What is the net force acting on a falling object when it reaches terminal velocity?

An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.

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.
When an object reaches terminal velocity what is the net force acting on the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
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.
Why a larger rain drop falls faster than a small rain drop?
Considering the rain droplets as spherical body. We have two forces acting on the rain drop when it is falling through the sky, namely the resistance force due to friction(drag force)upwards and its weight downwards. Th rain drop falling from such distance attain a terminal velocity while falling i.e their speed becomes constant after sometime. This happens when the drag force equals the weight of drop,, this happens because drag force increases with velocity of the drop. Drag force= .5*rho*v2*A(frontal area)*Cd(coefficient of drag) Weight=m*g=rho*volume of spherical drop=rho*4/3*r3. When we equalize it, we get the Terminal Velocity(v) varying directly as sqr of r(radius of drop) So larger drop means, larger terminal velocity and hence less time taken for falling. So larger rain drop falls faster.
When a falling object reaches terminal velocity the net force is acting on its?
Zero.
When a falling object reaches a terminal velocity the net force acting on it's?
Zero.
What is net force acting on a falling object when it reaches terminal velocity?
The net force is zero.
What is the net force acting on a falling oject when it reaches it terminal velocity?
Air resistance equals the pull of gravity, so essentially zero.
When the only force acting on a falling object is gravity the objects is said to be?
= Terminal velocity =
The drag force acting on a falling sky diver is also known as?
Terminal Velocity.
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.
What is the net force acting when it reaches terminal velocity?
Terminal velocity means that the velocity no longer changes; therefore (by Newton's Second Law), since the acceleration is zero, the force must also be zero.
When an object reaches terminal velocity what is the net force acting on the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
Is it false that balance forces are equal forces acting on an object in opposite directions?
Is the greatest velocity a falling object reaches is called its momentum
What is the net force acting on a falling object when it reachs termin?
"Terminal velocity" means that it no longer accelerates; and that, in turn, means that the net force must be zero.
Does a larger sphere have a higher terminal velocity?
No it would have a lower terminal velocity as there would be more air resistance acting upon it
