Yes!!! We can hear the engine of a boat in the water because water particles pass vibrations more quickly than the air particles

they get the bends
The record depth for a scuba diver is 313 meters. That is probably about the limit before pressure changes when surfacing would prove fatal. A diver could probably go deeper without being killed but wouldn't get to the surface again alive.
It is a visual reference as to where the clear water is. Otherwise it is difficult to know how close to the surface the diver is.
someone who cheats by pretending they have been fouled ...and they are termed a ''diver'' ..eg. Francis Lee who played for Manchester City in 60's & 70's was a diver !

There are two types of diver down flags - the diver down flag and the alpha flag. The red diver down flag is used when divers are in the water to alert boats to the possibility of divers near the surface, and the blue alpha flag is flown by a boat whenever the mobility of the vessel is restricted.

Hence the diver must spin faster when moment of inertia become smaller to conserve angular momentum. In this way the diver can make more somersaults before entering the water. Related To Chapter CIRCULAR MOTION
Have a decent amount of weights, or dump the air from the vest. Vice versa for staying on the surface.
