Answer:c>a>b
Explanation:
Given
All the engine extracts same amount of heat(Q) from High-temperature reservoir
For a) 400 and 500 K
For b)500 K and 600K
For c) 400 K and 600 K
So c will give the highest amount of work
c>a>b
It is the solar system because the planets are in it
Answer:
16 pigs
Explanation:
Let the horses be H.
Let the pigs be P
Let the total number of animals be x.
Given the following data;
Ratio of P to H = 2:3 = 2 + 3 = 5
Number of horses = 24
To find the number of pigs;
First of all, we would determine the total number of animals x.
From the ratio of horse, H:
3/5 * x = 24
Cross-multiplying, we have;
3x = 120
x = 120/3 = 40
Next, we find the number of pigs;
Pigs = 2/5 * 40
Pigs = 80/5 = 16 pigs
C. Oxygen has a different attraction for electrons in H2O than in CO2
the covalent bond between Hydrogen-Oxygen and Carbon-Oxygen is different because the difference of electronegativity (the tendency of an atom to attract a shared pair of electrons towards itself) between Hydrogen and Oxygen is a lot higher than the difference of electronegativity between Carbon and Oxygen. This difference in electronegativity results in separation of partial electric charge creating polar bonds and giving the molecule a polarity.
