The rate in which a tissue compartment loads and unloads gas is called a half-time; the amount of time it takes the remaining space within the theoretical compartment to fill/empty - e.g. from 0% to 50% and then from 50% to 75% etc.

There are 6 half-times in every compartment before it is considered saturated or desaturated.

We have all the information we need to answer this one with ease. It tells us how much downward force the anchor has - 22 Kgs and how much upward force the displacement is causing - 18 litres, and which type of water the anchor lying in.

Since it's asking for an answer to be expressed as volume we must convert the weight from Kgs to litres, since this is seawater that will be 22/1.03 - the weight of the object divided by the weight of the water. That equals 21.36 litres.

That represents the total volume required to lift the anchor. Since I already have 18litres of displacement already assisting this, I have to subtract that from the total amount. 22.36-18=3.36 litres.

This is the Coriolis effect; an inertial force that acts upon the water and storms so they move clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere.
