Dear friends, 

Have you ever visited the Intensive Care Unit or Trauma Centre of a hospital? If not, you should do so without losing time because when you make a visit to these centres, you get to see the pitiable condition of accident victims. You will see youngsters, who had their whole life in front of them, lying with their limbs amputated. You have the dear ones of these victims, some of from are in a vegetable condition, sitting next to them, hoping that their sons or daughters would open their eyes and recognize them. What is behind all this grief? Lack of road safety. 

I’m here to address you on road safety as our college is celebrating Road Safety Week in association with the RTO. I want to create awareness about the traffic rules to be followed. Isn’t it ironic that we have to be fined rules which have been formulated for our own safety? 

Dear friends, when you speed up, when you abstain from wearing a helmet, when you use the mobile while driving, please remember that it’s your life and you can’t play with your life. Be careful, be safe and don’t endanger the safety of others. Thank you. 

Have a safe future.

Dear Sir 

This is to bring to your notice that the street lights of second cross of Kariappa Colony have not been functional for the past one month. It has become almost impossible for the residents of this area to move about after 7:00 p.m. as there is total darkness. I am sorry to inform you that there have been a few cases of theft and eve-teasing too as anti-social elements are taking advantage of the situation. 

As citizens, one of the basic amenities that we are entitled to enjoy is properly lit roads. We have already complained, but no action has been taken. We request you to act immediately to ensure that the area gets proper lighting through street lights. 

Thank you.

Yours faithfully, John

Dear friends,

It gives me great pleasure to speak to you about the Library Week that our college has organized from 2nd to 10th of November this year. Reading makes a man perfect. The aim of celebrating this week is to inculcate the reading habit among students. As part of the celebration, new arrivals in the reference section such as encyclopedia and dictionaries and general books will be displayed. Orient Blackswan and Cambridge University Press are putting up an exhibition. We have invited Dr. Shobha Devi to inaugurate the exhibition and interact with students. Other authors like Smt. Shashi Deshpande and Dr. Patil will also pay us a visit. During the week, a literary quiz competition will be organized. The Reading Section will have more new magazines of general interest. 1 request all of you to spend as much free time in the library as you can. 

Thank you.

Given:

5 men(M) with 7 boys(B) can earn Rs. 4185 in 7 days

2 men(M) with 3 boys(B) can earn Rs. 1230 in 5 days.

Calculation:

If 5 men with 7 boys can earn Rs. 4185 in 7 days

In one day,

⇒ 5M + 7B = 4185/7

⇒ 5M + 7B = 597.85      ____(1)

If 2 men with 3 boys can earn Rs. 1230 in 5 days

In one day,

⇒ 2M + 3B = 1230/5

⇒ 2M + 3B = 246      ____(2)

To solve equation (1) & (2) we have to make either the number of men or number of boys equal.

Thus,

Multiply by 2 in equation (1) and multiply by 5 in equation (2)

⇒ 10M + 14B = 1195.7      ____(3)

⇒ 10M + 15B = 1230      ____(4)

Subtracting equation (3) from (4)

⇒ B = Rs. 34.3 per day

Substituting this in any of the equation (1) or (2) we can find the daily wage of 1 man.

Thus, solving equation (2)

⇒ 2M + 3 × 34.3 = 246

⇒ 2M = 246 – 102.9

⇒ M = Rs. 71.55 per day

Now, daily wage of 7M + 6B 

⇒ 7 × 71.55 + 6 × 34.3

⇒ 500.85 + 205.8

⇒ Rs. 706.65

Required number of days = 21189/706.65

⇒ 30 days (approx).

∴ Time will 7 men with 6 boys earn Rs. 21189 in 30 days.

Correct option is D) he has passed his exams

Correct option is A) study hard

Correct option is B) on her own

Correct option is C) arrival

Correct option is D) arrived

Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

v = v λ (Derivation) 

(a) 340 = 256 λ 

λ = 1.33 m 

(b) 340 = v (0.85) 

 v = 400 Hz 

Angular momentum, L = mvr = \(\frac{nh}{2\pi}\)

Here, n = 2 (given)

\(\therefore\) L = \(\frac{2h}{2\pi}\) = \(\frac{h}{\pi}\)

The answer is: \(\frac{h}{2\pi}\)

(D) Dipole moment is a scalar quantity and has magnitude charge equal to the potential of separation between charge

Dipole moment is a vector quantity and has magnitude of 2qa and it is in the direction of the dipole axis from −q to q

Hydrarch:

• This succession takes place in wet areas
• This takes place from hydric to mesic condition
• This starts from phytoplankton stage

Hydrarch succession

The pioneers are the tiny phytoplankton substituted by free-floating angiosperms with time,
Rooted hydrophytes, sedges, grasses and eventually the trees are replaced by free-floating angiosperms.

Again the climax will be a forest, and the water body is turned into land over time.

As, 

\(\frac{R_1}{R_2}\) = \([\frac{A_1}{A_2}]^{1/3}\) 

= \([\frac{125}{27}]^{1/3}\) 

= \(\frac{5}{3}\) 

∴ R₁ = \(\frac{5}{3}\) x R₂ 

= \(\frac{5}{3}\) x 3.6

= 6.0 fermi.

Answer: (c) \(E+h\nu\)

Energy of incident ray = threshold energy + (K.E)_max

\(h\nu=(h\nu_0)+E....(1)\)

\(\Rightarrow E=h\nu-h\nu_0\)

In the second case, threshold energy remains the same

\(h(2\nu)=(h\nu_0)+(K.E)_{max}....(2)\)

By (1) & (2) eqⁿ

(K.E)_max=\([h\nu-h\nu_0]+h\nu\)

\(K.E = E+h\nu\)

Infra-red waves are the electromagnetic waves of frequency range 3 x 10¹¹Hz to 4 x 10¹⁴Hz. 

Therefore, 

The given wave of frequency 5 x 10¹¹Hz lies in infra-red region.

Applying Lenz’s law, 

Direction of the induced current in the loop will be anti – clockwise.

Metal A has higher threshold frequency, 

We know that for a given photosensitive material, 

The stopping potential varies linearly with the frequency of the incident radiation. 

Also, 

Work function,

φ₀ = hv₀ 

Also, 

φ₀ = e × magnitude of intercept on potential axis. 

Here for metal A, 

y – intercept is more negative for metal A.

Among the common STs-gonorrhea, syphilis, genital herpes, chlamydiasis, hepatitis-B, AIDs etc., hepatitis-B, and AIDs are not infections of the reproductive organs though their mode of transmission could be through sexual contact also. All other diseases are transmitted through sexual contact and are also infections of the reproductive tract.

Parthenocarpy is the process of developing fruits without involving the process of fertilization or seed formation. Therefore, the seedless varieties of economically important fruits such as orange, lemon, water melon etc. are produced using this technique. This technique involves inducing fruit formation by the application of plant growth hormones such as auxins.

The correct answer is East to west.

• Bay of Bengal current is the main reason of rainfall in West Bengal occurs due to the summer monsoon. The summer monsoon normally arrives in the South Bengal during 5 - 10 June.
• 75% of the total rainfall in India occurs due to the South-west monsoons.
• Southwest monsoon is the rain-bearing seasonal winds that flow from the Arabian Sea to the mainland of India from the South-West direction.
• The monsoon season stretches from June to September.
• The average annual rainfall varies in the different parts of the state.
  • The northern region receives heavy rainfall, ranging from about 200 to 400 cm.
  • The coastal areas, Gangetic plains, and the central parts of the state receive about 150-200 cm of rainfall.
• With the arrival of the monsoons, low pressures in the Bay of Bengal region generally lead to storms in the coastal areas.

Correct option (3) Sm³⁺

Explanation:

Sm⁺³ (Yellow)

Due to presence of unpaired e^-

The correct answer is Ozone layer.

OZONE LAYER:

• The ozone layer is an area or a continuous region in the stratosphere of the earth that includes high concentrations of ozone(O3) and protects the earth from the sun's harmful ultraviolet radiation.
• It has the ability to absorb the sun's harmful ultraviolet radiation, which can damage life on Earth.
  • UV radiation, which is made up of various types of photons, is found in sunlight. UVA and UVB rays are the two forms of UV radiation you're probably most familiar with.
  • These rays can have a variety of effects on your skin.
  • The comparison between the UV A and UV B is :

• The ozone layer thus doesn't allow the penetration of only UV B radiations coming from the sun to the earth. 

Hence, the following harmful radiations from the sun are absorbed by the ozone layer is - UV B (Ultraviolet Radiation or Rays B)

Uterus is found in female body which is single and it is also called womb. The shape of the uterus is like an inverted pear. It is supported by ligament attached to the pelvic wall. The uterus opens into vagina through a narrow cervix. The cavity of the cervix is called cervical canal which alongwith vagina forms the birth canal. The wall of the uterus has three layers of tissue. The external thin membranous perimetrium, middle thick layer of smooth muscles myometrium and inner glandular layer called endometrium that lines the uterine cavity. The endometrium undergoes cyclical changes during menstrual cycle while the myometrium exhibits strong contraction during delivery of the baby. 

Following are the indirect ways of the transmission of diseases:– 

(a) Vehicle borne transmission – When transmission of infection occur through water, food, blood, tissue and organ, it is called vehicle borne transmission. For example, Typhoid, Cholera, Dysentry, Hepatitis, etc. 

(b) Vector borne transmission – When diseases are transmitted through a vector, it is called vector borne transmission. Ex-Malaria. 

(c) Air borne transmission – When droplet nuclei and infected dust are responsible for transmission, it is called air borne transmission. For example Influenza, Tuberculosis etc. 

(d) Fomite borne transmission – Apart from air and water, non-living substances are responsible for the transmission of disease, then it is called fomite borne transmission. For example–dirty cloth, handkerchief, cup, glass, which produce the diesease like typhoid & infection of eye and skin. 

(a) Autogamy – Pollination is achieved within the same flower. Tansfer of pollen grains from the anther to stigma of the same flowr. Autogamy is such flowers requires synchrony in pollen release and stigma respectively. 

Geitonogamy – Transfer of pollen grains from the anther to the stigma of another flower of the same plant. Although geiotonogamy is functionally cross-polination involving pollinating agent, genetically. It is similar to autogamy since the pollen grains come from the same plant.

Xenogamy – Transfer of pollen grains from the anther to the stigma of a different plant. This is the pollination which brings genetically different types of pollen grains to the stigma. 

(b) A special character of sexual reproduction in angiosperm is the interaction of pollengrain, male gametophyte with massive sporophytic tissue of pistil (stigma and style) before discharging the male gametes near the egg. Only after the elucidation of self-incompatibility, the importance of pollen-pistil interactions become apparent. All events from falling of pollengrains on stigma to the entering of pollentube into the ovule is called pollen-pistil interaction. The sequences of pollen pistil interaction are– 

Pollen on stigma 

      ↓ 

Pollen adhesion 

     ↓ 

Pollen hydration 

      ↓ 

Pollen germination 

      ↓ 

Pollen tube into the stigma 

           ↓ 

Pollen tube growth through the style 

           ↓ 

Pollen tube enters into the ovule 

• Gametes (sperm and ova) are haploid cells. 

The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes)

• The steps of fertilization in humans always involve the joining of an egg and sperm. 
• In natural conception, the male sperm fertilizes the female egg inside the woman's body. 
• While many think fertilization occurs in the ovary, it actually takes place in the fallopian tube just outside the ovary.

Biomagnification is the process of accumulation of toxic compounds in body.
