The problem is missing some parts but nevertheless here is
the answer:
Given:
1.7 m long barbell with 23 kg weight on the left and 34 in
the right end.
Solution:
Calculating from the left side:
Center of gravity = ΣM/ΣW = [23*0 + 9*(1.7/2) + 34*1.7]/[23+9+34]
Center of gravity = .992 m from the left end
Questions that can be answered by doing the experiment and making observations scientifically:
1). How long will it take to perform the complete experiment ?
2). Will it be daytime or night-time when the experiment begins ?
3). What will be the range of outdoor temperatures during the experiment ?
4). How many times will progress of the experiment be suspended in order to take phone calls ?
The correct answer would be 2: they transfer energy.
The state of matter that the particles move independently of one another with very little attraction is, I believe, gas
OK.
You're sitting in a soft comfy chair, reading a book in your lap.
The book stays put, and you eventually start to get sleepy, because
there's almost no acceleration happening.
The chair you're sitting in is seat #27B in a huge jet taking you to visit
your grandparents who live a thousand miles away.
The airplane is maybe 7 miles up, passing over the ground at nearly
500 miles per hour, flying straight, level, and fast !
