8. a text book has a mass of 22 lbs, the book is 8 inches by 15 inches by 11.77 inches. what is
the density of the textbook using the values given?
fles $125.00

0.156 lb / in^3

Explanation:

Density = Mass / Volume

Here you already have the mass: 22 lbs

You dont have the volume but you have the dimensions.

The volume is:

V = 8 * 15 * 11.77 = 1412.4 in^3

Density = 22 / 1412.4 = 0.156 lb/in^3

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
