MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 4

Directions: Each of the following consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

In which month of the year is Kirti’s birthday?
Statement I:
Kirti correctly remembers that her birthday is in the second half of the year.
Statement II: Kirti’s father correctly remembers that her birthday is after 31st October but before 1st December.

Detailed Solution for MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 4

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.

MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 7
निम्नलिखित में से 'विसर्ग संधि' का उदाहरण है?
Detailed Solution for MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 7
सही उत्तर है - "निष्पाप" l
Key Points
  • '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

MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 10

MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 11

The mass of a lift is 250 kg. When it ascends with an acceleration of 2 m/s2, the tension in the cable will be (g = 10 m/s2)

Detailed Solution for MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 11

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

MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 12

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.

MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 15

Detailed Solution for MP Vyapam Electrical - Sub Engineer Mock Test - 3 - Question 19
In electromagnetism, the magnetic permeability of a material is a measure of the capability of the material to support the formation of a magnetic field within the material in response to an external magnetic field. In general, the permeability of a material depends on several factors such as the temperature, magnetic field strength, humidity and the frequency of the magnetic field. The permeability of a material is usually denoted by the symbol µ and is equal to the ratio of the magnetic flux density to the magnetic field strength. It can be expressed as µ = B/H.

Hence, the correct option is (A)
