Question

The circumference of Earth at the equator is 24,900 miles. Calculate how fast someone at the equator is rotating in miles per hour. If the rotational speed of Earth were to slow down, how might this impact daytime highs and nighttime lows

Answer 1

Answer:

speed = 1037.5 miles per hour

day and night will be more longer

and in day temperature will be increase

and in night low temperature will be low

Explanation:

given data

circumference of Earth = 24,900 miles

to find out

how fast someone at the equator is rotating in miles per hour

solution

we know that speed is

speed = $\frac{distance}{time}$

we assume time for one rotation is 23:56:04 that is equal to 23.934 hours per day and we consider around 24 hours per day

so

from equation 1

speed = $\frac{24900}{24}$

speed = 1037.5 miles per hour

and if the rotational speed of Earth were to slow down then rotation time will be longer than 24 hours per day

so day and night will be more longer

and in day temperature will be increase

and in night low temperature will be low
