When a skydiver jumps out of an airplane there are two forces acting on her gravity and air resistance After falling for a few seconds the forces due to gravity and air resistance balance each other?

Your question is slightly confusing as you seem to have answered it yourself.
A little extra though, the speed at which the skydiver is now travelling is called terminal velocity and it is the fastest an object can travel with only gravity + air resistance acting on it as forces. Due to differing air resistances everything has its own unique terminal velocity and it is possible to alter it, this is the principle behind a parachute.

Greatest velocity a falling object reaches?
On any planet with an atmosphere, gravity is counteracted by the force of air friction with the object that is falling. This is known as terminal velocity - the point at which the forces of air resistance and gravity balance.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
Does air resistance increase or decrease the acceleration of a falling leaf from a tree?
Air resistance decreases acceleration of falling objects
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
How does an open parachute increase the air resistance of a falling skydiver?
by increasing surface area
How does a open parachute increase the air resistance of a falling skydiver?
by increasing surface area
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute.?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.

Is it true that the steady speed reached by a skydiver is called the terminal velocity?
Yes. Not just a skydiver; anything that falls long enough will eventually reach "terminal velocity", which means that it will continue falling at a constant speed, because the force of gravity and the force of air resistance are in balance.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.
A skydiver of mass 100 kg experiences air resistance while falling How fast is the skydiver being accelerated at?
Less than 9.8 meters (32.2 feet) per second2.That would be his acceleration ... and also the acceleration of the feather falling next to him ... if there wereno air at all.
How is air resistance used in a sentence?
air pressure is when air gets pressed down
Can you think of a situation where it is necessary to increase air resistance on a falling object how is it done?
Yes - falling out of an airplane. Use a parachute.
what force is increased after the skydiver open parachute?
To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.
Does air resistance affect a quarter falling?
Absolutely,Although the effect will be minimal if you drop the quarter from waist height.If you drop it from an airplane, it might even reach terminal velocity where the air resistance would counteract and balance the acceleration due to gravity.
What force or forces would be acting upon a falling airplane?
gravity wind resistance weight
