A hot air balloon descended 99.6 meters in 12 seconds what was the balloons average rate of descent in meters per second?

"Rate of descent" is a speed; so the idea is to divide the distance by the time.

Is incline the antonym of descent?
Ascent is an antonym of descent.
Who is ones lineal ascendant?
One's lineal ascendant is an ancestor in the direct line of descent, such as a parent, grandparent, great-grandparent, and so on. They are the individuals from whom a person is descended through a lineage of parent-child relationships.
What is natural descent and legal descent?
Natural descent is basically another term for generations (as in a family-line). Legal descent is a term that deals with inheritance rules that were established to describe what happens if someone passes away and leaves no legal will.
What is the definition of the word matrillineal?
tracing descent through the mother.
What happens when a lineage splits into two or more lines of descent.?
speciation
Hot air balloons have a gas heater attached to them the pilot can turn the heater on the balloon and the balloon will go high why?
Hot air balloons have a gas heater that is generally powered by propane. When the pilot turns the heater on, the balloon will fly high due to the hydrocarbon chamber that allows the pilot control of ascent and descent of the hot air balloon.
How does a balloon pilot control BOTH acsent and descent of a balloon?
A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
Why air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
What does the principle of common descent imply about humans?
Apes and humans descended from the same common ancestor.
Why do hot air balloons have sandbags?
A hot air balloon needs to be slightly negatively bouyant. If a particular design can lift 1000lbs, an ideal flight weight might be 900 lbs so that, in the event of a burner failure, the balloon will slowly descend. If the payload for a given flight is only 600lbs (fuel, pilot, passengers) then 300 lbs of ballast (sandbags) will be needed to keep the bouyancy in the correct range. ------------------------------------------------------------------------------------------------ Sandbags or other ballast is used mostly for helium balloons, not hot air balloons. The rate of descent of a hot air balloon is controlled by the time the burners are burning. If it is going down too fast, you burn longer. You may have two burners but if you lose one, the other one can keep the balloon aloft. they are always much larger than needed. The design weight is based upon the volume of the balloon and a particular temperture of the air in the balloon which must be below the melting point of the fabric. Typically you don't need ballast to adjust payload in a hot air balloon. IN a helium balloon, the only way you can go back up after starting a descent (by dumping helium) is the drop some weight. So ballast would be helpful with helium balloons.

Principle that states that living species are descended from ancient ones' descent with?
Modification:p hope this helped
How does a hot air balloon return to Earth's surface?
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
What is the principle that states that all species have descended from a common ancestor?
yes, theses ancestors are called common decent
