An air compressor is a device that pumps air particles into a tank. a particular air compressor adds air particles to its tank until the particle density of the inside air is 20 times that of the outside air. if the temperature inside the tank is the same as that outside, how does the pressure inside the tank compare to the pressure outside? assume atmospheric pressure equal to 100,000 pa.

An object weigh 40n in air ,weigh 20n when submerged in water,and 30n when submerged in a liquid of unknown liquid density.what is the density of unknown of liquid?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Explain what will happen if decomposers were apsent from a forest ecoysystem.
