An inflatable raft (unoccupied) floats down a river at an approximately constant speed of 5.3 m/s. A child on a bridge, 60 m abo
ve the river, sees the raft in the river below and attempts to drop a small stone onto the raft. The child releases the stone from rest. In order for the stone to hit the raft, what must be the horizontal distance between the raft and the bridge when the child releases the stone?
If the temperature after mixing is higher than the temperature before mixing, It means that the forces acting between A and B molecules have increased (which is the new intermolecular forces).
There will be increase in the energy (brought temperature increase)required to break the old forces of attraction within each liquid molecules.
