This question is a little vague. To answer in the simplest terms...swim to the surface at a rate of no more than one foot per second. After long dives or deep depths, divers should make a safety stop for several minutes before finally breaking the surface to be certain that the necessary amount of excess nitrogen has been expelled from the body.
you just kick up, its basically like swimming but you go up instead of froward
Many divers resurface by exhaling. They can also resurface by swimming back to the surface of the water when they are ready.
because bubbles of nitrogen that are abosrbed into the blood at high pressures but are normally insoluble start being released from the blood as the diver rises. If this happens to quickly bubbles in the blood form and the diver gets the bends
You can have your brake rotors resurface for approximately $20. The brake rotor thickness must meet minimum standards, in order for them to be resurfaced.
Divers wear tanks full of oxygen to help them breathe while they are under water. When the tanks start to get empty, they resurface.
you can resurface a strawberry with chocolate
they must come over the pressure
You must be at least 10 years old to enroll in a PADI junior open water diver course.
Dissolved nitrogen and nitrogen narcosis
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
NO NO !! You must remove the vinyl completely and then check what substrate you have. Concrete plaster or brick will be fine.
