Answer:
B. The dust and ash would block sunlight, triggering climate change.
Explanation:
If such an event as a nuclear war should cause large amount of dust and ash in the atmosphere, this will trigger climate change.
Dust and ash can lead to severe consequences on the global climatic pattern.
- The rising dust and ash will block out sunlight and electromagnetic radiation from reaching the earth surface.
- The earth will become abnormally cold as the source of the earth's heat is cut off.
- This will lead to freezing of water bodies and more cold-inclined world climate.
Answer:
The volume is decreasing at 160 cm³/min
Explanation:
Given;
Boyle's law, PV = C
where;
P is pressure of the gas
V is volume of the gas
C is constant
Differentiate this equation using product rule:
Given;
(increasing pressure rate of the gas) = 40 kPa/min
V (volume of the gas) = 600 cm³
P (pressure of the gas) = 150 kPa
Substitute in these values in the differential equation above and calculate the rate at which the volume is decreasing ( );
(600 x 40) + (150 x ) = 0
Therefore, the volume is decreasing at 160 cm³/min
