What is the death rate of underwater welders?
The average death rate of welders who work under water is 20 deaths per year per 300 welders. The job is extremely dangerous because of the challenges of working under the water alongside large ships.
Why do object that under water look close than they actually are?
Light bends as it passes from the water to the air - this changes the perspective of where the object is.
What is the scientific explanation for the bends?
the explanation is that the bends are caused by nitrogen in the blood stream and the block up the blood way and causepain. to get rid of the bends you need to see a doctor IMMEDIATELY. TO PREVENT THE BENDS rise to the surface of the water every 15 minuets. the air will then clear you blood passage. Nitrogen in the bloodstream causes bends, which leads to blocking of the bloodstream causing pain
Why can you get the bends?
The reason you get the bends is because of the nitrogen inside the tank. When you are deep under water the pressure gets higher. If you stay at 20ft for 5 minutes this will release all the nitrogen at a proper rate. If you shoot to the top the nitrogen spews out too quickly which is bad so, when that happens you will get the bends.
What are causes for tsunamis?
What causes the tsunami is an earthquake under ground and it blows the water to land
Does a under water volcano cause a tsunami?
yes they do because it causes a earthquake under the water and that's how tsunamis happen
Why is it very difficult to spear a fish unless you are under water?
Because when light passes from water into are - it refracts or bends. This makes the fish appear to be in a different place to where it actually is. You can demonstrate the effect using a glass of water and a drinking straw. Half-fill a glass with water, then lower one end of a straw into it. You will see the straw 'bends' as it hits the water. It's the same effect in spearing fish.
How many earthquakes happen in water?
The plates under the ocean moves which causes the water to have shock waves.
Light bends when it travels through water?
true, it does bend when it travles through water.
Why does the water level rise after tsunami?
An under water earthquake precedes a tsunami. Earthquake causes seismic waves which set up the water in motion with a large force. This causes a tsunami.
