Correct option is (B) \(\frac{I_0}2\)

When unpolarized beam of intensity is passed through a polariser, the intensity of emerge beam will half.

I = I₀Cos²\(\theta\)

Average value of Cos²\(\theta\) = 1/2

So, I = I₀ \(\frac12\)

I = \(\frac{I_0}2\)

From lens makers formula,

\(\frac{1}{f}\) = \((\frac{μ_g}{μ _m}-1)\) \((\frac{1}{R_1}-\frac{1}{R_2})\)

When µ_m is increased but still less than µ_g, 

Means \((\frac{μ_g}{μ _m}-1)\) decreases. 

It means, \(\frac{1}{f}\) also decreases. 

Now, 

From \(\frac{1}{v}-\frac{1}{u}\) = \(\frac{1}{f}\), 

When \(\frac{1}{f}\) decreases,

\(\frac{1}{v}\) also decreases, 

Therefore, 

V increases that is distance of image increases away from lens.

The number of photoelectrons ejected per second is what determined by the intensity of light of by the number of photons falling per second.

Heat removed in 8 hours from each kg of fish 

= 1 × 2.93 × [25 – (– 3)] + 232 + 1 × 1.25 [– 3 – ( – 8)] 

= 82.04 + 232 + 6.25 = 320.29 kJ/kg

Heat removed by the plant /min

= \(\cfrac{320.29\times20\times1000}{8}\) = 800725 kJ/h

(i) Capacity of the refrigerating plant 

= \(\cfrac{800725}{14000}\) = 57.19 tonnes.

T₁ = 25 + 273 = 298 K 

T₂ = – 8 + 273 = 265 K

∴ C.O.P. of reversed Carnot cycle

= \(\cfrac{T_2}{T_1-T_2}\) = \(\cfrac{265}{298-265}\) = 8.03.

(iii) Power required :

Actual C.O.P. = \(\cfrac13\) x Carnot C.O.P. = \(\cfrac13\) x 8.03 = 2.67

But actual C.O.P. = \(\cfrac{Net \,refrigerating \,effect/min}{Work \,done /min}\) = \(\cfrac{R_n}W\)

2.67 = \(\cfrac{800725}W\) kJ/h

W = \(\cfrac{800725}W\) = 299897 kJ/h = 83.3 kJ/s

∴ Power required to run the plant = 83.3 kW.

We know that, de-brogli \(\lambda=\frac h{p}\)

\(\lambda=\frac{h}{mv}\)

\(\lambda\propto\frac1{m}\)

The mass of electron is less than mass of photon. So De-brogli wavelength of electron will greater than wavelength of photon.

(ii) C. This is to inform all the residents of Chelavoor Heights about… 

(iii) D. (3), (4) and (6) 

(iv) A. Yes, because it is the issuing body. 

(v) D. Inconvenience regretted.

If 1854 is the underlined word, the sentence can be changed into:

When was Pasteur appointed as Head of a College of Science at Lille?

If College of Science at Lille is the underlined word, the sentence can be changed into:

Where was Pasteur appointed as Head in 1854?

Pasteur gave lectures in Lille on fermentation. The chief industry in Lille was the manufacture of alcohol from beetroot, which would go wrong in a short time. Pasteur conducted experiments in their breweries. He helped a manufacturer whose beer was turning out badly, by discovering about yeast. When yeast was used to manufacture beer it stayed good for a long time. Thus Pasteur proved himself useful to the manufacturers of Lille.

According to Borges, a book is only an extension of our imagination and memory. We get access to literâture through books. Literature is a dream, a controlled dream. Borges believes that we owe literature almost everything we are, what we have been and what we will be. Our past is nothing but a sequence of dreams. He believes that there is no difference between dreaming and remembering the past. Books are undoubtedly the most astounding invention of man. It is books that serve as the repositories of great memories of all centuries and nothing else can replace books. Therefore, if books disappear, surely history would disappear and along with history man would also disappear. He says that books always retain something sacred, mortal and magical which brings happiness. Therefore, literature is very important for preserving the future of mankind.

B. Different development goals may be conflicting for a country's development.. Different development goals may be conflicting for a country's development.

• Learning of attitudes usually takes place by association 
• through rewards and punishments 
• through modelling 
• through group and cultural norms 
• through exposure to information

A. conflicting developmental goals

• We usually expect behaviour to follow logically from attitudes. However, an individual’s attitudes may not always be exhibited through behaviour. Likewise, one’s actual behaviour may be contrary to one’s attitude towards a particular topic.

It is found that there would be consistency between attitudes and behaviour when: 

• the attitude is strong, and occupies a central place in the attitude system, 
• the person is aware of her/his attitude, 
• there is little or no external pressure for the person to behave in a particular way. For example, when there is no group pressure to follow a particular norm 
• the person’s behaviour is not being watched or evaluated by others, and 
• the person thinks that the behaviour would have a positive consequence, and therefore, intends to engage in that behaviour.
