Answer:
PE = mgh = 13.6(9.81)(1.25) = 166.77 ≈ 167 J
Explanation:
Elements with low specific heat values tends to absorb heat energy lesser which means it will heat up faster. Having low specific heat values means it can have rapid changes in temperature. Metals generally have a low specific heat capacity, that's why their temperature can change so quickly.
At tne equator, daylight is always 12 hours.
<span>The further away from the equator, the length of daylight in summer increases, until at latitudes higher than the arctic circle it will be 24 hours at the summer solstice.</span>
