Weightlessness in space: Space travellers as well as objects in the spacecraft appear to be floating. Why does this happen? Though the spacecradft is at a height from the surface of the earth the value of g there is not zero. In the space station the value of g is only 11% less than its value on the surface of the earth. Thus, the height of a spacecraft is not the reason for their weightlessness. Their weightlessness is caused by their being in the state of free fall. Though the spacecraft is not falling on the earth because of its velocity along the orbit, the only force acting on it is the gravitational force of the earth and therefore it is in a free fall state. As the velocity of free fall does not depend on the properties of an object, the velocity of free falls is the same for the spacecraft, the travellers and the objects in the craft. Thus, if a traveller releases an object from her hand, it will remain stationary with respect to her and will appear to be weightless. If a traveller releases an object from her hand in the spacecraft, what will happen?

Three sources of sound S_1, S_2 and S_3 of equal intensity are placed in a straight line with S_1S_2=S_2=S_3 . At a point P. far away from the sources, the wave coming from S_2 si 120^@ ahead in phase of that from S_1 . Also, the wave coming from S_3 is 120^@ ahead of that from S_2 . What would be the resultant intensity of sound at P ?
