Answer:
I believe the answer is A
Explanation:
I hope this helps :)
The best and most correct answer among the choices provided by your question is the fourth choice which is "<span>Heat moves through conduction, convection, and radiation."
</span>Heat transfer<span> is the exchange of thermal energy between physical systems. The rate of </span>heat transfer<span> is dependent on the temperatures of the systems and the properties of the intervening medium through which the</span>heat<span> is </span>transferred<span>. The three fundamental modes of </span>heat transfer<span> are conduction, convection and radiation.</span>

Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
Answer:
creat and trough are the parts of transverse wave
The rate of effusion of H₂ : 7.2 x 10⁻² m/s
<h3>Further explanation </h3>
Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
or
MW₁ O₂ = 32 g/mol
MW₂ H₂ = 2 g/mol
