Benjy was swimming so slow that a crab saw his toe and wanted to try and bite it. Benjy saw the crab moving towards his toe. He got frightened at the mere thought of his toe in the claws of the crab.

Ray had paid the man far more than what the watch was actually worth,it is very unlikely that the man would return. But at the same time ,he seems to appreciate his generosity and when Ray looked into his eyes he saw gratitude and they seemed to say, “Thank you.” That is why he left a note saying that he would be back to pick up the watch as soon as he could and wished Ray a Merry Christmas.

“The watch was nothing special and yet had great powers", because it was something that could be exchanged for money and a way to lead people out of a bad situation.The older man got the money he needed without hurting Ray .On Christmas Eve ,it had saved the two men who entered the shop, from doing something they might later have been sorry for.

The man might have informed his friend that Ray was deaf and there was no need to worry about anything.

Ray,being deaf and dumb, communicated with him by writing the words"May I help you"on a notepad .He smiled at his unfriendly face, then pointed to his ears and shook his head from side to side indicating to the visitor that he was deaf.

(d) 3.4 x 10³J

K . E  = \(\frac{3}{2}\)RT = \(\frac{3}{2}\) x 8.31 x 273

= 3.4 x 10³J

Correct answer is  (a) \(\frac{PV}{kT}\)

(d) Carbon dioxide

(b) S_p – S_v = R/28

(b) Rs 18000, Rs 28800, Rs 32000

Let the incomes of A, B and C last year be Rs 3x, Rs 4x and Rs 5x respectively. 

A’s income last year : this year = 4 : 5 

∴ A’s income this year = \(\frac54\times\) Rs 3x = Rs \(\frac{15x}{4}\) 

B’s income last year : this year = 2 : 3 

∴ B’s income this year = \(\frac23\times\) Rs 4x = Rs 6x 

C’s income last year : this year = 3 : 4 

∴ C’s income this year = \(\frac43\times\) Rs 5x = Rs \(\frac{20x}{3}\)

∴ Ratio of present incomes of A, B, C

= \(\frac{15x}{4}\) : 6x : \(\frac{20x}{3}\)

= \(\frac{15x\times12}{4}:6x\times12:\frac{20x\times12}{3}\)

= 45 : 75 : 80

Given, 45x + 72x + 80x = 78800

⇒ 197x = 78800 ⇒ x = \(\frac{78800}{197}\) = 400

∴ A’s present income = 45 × 400 = Rs 18000 

B’s present income = 72 × 400 = Rs 28800 

C’s present income = 80 × 400 = Rs 32000

As we know that correlation coefficient measures the degree of relationship between the ‘ variables; such as height and weight of persons, ages of husbands and wives, demand and supply of items etc. Whereas the method of association of attributes measures the degree of relationship between the attributes; such as sex and literacy, literacy and employment, intelligence and employment etc.

According to Thomson’s atomic model electrons were embedded in a sphere of positive charge. This implies that according to Rutherford’s gold foil experiment in which the alpha particles which are positively charged must be reflected or deflected in large numbers but after performing the experiment it was being found out that most of the alpha particles pass straight through. This observation clearly meant that most of the space inside an atom is empty which was contrary to that predicted in Thompson’s model. Hence, Ernest Rutherford got unexpected results from his experiment.
