(i) A child stands at the centre of turntable with his two arms out stretched. The turntable is set rotating with an angular speed of 40 rpm. How much is the angular speed of the child if he folds his hands back and thereby reduces his moment of inertia to (2)/(3) times the initial value ? Assume that the turntable rotates without friction (ii) Show that the child's new kinetic energy of rotation is more than the initial kinetic energy of rotation. How do you account for this increase in kinetic energy ?

Read the following information carefully to answer the given questions : XYZ Ltd. presently has three Accounts Assistants —A, B and C- and five Accounts Officers —D, E, F, G and H. Its management is planning to open a new office in another city using three Accounts Officers and two Accounts Assistants from its present staff. The following guidelines have been established to set up the new office. (i) A and C are constantly finding faults with each other and should not be sent as members of the same team. (ii) C and E function well alone but not as a team. They should not be sent as members of the same team. (iii) D and G do not enjoy good relations. They should not be sent as members of the same team. (iv) Since D and F have been competing for a promotion, they should not be sent as members of the same team. If D goes to the new office, then which of the following is/are correct? 1. C cannot go. 2. A cannot go. 3. H must also go.

When two sets of progressive wave trains of the same type, having same amplitude an same time period, travelling with same speed along the same straight line in opposite directions superimpose, a new set of waves are formed. These are called stationary waves or standing waves. The resultant waves do not propagate in any direction, nor there is any transfer of energy in the medium. Read the above passage and answer the following questions: (i) Stationary waves are characterised by nodes and antinodes. What are these points ? (ii) What is the total energy associated with a stationary wave ? What values of life do you learn from this ?
