<u>Answer: </u>
<em>Considering the II law of thermodynamics</em>
<em>From the figure</em>
<em>Out put of energy: </em>
Heat supplied from the source/ reservoir (Q₁) - Heat rejected to the surroundings from the system (Q) = Q₁ - Q₂. Also known as Net work done on the system.
<em>Input of energy: </em>
Amount of heat energy supplied to the system from the source (Q₁ ).
Efficiency (H.E) = η = Output÷ Input
η = (Q₁ - Q₂) ÷ Q₁
OR η = Wnet ÷ Q₁ ; since Wnet = (Q₁ - Q₂)
KE = 1/2 mv^2 is the relationship betwee mass and kinetic energy
Answer: informative array
Explanation:
"The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods."

Explanation:the both are telling us more about a gasket
Melting of ice caps ... causing them to shrink in coverage .. can result in ...
-- wet ground
-- more farming opportunities, but less skiing
-- higher sea level
-- coastal flooding
-- extinction of plant and animal species
-- more icebergs floating around
-- lower average albedo, higher solar absorption, widespread warming
