Explanation:
In periodic motion, amplitude is half the distance between the minimum and the maximum.
A = (max - min) / 2
Answer:
(1) The maximum air temperature is 1383.002 K
(2) The rate of heat addition is 215.5 kW
Explanation:
T₁ = 17 + 273.15 = 290.15
T₂ = 290.15 × 3.17767 = 922.00139
Therefore,
T₃ = T₂×1.5 = 922.00139 × 1.5 = 1383.002 K
The maximum air temperature = T₃ = 1383.002 K
(2)
Therefore;
Q₁ = 1.005(1383.002 - 922.00139) = 463.306 kJ/jg
Heat rejected per kilogram is given by the following relation;
= 0.718×(511.859 - 290.15) = 159.187 kJ/kg
The efficiency is given by the following relation;
Where:
β = Cut off ratio
Plugging in the values, we get;
Therefore;
Heat supplied = 
Therefore, heat supplied = 215491.064 W
Heat supplied ≈ 215.5 kW
The rate of heat addition = 215.5 kW.

Essential Knowledge
It is essential that the student be able to distinguish between specialized structures that allow protists and fungi to obtain energy and explore their environment.
Protists
Protists are organisms that are classified into the Kingdom Protista. Although there is a lot of variety within the protists, they do share some common characteristics.
● Protists are usually single celled organisms.
● Live in moist environments.
● Vary in the ways they move and obtain energy.
Protists obtain their energy in several ways.
● Animal-like protists ingest or absorb food after capturing or trapping it.
● Plant-like protists produce food through photosynthesis.
● Fungus-like protists obtain their food by external digestion either as decomposers or as parasites.
● Some protists have both autotrophic and heterotrophic characteristi
Adhesive.
Adhesive is the force of attraction between molecules of different kind. Liquid flows upward the wick because the adhesive force between the wick and the liquid is higher than cohesive forces in the liquid.
When the adhesive force between the wick and the liquid is high we have capillarity taking place. This cause the liquid to move up the wick.
