Since Jason plays a lot of sports <em>(D)</em>, there's a good chance that he has developed a greater-than-average lung capacity. This is a good thing.
The ideal gas law allows a scientist to calculate the number of moles that the other gas laws do not. The ideal gas law is given as
P V = n RT
rearranging the equation by dividing both side by "RT", we get
PV/(RT) = nRT/(RT)
n = PV/(RT)
inserting the values of pressure, volume and temperature, we get number of moles.
Treatment water from the plant would affects the communities present in the downstream of the river.
Answer: Option (a)
<u>Explanation:</u>
Wastewater treatment plant is a process used to treat the water that flows from the rivers, streams, and lakes.This plant removes the dust, sand, sediments present in the river water.
When this treated water is released into the downriver stream, it affects the health of aquatic organisms present in that stream.Use of chemicals in treating the wastewater may cause genetic problems to the communities present in that region.
It also causes air pollution and more energy is needed for the treatment process and thus affects the ecosystem.
Efficiency of a machine = (useful output energy) / (total input energy)
Efficiency = (500 J output work) / (Carlotta's 2,000 J input work)
Efficiency = (500 J) / (2,000 J)
Efficiency = 0.25
<em>Efficiency = 25%</em>
