Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 4
  • Mysore had grown in strength under powerful rulers like Haidar Ali (from 1761-1782) and his famous son Tipu Sultan (from 1782-1799).

  • Mysore controlled the profitable trade of the Malabar Coast where the Company purchased pepper and cardamom.

  • In 1785, Tipu Sultan stopped the export of sandalwood, pepper and cardamom through his kingdom's ports and disallowed local merchants from trading with the Company.

  • He also established a close relationship with the French in India and modernised his army with their help. The British were furious.

  • They saw Haidar and Tipu as ambitious, arrogant and dangerous—rulers who had to be controlled and crushed.

  • Four wars were fought with Mysore (1767-1769, 1780-1784, 1790- 1792 and 1799). Only in the last—the Battle of Seringapatam—did the Company ultimately win a victory.

DSSSB PGT Chemistry Mock Test - 2 - Question 7

Direction: Read the following passage carefully and answer the questions. Your answer to these questions should be based on passage only.
As concern about radiation from phones and base stations continues to grow, health experts advice a change of habits-spending less time on the phone, using landline, and texting rather than calling-to cut the risk. The risk of brain cancer as a result of excessive use of phones cannot be ruled out. Reduced use of mobile phones is advised, Cancer is an extreme example. We get many cases of parents complaining that their children lack concentration, get headache and have behavioral problems. This cannot be proved, though. A scientist with ICMR said exposure to radio frequency radiation has a thermal effects, caused by holding a phone close to the body, and also a non-thermal effect which can be attributed to the induced electromagnetic effects inside biological cells. The non-thermal effect is possibly more harmful. People who are chronically exposed to low level wireless antenna emissions and users of mobile phone handsets have reported feeling several unspecific symptoms.

Q. How can the chances of brain cancer be reduced?

Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 7

The author states that the chances of brain cancer can be reduced by spending less time on phone. Instead we can use message and can use land line. Options (a), (b) and (c) contributed to the answer.

DSSSB PGT Chemistry Mock Test - 2 - Question 8

Direction: Read the following passage carefully and answer the questions. Your answer to these questions should be based on passage only.
PM's offensive and pompous reply verged on the preposterous. It is not only in consonance with certain facts, but is also wholly out of keeping with disappointment for them that a government and people noted for their high culture and politeness should have committed this serious lapse and should have addressed the GOI in a language which is discourteous and unbecoming, even if it were addressed to a hostile country. Since it is addressed to a country that is referred as friendly, this can only be considered as an act of forgetfulness. The GOI realizes that the system of government in China is different from that prevailing in India. It is the right of the Chinese people to have a government of their choice, and no one else has a right to interfere

Q. What is the difference in the system of the Government of China and India?

Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 8

China has the government of their people's choice and has a right to interfere as india has got a government of its own choice and nobody has a right to interfere.

DSSSB PGT Chemistry Mock Test - 2 - Question 10

Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?

Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 10

It is given that, excluding stoppages, the speed of a bus is 54 kmph.
⇒ Distance travelled by bus in 1 hour, excluding stoppages = 54 km.
Also, it is given that including stoppages the speed of the bus is 45 km/hr.
⇒ Distance travelled by the bus in 1 hour, including stoppages = 45 km.
(Distance travelled by bus in 1 hour excluding stoppages – distance travelled by bus in 1 hour including stoppages)
⇒ (54km−45km) ⇒ 9 km
Due to stoppages, it covers 9 km less in an hour.
Students can easily solve this question by using this trick.
Required time for the stoppage per hour,

DSSSB PGT Chemistry Mock Test - 2 - Question 11

निर्देशः नीचे दिए गए अपठित गद्यांश को ध्यानपूर्वक पढ़ें एवं उस पर आधारित प्रश्न के उत्तर दें।
चुनाव पूर्व सर्वेक्षण एवं एक्जिट पोल का लोकतन्त्र में क्या महत्त्व है? यह प्रश्न विचारणीय है। लोकतन्त्र रूपी वृक्ष जनता द्वारा रोपा और सींचा जाता है, इसके पल्लवन एवं पुष्पन में मीडिया की विशेष भूमिका होती है। भारत एक लोकतान्त्रिक राष्ट्र है। लोकतान्त्रिक राष्ट्र में नागरिकों को विशिष्ट अधिकार और स्वतन्त्रताएँ प्राप्त होती हैं। भारतीय संविधान ने भी अनुच्छेद 19 (i) के अन्तर्गत नागरिकों को अभिव्यक्ति की स्वतन्त्रता प्रदान की है, लेकिन जनता के व्यापक हित पर प्रतिकूल प्रभाव डालने वाली स्वतन्त्रता बाधित भी की जानी चाहिए। भारत जैसे अल्पशिक्षित देश में इस प्रकार के सर्वेंक्षण अनुचित हैं। देश की आम जनता पर मीडिया द्वारा किए जाने वाले चुनाव पूर्व सर्वेक्षण और चुनाव के तुरन्त पश्चात् किए जाने वाले एक्जिट पोल का भ्रामक प्रभाव पड़ता है। वह विजयी होती पार्टी की ओर झ़ुक जाती है। आज भी सामान्य लोगों के बीच ये आम धारणा है कि हम अपना वोट खराब नहीं करेंगे, जीतने वाले प्रत्याशी को ही वोट देंगे। वर्तमान में बाजारवाद अपने उत्कर्ष पर है और मीडिया इसके दुष्प्रभाव से अनछुआ नहीं है। यह कहना अतिशयोक्ति न होगी कि आज मीडिया भी अधिकाधिक संख्या में प्रसार और धन पाने को बुभुक्षित है। मीडिया सत्ताधारी और मजबूत राजनीतिक दलों के प्रभाव में भी रहता है। ये दल धन के. बल पर लोक रुझान को अपने पक्ष में दिखाने में सफल हो जाते हैं और सम्पूर्ण चुनाव प्रक्रिया को ही धता बता देते हैं। इस प्रकार सत्ता एवं धन इन सर्वेक्षणों को प्रभावित करते हैं। इन्हें दूध का धुला नहीं कहा जा सकता। भारत जैसे लोकतान्त्रिक राष्ट्र में जहाँ जनता निर्वाचन प्रक्रिया के माध्यम से अपना मत अभिव्यक्त करती है, वहाँ इन सर्वेक्षणों के औचित्य-अनौचित्य पर विचार किया जाना चाहिए। न्यायालय को यदि संविधान के अनुसार चलने की बाध्यता है, तो संसद को संविधान में संशोधन करने की शक्ति प्राप्त है। वह अपने अधिकारों का प्रयोग करके कोई सार्थक प्रयास कर सकती है।

Q. प्रतिकूल प्रभाव डालने वाली स्वतन्त्रता क्यों बाधित होनी चाहिएः

DSSSB PGT Chemistry Mock Test - 2 - Question 17

A first order reaction is 50% completed in 1.26 × 1014 s. How much time would it take for 100% completion?

Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 17

The time taken for half the reaction to complete, i.e., the time in which the concentration of a reactant is reduced to half of its original value is called half-life period of the reaction. But it is impossible to perform 100% of the reaction. Whole of the substance never reacts because in every half-life, 50% of the substance reacts. Hence, time taken for 100% completion of a reaction is infinite.

DSSSB PGT Chemistry Mock Test - 2 - Question 21

The metallic character of group 14 elements:

Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 21

The metallic character of group 14 elements increases from top to bottom because removal of electron becomes easier on moving down the group. Metallic character increases as you move down an element group in the periodic table. This is because electrons become easier to lose as the atomic radius increases, where there is less attraction between the nucleus and the valence electrons because of the increased distance between them.

DSSSB PGT Chemistry Mock Test - 2 - Question 22

Be can show coordination number four while other members show a value of six. This is because of:

Detailed Solution for DSSSB PGT Chemistry Mock Test - 2 - Question 22

The electronic configuration of Be is 1s22s2. We can see that there are only 4 orbitals in its valence shell( they are s and p). In other words, d orbital is absent. So, Be shows ccoordination no 4 and not 6 as like other members of its group.
