The variety of species in an ecosystem is known as biodiversity.
Answer:
Work W=4.16 Btu
Heat transfer Q=14.56 Btu
Explanation:
To calculate the work W we will use the given pressure p=30 psia and volume V₁=0.75 ft³ V₂=2.V₁
Now for heat transfer
The last equation we will rewrite using ideal gas law to calculate heat transfer
Answer:
the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.
Explanation:
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.
