A falling skydiver of mass of 100 kg experiences 500 N air resistance The acceleration on the skydiver is what?

The first thing to do is to determine what forces are acting on the skydiver.
The force of gravity is pulling the skydiver downward, and can be described using Newton's 2nd Law:
F = ma
where F is the force, m is the mass, and a is the acceleration.
In this case, the acceleration is in the negative downward direction, and it is equal to the acceleration due to gravity,g, or 9.8 m/s2. So:
Fg = m(-g)
Fg = (100 kg)(-9.8 m/s2)
Fg = -980 N
The air is resisting her fall, so there is a force pushing upwards. Let's call it Fa, and it is given as 500 N. So:
Fa = 500 N
Nothing else is touching the skydiver, so there are no other forces acting on her.
To determine the acceleration, use the net force equation:
Fnet = ma
where Fnet is all the forces acting on the object.
Fnet = ma
Fg + Fa = ma
-980 N + 500 N = (100 kg)a
-480 N = (100 kg)a
(-480 N) / (100kg) = a
-4.80 m/s2 = a

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 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.
What happens to a falling object when the force of gravity equals to the force of air resistance?
the object will floatit shows increasing acceleration
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 does an 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.

Does air resistance increase or decrease the acceleration of a falling obect?
Well, the more the air resistance, the lower the acceleration.
What is the skydiver acceleration?
Upon leaving the aircraft, a skydiver rapidly reaches something called terminal velocity. This is where the resistance of the air matches the mass of the skydiver. At this speed, the skydiver maintains a relatively constant speed. Typically this is around 120mph in a flat body position and takes approximately 10 seconds to reach. For more questions about skydiving, see the attached link.
How does air resistance affect the acceleration of a falling abject?
Air resistance creates friction and slows a falling object.
A body falling freely from a height towared the earth moves with uniform?
... accelerates at approx 9.81 metres per second squared and experiences weightlessness. Friction with the air prevents continuous acceleration and the falling body reaches a maximum velocity called the terminal velocity.
How air resistance affect the acceleration of falling objects?
Air resistance causes friction and slows an object.
