Chemical energy is the energy released or absorbed in a chemical reaction during the decomposition or formation of compounds
That's the definition but what was d? maybe I can help narrow it down
Answer:
Explanation:
The thermal efficiency of a Power cycle
where;
--- (1)
---- (2)
The coefficient of performance is:
let replace the value of in the above equation then;
The
On the other hand, the heat pump
By replacing equation (1) into the above equation; we have:
t
As we know that work done by external environment is given as
here we know that
P = 200 N/m^2
now we will have
so work done by external atmosphere will be 40 J
so correct answer will be
A. 40 joules
C.an equal and opposite reaction
Answer:
The acceleration increases because the mass decreases.
Explanation:
From Newton's second law, force equals mass times acceleration.
F = ma
Solving for acceleration:
a = F / m
F is constant. As the fuel runs out, m decreases. Therefore, a increases.
