How great is the air resistance that acts on a 10-N sack that falls in air at constant velocity?

constant velocity= no acceleration and no net force
Assuming that there are no other forces acting on the sack (besides gravity and air resistance) this means that the force of air friction equals the weight of the object, so that the air resistance is 10N acting upward exactly balancing the force of gravity acting down

Which falls faster an orange or a cannonball?
The cannonball will, for its mass, experience proportionately less air resistance than the orange since its density is some 17 times greater than the orange's. Since the air resistance will eventually balance the acceleration due to gravity, the cannonball will achieve a higher terminal velocity than the orange if both are dropped from a great height. For short drops of a few meters, the difference in the effect of air resistance will be hardly noticeable and both will appear to fall at the same speed.
How does a stream's gradient affect its velocity?
the difference in velocity is mostly due to the great efficiency of the large downstream channel.
What properties of space determine the velocity of light?
The velocity of light and all electromagnetic radiation is determined by two properties of space. One is the electrical property which is permittivity and the other is the magnetic property which is permeability. Their values were determined more than 150 years ago by the great scientist Jame Clerk Maxwell. They are not constant in value, but vary based on the material in which they are located. In most cases they diminish the velocity, but in a few they increase it. If the value of either or both of these properties can be modified, then the velocity of light can also be modified.
Define terminal velocity?
I used to do a bit of parachuting back in the 70s and terminal velocity was always reckoned to be about 120 mph (200 kph) achieved after about 12 seconds in free fall. But different objects will have different TVs, depending upon how aerodynamic they are. In physics, When an object is in a freefall, and it reaches its terminal speed, there is no net force, and so its acceleration is zero. Going down, the direction of the air resistance is downwards, whereas that of the weight is upwards. Going up, air resistance R and weight W are in the same direction. i.e. downwards. By F=ma, When an object is thrown vertically upwards, at the instant its speed equals this terminal speed on the way up, the magnitude of its acceleration is 20ms-2. the direction is downwards. then by v = u + at, you can easily calculate the terminal velocity in many different cases.
What is the difference between resistance and impotence?
There is a great difference between resistance and impotence. Impotence suggests helplessness but it can take great strength and ability to resist. The French Resistance during WW II did much damage to the Germans. They were an inferior position but definitely not helpless.
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
What will happen if object falls from great height through air of uniform density?
It will fall faster and faster for a while - until it eventually reaches a "terminal speed", at which air resistance and gravity are in balance. After that, it will continue falling at a constant speed.
Does the speed of a ball increase or decrease after it hits the ground?
Once a ball has fallen a distance through the air, and it contacts the ground, its speed will rapidly decrease until it has stopped moving. The acceleration experienced by the ball is so great that it seems to stop instantly. Most likely, it will bounce back up, and then repeat this cycle a few times before coming to rest.
How can an object have balanced forces and still move?
If an object is at rest it takes an unbalanced force to get it moving. Also if an object is moving it takes an unbalanced force to stop it. So if an object is in motion, because of some unbalanced force and then, while moving, another force comes in to make the forces balanced this will not be enough to stop it, just keep it from accelerating. This happens when objects are dropped from a great height. At first the force of gravity causes it to pick up velocity (accelerate) as it falls. But as it picks up speed the force of air resistance gets larger and larger. Pretty soon the downward force of gravity is just balanced by the upward force of air resistance. The object continues to fall , but now at constant velocity.
Babies have been heard to survive from falls from great heights what is the terminal velocity of a baby at sea level?
I don't know about a child, but terminal velocity for a skydiver is roughly 120 miles per hour, depending on their position in which they fall.
