it's because of the ratio of the weight of the air in the balloon to the air outside the balloon
As long as the mass on the end is much greater than the mass of the string it's hanging from, the mass has no effect at all on the speed or the period.
An object's speed is (distance it travels) divided by (time to cover the distance). The object's mass doesn't matter at all.
The car's mass should have no effect on that speed.
Distance.

Momentum. Distance divided by time is speed. Mass times speed is momentum.
Gravitational force depends only on an object's mass and its distance from the center of the earth. Its speed has no effect on the gravitational force.
No. A planet's gravitational pull is determined by the planet's mass. A planet's orbital speed is determined by the the mass of the Sun and the planet's distance from the Sun.
As long as the mass on the end is much greater than the mass of the string it's hanging from, the mass has no effect at all on the speed or the period.
The only way that mass can have an effect on distance is if you're paying a taxi driver with mass.
An object's speed is (distance it travels) divided by (time to cover the distance). The object's mass doesn't matter at all.
The mass of the Sun and the distance between the planet and Sun. As the Sun's mass is (more or less) constant, all we need to know is the distance. Technically this is called the "semi major axis" of the elliptical orbit. (If you wanted to be really, really accurate the mass of the planet does have a very very small effect.)
depends on mass and if you include the air. same mass and not including the air they both weigh the same, air just expands the balloon and lowers the effect of gravity.
The car's mass should have no effect on that speed.
I cannot say about "lenght", but distance is a measure of length so length affects distance. Speed is the rate of change of distance (over time) so length affects speed. Mass does not significantly affect speed or distance but, because they are affected by acceleration and acceleration is affected by mass (for a given force), then mass affects them. Also, mass affects space time and the presence or absence of mass changes the lines along which distances are measured and so distances and speed are affected.
Mass has no effect on torque. Torque is the product of distance (from the axis), force, and an angular function. Mass can, however, make the turbine more stable - it will take longer to react to variations in wind. More mass will increase the MOMENT OF INERTIA (rotational inertia).
