Spheres A and B of equal radius and of masses 2 m and m, respectively, are moving towards each other and strike directly. The speeds of A and B before the collision are 3u and u, respectively. The collision is such that B experiences an impulse of 4mcu, where c is constant.
What is the coefficient of restitution?

Two long, parallel, horizontal rails, distance d apart and each having a resistance 
per unit length are joined at one end by a resistance R. A perfectly conducting rod MN of mass m is free to slide along the rails without friction (see the figure). There is a uniform magnetic field of induction B normal to the plane of the paper and directed into the paper. A variable force F is applied to the rod MN such that as the rod moves, constant current flows through R.
The magnitude of the emf induced in the loop is

sulphuric acid. The unreacted acid required 20 ml of 
sodium hydroxide for complete neutralisation. The percentage of nitrogen in the compound is
Which of the following statements is false for the reaction H2 + Br2 
2HBr?
The rate law is 
= k[H2][Br2]½ .
2HBr is a bi-molecular reaction, hence the molecularity is 2.
The compound [Co(H2O)6]2+, having three unpaired electrons, shows the experimental magnetic moment of 4.40 BM, while the theoretical calculated value is 3.87 BM. This is because of
Directions: In the given question, the first and the last parts of the paragraph are numbered 1 and 6. The rest of the paragraph is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Find out the correct combination.
1. Our pleasures should be healthy so that they can impart a sense of well-being.
P. This applies very much to the passion for sports.
Q. Some people become slaves to an enthusiasm and regard it as their real and only pleasure in life.
R. It is quite possible that indulging in this passion is doing them great harm.
S. Modern sports have become so exaggerated that they can damage and sometimes destroy one's health.
6. An enthusiasm for violent sports may well dig an early grave for the participant.

A. Even in the depths of Japan's late-1990s recession, the country was still home to industrial world leaders and to some of the most respected brands in the global market.
B. They may well have done so as a consequence of government bullying to ensure that resources were poured into research and development but the results speak for themselves.
C. The Japanese economic lift-off did not come when companies were busy trying to make cheaper cars and cheaper electronic goods but when they started making products that were better than anything else in the market.
D. Japanese companies and the larger Korean companies are much more like Western organisations in terms of the resources they devote to business development.
