[A] : Tail wagging dance is performed for short distances . It conveys both the distance and speed of the scout bees . [R] : Foraging bees keep touching the scout bees through dance to get the information mainly by olfactory stimulation .

A small ball of mass m is attached to the middle of a tightly stretched perfectly flexible wire AB of length 2 l (figure ). The ball is given a small lateral displacement in horizontal direction and released. The initial tension (T) in the wire is high and change in it due to small lateral displacement of the ball can be neglected. Prove that the ball will perform simple harmonic motion, and calculate the period. If there is a device which can change the tension in the wire at will , how will the time period change if tension in the wire is increased

Imagine that you drop a ball. It bounces a few times and then it stops. Your friend says that the energy that the ball had is gone Where did the energy go ? Evaluate your friends statement based on energy conservation.

A ball of mass m is projected from ground making an angle q to the horizontal. There is a horizontal wind blowing in the direction of motion of the ball. Due to wind the ball experiences a constant horizontal force of (mg)/(sqrt(3)) in direction of its motion. Find theta for which the horizontal range of the ball will be maximum.

Five Styrofoam balls are suspended from insulating threads. Several experiments are performed on the balls and the following observations are made: (i) Ball A repels C and attracts B. (ii) Ball D attracts B and has no effect on E. (iii) A negatively charged rod attracts both A and E. An electrically neutral Styrofoam ball gets attracted if placed nearby a charged body due to induced charge. What are the charges, if any, on each ball A,B,C,D, and E?

A batsman hits a cricket ball which then rolls on a level ground . After covering a short distance, the ball comes to rest, The ball slows to a stop because
