Answer: The particles of a solid are [generally] closest together while those of a gas are farthest apart
Explanation:
From the equation;
a= -1÷2gT2
a= -5×3(3)
a= -45m/s
it will drop about -45m/s2.
Solid phase. The atoms are tightly packed and vibrate.
Answer:
About 2.19 seconds
Explanation:

Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:

Hope this helps!
Answer:
1.8m
Explanation:
Let the Elastics of the steel ASTM-36 
The strain of the bar when subjected to 150 MPa is

Therefore, if the bar elongates by 1.35 mm, then the original length L would be:

or 1.8m
