Why would a scuba diver go underwater?
Becasue if a SCUBA diver didn't go underwater, they really wouldn't be a SCUBA diver. SCUBA stands for Self-Contained Underwater Breathing Apparatus.
What would happen if a scuba diver dived without a regulator?
Then he wouldn't be a scuba diver since he wouldn't have his breathing device.
How is the frog like a scuba diver?
Well, it needs oxygen like a human scuba diver but it lasts a pretty long time underwater just like a human would if he used an oxygen tank.
What are the examples of Pascal's principle?
scuba diving.... the diver would equalize the pressure between his ears and mouth..
Before a diver dives will he will take a deep breath or hyperventilate?
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
Why do scuba divers need to exhale when they ascend to the surface?
As the diver ascends to the surface the external pressure decreases. If the air in the lungs were not exhaled, the volume in the thorax would expand, and the diver's lungs would explode.
What are the scuba diver is 31 feet below the surface of the water she dives down an additional 15 feet how far would she have to rise to reach the surface of the water?
16 Feet
Who would use the scuba gear?
Scuba divers.
What would be a good comparison of the affect of a 2 knot current on a scuba diver compared to a wind current on land?
Currents have a disproportionately greater effect when pushing water against a scuba diver than wind does when pushing air against a person above the surface. This is for two reasons: firstly, water is much more dense; secondly, a diver swimming has less propulsion than a person walking (ie. you can walk faster and with less effort than you can swim). I am not aware of any scientific formulae comparing the two, but I would compare swimming into a two knot current wearing scuba gear as the rough equivalent to trying to walk into a windspeed of approximately 30 knots.
What would happen to a diver who does not exhale while surfacing from a 30 m dive?
A toxic condition called nitrogen narcosis affects scuba divers who venture to the depth of 30m. It can result in death!

Scuba diver or open water course which would you be better doing?
The name Open Water course is pretty much standardized in the industry for the beginning level course. But there are still some "lower level" courses (sometimes called a Scuba Diver course) in addition to the Open Water course. Just see which one give you more dives. You should get 4 to 5 scuba dives in your course with a possible skin dive which is often optional, but in general the Open Water course is considered the better and more complete course.
