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 the gas is heated, the molecules move faster and spread out from each other" is the one among the following choices that <span>best explains why a tank of compressed gas can explode if it is heated. The correct option among all the options that are given in the question is the second option or option "B".</span>
Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube
He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field
so here we will use the deflection as following
let say it passes the field of length "L"
so here we have

now in the same time if it deflect by some distance


now by solving this equation we can find e/m ratio
so here correct answer will be
the electron's charge-to-mass ratio
Some ice has more salt then the other causing it to float up
No, light does not have mass because a photon does not way anything.
