Answer:
Statement 1 and statement 2 are correct and statement 2 is the correct explanation of statement 1
Explanation:
Both the velocity and kinetic energy of a gas molecule depends on its relative molecular mass according to Graham's law of diffusion in gases. Hence, the greater the relative molecular mass of the gas, the lesser its average velocity and kinetic energy.
Hence we can see that statement 2 vividly explains the postulation of statement 1 and makes the points more easily comprehensible.
A. <span>Standing is health-enhancing because it uses energy.
Because standing can burn a lot of calories.</span>
If i am reading this question right the answer should be the south pole
A = Delta v/Delta t
Delta v = 25 - 0 = 25
Delta t = 30
25/30 = 5/6 = 1.66 repeating
"<span>(2) They transfer energy" is the best option from the list regarding the </span>characteristics of both sound waves and <span>electromagnetic waves, but these energies are different. </span>
