<h2>
Answer: the falling time</h2>
Explanation:
When a body or object falls, basically two forces act on it:
1. The force of air friction, also called<em> </em><u><em>"drag force"</em></u>
:
(1)
Where:
is the drag coefficient
is the density of the fluid (air for example)
is the velocity
is the transversal area of the object
So, this force is proportional to the transversal area of the falling element and to the square of the velocity.
2. Its <u>weight </u>due to the gravity force
:
(2)
Where:
is the mass of the object
is the acceleration due gravity
So, at the moment <u>when the drag force equals the gravity force, the object will have its terminal velocity:</u>
(3)
(4)
(5) This is the terminal velocity
As we can see, there is no "falling time" in this equation.
Therefore, the terminal velocity is not dependent on the falling time.
Any type of physical act isn’t a emotional reaction. Things like crying or yelling or getting mad at yourself is emotional. Changes in your activity level, change in eating, sleeping, sense of humor. Increased uses in tobacco or drugs, when you’re becoming accident prone, when you’re not able to relax, when your heart rate increases, headaches, startled easily, when you’re tired all the time and sleep doesn’t help (fatigue). For women your period might change. When you get lower back pain, upset stomach, flare ups that are associated with allergies asthma or arthritis and if you get sick easier.

They may have a difficulty concentrating. You can look up so many ways that stress can affect a person physically
