The human lungs can function satisfactorily up to a limit where the pressure differ- ence between the outside and inside of the

lungs is one-twentieth of an atmosphere. If a diver uses a snorkel for breathing, how far below the water can she swim? Assume the diver is in salt water whose density is 1025 kg/m3.

Answer:

The correct answer is 0.53 meters.

Explanation:

The given density of water is 1025 kg/m^3

Gauge pressure, that is, (P2 - P2) = Po/19

Here Po = 1.013 * 10^5 Pa

= 1.0.13 * 10^5 Pa / 19 = 5331.58 Pa

The change in pressure associated with the depth is given by the formula:  

P2 -P1 = ρgh  

h = P2 - P1 / ρg

h = 5331.58 Pa / 1025 kg/m^3 * 9.8 m/s^2

h = 0.53 m

Thus, the driver can swim 0.53 meters below water.

Dialogue conversation between two friends on the negative effect of social media on teenager
dolphi86 [110]
To be honest, Niklesh, I hold a firm doubt that somebody will want to do this work for you unless they have been assigned it–especially since social media is so prevalent today.

If you disagree with the assignment and can veer off a little, I'd suggest writing a conversation about how responsible use of social media benefits teenagers and helps connect the world.

a few good points for this would be:

• Networking with people in higher places is especially important for entrepreneurship and job searching (SEE: LinkedIn)
• Social media helps bring people with similar interests from across the globe together
• Social media allows people to communicate experiences, events, and just communicate when physical interaction is difficult to attain
