Answer: Physiologic response to fear is very similar to that of PTSD and stress. Fear is accompanied by increased heart rate due to the release of adrenaline, sympathetic nervous system is aroused. The release of adrenaline also causes increased sweating, pulse and blood pressure. In line with this, the parasympathetic nervous system experiences reduced activity such as decrease in digestion.

Answer: Fur stuffed with feathers.
Explanation:
Ball games were popular throughout ancient history but also in the Middle Ages. Many of these games are the forerunners of today's American football and soccer. There are data on almost all continents on how peoples practiced some ball sports in antiquity. The game balls' look was not like today, it was mostly egg-shaped, and the materials for making it were different. The most common material for making the ball was leather, which was filled with feathers.
Net force = (mass) x (acceleration)
There are two forces acting on the barrel:
-- the force of gravity, downward;
-- the force of the rope, upward.
When these two forces are added together, their sum (the net force
on the barrel) causes the barrel to accelerate upward at 1.4 m/s² .
Net force = (Rope force) - (Grav force) = (mass) x (acceleration)
Grav force = 'weight' = (mass) x (grav) = (16 x 9.8) = 156.8 newtons
Net force = (mass x acceleration) = (16 x 1.4) = 22.4 newtons
Net force =
22.4 newtons = (Rope force) - (156.8 newtons)
Add 156.8 newtons to each side: Rope force = 22.4 + 156.8 = <em>179.2 newtons
