A scuba diver swims deeper and deeper into the ocean. What happens to the nitrogen in her blood as she goes deeper

it compresses under the pressure.

Explanation:

when she comes up, it will re-expand as pressure goes down- this is why they have to be very careful how fast they come back up.

If a diver goes through too great of pressure change too quickly, their body cannot eliminate all of the expanding nitrogen and the excess nitrogen forms bubbles in their tissues and blood. These nitrogen bubbles can cause decompression sickness (DCS) by blocking blood flow to various parts of the body, causing strokes, paralysis, and other life-threatening problems.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

the correct answer is:

a. formation of precipitation
