From the question we are told that
The efficiency of the carnot engine is
The efficiency of a heat engine is
The operating temperatures of the carnot engine is to
The rate at which the heat engine absorbs energy is
Generally the efficiency of the carnot engine is mathematically represented as
=>
=>
Generally the efficiency of the heat engine is
=>
Generally the efficiency of the heat engine is also mathematically represented as
Here W is the work done which is mathematically represented as
Here is the heat exhausted

Answer:
Explanation:
Mass of Earth,
Mass of Moon,
The distance between Earth and the Moon is,
We need to find the force of gravitational attraction between the Earth and the moon. The force of gravity is given by :
So, the required force is .
Answer:
A) Concentration of A left at equilibrium of we started the reaction with [A] = 2.00 M and [B] = 2.00 M is 0.55 M.
B) Final concentration of D at equilibrium if the initial concentrations are [A] = 1.00 M and [B] = 2.00 M is 0.90 M.
[D] = 0.90 M
Explanation:
With the first assumption that the volume of reacting mixture doesn't change throughout the reaction.
This allows us to use concentration in mol/L interchangeably with number of moles in stoichiometric calculations.
