The total force in each direction has to be the same.
The total force of the blue team is
(220 + 340 + 180 + 560) = 1,300 N
The three members of the red team add up to
(250 + 160 + 420) = 830 N
In order to exactly match the 1,300 N of the blue team,
the fourth red-team guy must contribute an additional
(1,300 - 830) = 470 N .
Answer:
a) 3.210J/K

c) -3.131J/K
d) O
Explanation:
The relationship between entropy and the energy transferred is applied.
Mathematically, dS = dQ/T
the steps are as shown in the attachment.
Today we can make observations that would lead us to the same conclusion as newton. If you throw a baseball in the air, it always comes back down. This is because of gravity. duh.
