option is (A)

Relays are switches that open and close circuits electromechanically or electronically.

Reactance relay is used for Short transmission line

Impedance Relay is used for Medium transmission line

Admittance Relay is used for Long

transmission line

Hence, the correct option is (C)

For a DC generator

An over-excited 3-phase synchronous motor is not only used as a motor to supply the needed mechanical power but also acts as a power factor correction device.But generally prefered for power factor correction.

a transistor is a combination of two diodes, we have two junctions here. As one junction is between the emitter and base, that is called as Emitter-Base junction and likewise, the other is Collector-Base junction. A transistor is a combination of two p-n junction with their p region connected together and n region connected together.

Hence, the correct option is (B)

If currents leads 10⁰
