: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects
The Moon's diameter is 1/110 the distance between Earth and the Moon. ... The sun's diameter is 1/110 the distance between Earth and the Sun.
Here are the choices.
A. 200 m
<span>B. 31.25 m </span>
<span>C. 0.2 m </span>
<span>D. 5 m
</span>Pa = N/m²
<span>m² = N/Pa </span>
<span>12.5 kPa = 12500 Pa </span>
<span>m² = N/Pa </span>
<span>m² = 2500 / 12500 </span>
<span>m² = 0.2 </span>
<span>C. 0.2 m²
</span>
So the correct answer is 0.2m^2
