Calculate the acceleration of the object in free fall (picture shown above)

Answers

Answer 1

Answer:

Estimate slope= acceleration of -18.75 m/s^2

Explanation:

In the velocity vs time graph, acceleration is the slope

Let's take two points from the line and find the slope

(0,0) (0.8, -15)

slope = -15-0/ 0.8-0 = -18.75 m/s^2

why is gas matter even though we cannot see it?

Answers

Answer:

There is matter in gas but due to the high intermolecular forces, all the molecules of gas are far apart

Since the size of a molecule is almost negligible to the human eye, we cannot see the gas molecules and hence, gas is invisible to the naked eye

If you compress a gas against the intermolecular forces, the gas will turn into a liquid

Chinese scholars have uncovered written documents from this period that show an early form of present-day Chinese characters. The writing looked more like pictures than the standard characters of today. It consisted of phonetic signs, or signs that mimic human speech. During the Shang period, more than 3,000 characters were in use. Scholars have deciphered about 1,000 of those characters. Considering that modern Chinese uses about 3,500 characters consistently, the ancient Chinese created a written language that has remained relevant and evolved over time. find the difference between 20 and the sum of 10 and 3 Solve for this and get 12 points Find the difference of 3 and -2 (HURRY I NEED HELP NOW ILL GIVE YOU BRILLIANT).
