make sure you take lots of socks and pants. you might want to take some medicine if you get sick and take a good pair of gloves. Take a bunch of warm clothes and take chains for your tires. lastly dont eat yellow snow! lol

Question by David O: When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur?
If the force on the tympanic membrane (eardrum) increases by about 1.50 Nabove the force from atmospheric pressure, the membrane can be damaged. When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur? The eardrum is typically 8.20 mm in diameter. Take the density of seawater to be equal 1.03\times 10^3 kg/m^3.

I tried to work out the length of a column of sea-water that is 8.2mm diameter and has a weight (force = mass x acceleration due to gravity) of 1.5 newtons.

The calculation came to 2.81m. That sounds about right, eh?

Working:

1. volume of a cylinder = (area of circle) x (length of cylinder).

2. area of a circle = pi x radius squared

3. diameter = 2 x radius

4. 1 meter = 1000 mm (8.2mm = .0082m)

5. mass of a solid = volume x density

6. force = mass x acceleration (due to gravity)

So:

Force = ( volume of column x density of sea water ) x g
1.5 = (pi x .0082/2 ^ 2) x depth x 1.03 x 10^3 x 9.81
1.5 = 0.533 x depth

depth = 2.81m

Question by bpsdepp: What could I do to work towards being a scuba diving instrustor?
I’m thirteen now, and I want to be a marine biologist and teach scuba diving in my spare time. I’m certified now with NAUI diving. What can I do to work towards being a scuba instructor?

There’s nothing to do but get certified when you are old enough. It never hurts to have as much experience as you can about your area of study.

You can subscribe to Sport Diver, the official magazine of the PADI Diving Society, and get more familiar with equipment and marine species. You can learn as much as possible about safety from http://www.diversalertnetwork.org. You can volunteer for the Surfrider Foundation or Oceana and do some beach clean up. In a few years you can become a certified lifeguard through the American Red Cross.
