Answer:
3.33, 4.84
Explanation:
A) Actual coefficient of performance can be calculated by the formula stated below
Actual COP = heat delivered/ work required
Actual COP = 2,000/600
Actual COP = 3.33
B) Th = High temperature = 80°C + 273 = 353K
Tl = Low temperature = 7°C + 273 = 280K
The theoretical maximum coefficient of performance can ve calculated by the formula
Theoretical COP = Th/(Th-Tl)
Theoretical COP = 353/(353-280)
Theoretical COP = 353/73
Theoretical COP = 4.84
Answer:
yes
Explanation:
I think so because it not mention in the law
Answer:
-3.4 eV ()
Explanation:
In a hydrogen atom, the energy of an electron is given by:
where
n is the principal quantum number
For an electron in the 2s orbital,
n = 2
So substituting this value into the formula, we find
And converting this into Joules, we have
Einstein's Big Idea homepage. E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
450 J / 3 s = 150 J/s = 150 watts.
