Which of the following would be a reasonable estimate for the height of a skyscraper?
1 × 10^-8 feet 1 × 10^-3 feet
1 × 10^3 feet
1 × 10^8 feet

A reasonable estimate is 1 x 10^3 feet. By elimination, the first and second can't be since it will yield a negative answer and height can't be negative. Next, the fourth option will yield almost 1800 miles tall which is an impossible height. So the third is the reasonable estimate. Hope it helps.

B) as the temperature increases, the kinetic energy of the particles increases.|-/

Aliquid is an answer i hope this
