20. A box of length 22 cm and mass 100 g rests on a horizontal frictionless oor. A small bead of mass 10 g is placed at the centre of the bottom of she box. There is no friction between the bead and the bottom of the box. The bead is projected with a velocity 11 cm/s parallel to the length of the kox. If all the collisions are perfectly elastic, find displacement of the box in a time interval 60 s after the bead was projected. Ano:60 cm

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
