The work done on gas during compression increases the kinetic energy of molecules and hence temperature of gas rises.

During evaporation, fast moving molecules escape from liquid. Hence average kinetic energy of molecules left behind is decreaesd. This will reduce temperature & causes cooling.

As automobile moves, work is being done against force of friction. This work is converted in to heat and it increases the temperature. As P a T, increase in temperature will increase pressure.

(C) Alkylating agents

(B) Transition

A particle is said to execute simple harmonic motion if it moves to and fro about a mean position under the action of a restoring force which is directly proportional to its displacement from the mean position and is always directed towards the mean position.

Correct option (A) DNA

The number of hydrogen bonds between adenine and thymine in DNA is Two.

(C) Thymine dimers

Correct answer is (c) virtual and inverted

Given:

Height of pole is 75 inches                                

Calculation:

Caterpillar crawls 5 inches in a day and slide down 4 inches in night

Total distance cover by caterpillar day and night = 5 - 4

⇒ 1 inches

Total distance to cover by caterpillar in 70 days = 70 inches

Remaining = 75 – 70

⇒ 5 inches

Caterpillar takes 1 day to cover 5 inches

Total days required to reach the top = 70 + 1

⇒ 71 days

∴ It will reach at the end of 71 days.

The Correct option is  A. 1000

The Correct option is C. 0 Ω

D. both B and C

Rapid decline in death rate/rapid decline in MMR/Rapid decline in IMR/increase in no. of individual in reproductive age.

H = i²Rt

300 = 2² x R x 15

⇒ R = 300/60 = 5Ω

Now, for i = 3A, t = 10s, R = 5Ω

H = 3² x 5 x 10 = 450 J

Correct Answer is: (b)

Correct Answer is: (d) v = √(u² + α/u²)

Let l be the length of each plate and u_x = u = constant.

∴ the time of travel between the plates is given by t = l/u.

Let a be the constant acceleration in the y-direction.

∴ v_y = at when the particle emerges from the plates.

∴ v² = u_x² + v_y² = u² + a²t² = u² + a² l²/u² = u² + α/u².

Bond order of 

C2^2- = 3

N2^2- = 2

O2^2- = 1

Author say about statement memories to the mind of the writer, poets have good memories. They write out of their imagination and experiences. Politicians on the other hand have worst memories because of their statements which created lot of controversies.

Correct option is D) from / about

(d) Cimetidine

The drug cimetidine was designed to prevent the interaction of histamine with receptors present in the stomach wall.

Correct option is (a) Ag

Correct option is (a) Be 

Melting point of Be is 1560 

Melting point of Mg is 924 

Melting point of Ca is 1124 

Melting point of Sr is 1062

(a) O < S < Se < Te > Po

As we go down the group as the metallic character increases, the melting point increases for group 16 elements. But due to its packed structure and lesser shielding of electrons, Te has the highest melting point among them. 

So, the correct order is O < S < Se < Te > Po

Polar molecules = H₂O, NH₃, HCI

Non polar molecular - BeF₂, BF₃, CCl₄

(i) Health is Wealth 

Health has a great importance in human life. If you are healthy you can do everything in life. But if you are not feeling well, you will never do your work neatly. Man can achieve his goal easily if he or she is healthy. Unhealthy person falls flat everywhere. Only a healthy man has a sound mind. A sound mind keeps a person on the path of progress. Thus, it is proved that health is the real wealth for human being.

(ii) A Book Fair 

Recently a book fair was organised in Gandhi Maidan, Patna. My class teacher organised a trip to the book fair. All the students were permitted to visit the fair. All of us reached to the book fair at 11:00 a.m. After buying ticket, we entered the fair. There were a number of stalls. It was amazing to see a lots of book of various subjects. We saw subject books, cookery book, comic books, Autobiography, Biography, Novels, Magazines, books of Astrology and many more. Different books are written by different writers. I bought few story books. There was a stage where folk dance was being performed. There were also some stalls selling food items. Finally we returned from the book fair.

(iii) Adult Education 

Adult education is quite necessary for those who are deprived of getting their early education. Adult person should be literate. Our government has established many adult education centre where uneducated people learn how to write and read books of their own language. They are taught at such centre at night. The government wants to educate all to know their rights. If everyone gets education, our country will be developed. So adult education is the backbone of our education system which makes our country prosperous.

He helps poor people by arranging school fee for their children. He is really a good person. 

Ionization Energy: The energy required to remove an electron from the outer most orbit of a neutral gaseous atom is called Ionization energy. 

Effecting factors of Ionization Energy : 

(1) Nuclear charge : More the nuclear charge more is the Ionization Energy. 

(2) Screening or shielding effect : More the screening effect, less is the Ionization Energy

(3) Penetration power of the orbitals : More the penetration power, more is the Ionization Energy. 

(4) Stable configuration : More the stable configuration more is the Ionization Energy. 

(5) Atomic radius : More than the atomic radius, less is the Ionization Energy.

Health is Wealth- Health is wealth is an old saying. A healthy person is able to produce all wealth for himself and for others. Not only this but he can also enjoy wealth and produce more. Suppose a man has a first class master's degree, but he has no health. He catches cold. He catches flu. He has T.B. and other such diseases. How can he produce wealth and enjoy it? Health depends on correct living, pure water and fresh air. It also depends on good food, necessary rest and equally necessary physical work or exercise. It a man cares for all these and has limited desires, he can maintain good health. Then he can produce more wealth and he can enjoy it.

Answer: Characteristic features of nuclear force i. Nuclear forces are short range attractive forces (range 2 to 3 m) while coulomb's forces are of infinite range may be attractive or repulsive.Nuclear forces are charge independent forces, while coulomb's force acts only between charged particles.
