How does the shape of a parachute affect how long it stays in the air?

Hey'
I just did an experiment for grade 11 physics that i designed where i investigated the shape and size of the parachute. The shape of the parachute doesn't effect how long it stays in the air much. The main thing that the shape effects is the stability and the less stable the parachute the faster the person will fall.
That is why parachutes are in that banana rectangle shape so that there is more stability to glide through the air, like a bird. As the shape changes how much drag there is. Circles are pure drag and take the longest to fall.

Does the size of a parachute affect how long it will float in the air?
yes it does
How does the size of the parachute affect the time it takes for the parachute to reach the ground?
It affects the time taken to reach the ground because the larger the area of the parachute the slower its velocity will be and consequently changes how long it takes to reach the ground. The larger parachutes will obtain far more air then smaller parachutes and have more air resistance and drag force.
Would a parachute be balanced when it falls?
As long as it is not accelerating (going faster and faster, or slower and slower), the forces on the parachute are balanced. Initially, the parachute will accelerate - in this case the forces are unbalanced. It will continue accelerating, until the force of gravitation is balanced by the force of resistance.
Does light accelerate?
No. As long as it stays in the same material, its speed is constant.

How does protein confirmation affect its function?
The shape, conformation, affect its function by determining what the shape is some proteins are long and fibrous : those form hair and form blood clots ... Some are globular and can function as enzymes which transport oxygen. The shape of a protein affects the function !
How long the string be on a parachute?
The 'best' length for a parachute string depends on what the parachute is for and the rest of the design. If a parachute's strings are too short, the whole parachute could collapse. If the parachute's strings are too long, there may be some wobbling and bungeeing about, more twisting of the strings, etc. Parachutes for heavy things (like spacecraft) tend to have longer strings than parachutes for people, since they're less affected by this instability.

yes, if your metabolism is fast and you are skinny THC will stay in your system as short as 1 day, as long as you drink lots and lots of water(;
