Answer: The density and the temperature
Explanation:
Sound needs a medium to travel. The medium particles vibrate and transfer energy. Sound travels by compression and rarefaction of the medium particles. Thus, the speed of the sound varies with the density of the medium. If the medium is denser, the particles would be closer and energy would transmitted faster because there would be more rapid collisions which means that speed of the sound will be greater in a denser medium.Thus, speed of sound is fastest in solids than in liquids and is least in gases.
Speed of sound also depends on temperature. Greater the temperature, the particles would vibrate faster which would lead to again more inter particle collisions. Thus, the speed of sound would increase with increase in temperature.

Explanation:
Consider a mass of 10 kg, so m = 10
Let's say we apply a net force of 20 newtons, so F = 20
The acceleration 'a' is...
F = ma
20 = 10a
20/10 = a
2 = a
a = 2
The acceleration is 2 m/s^2. Every second, the velocity increases by 10 m/s.
---------------
Now let's double the net force on the object
F = 20 goes to F = 40
m = 10 stays the same
F = ma
40 = 10a
10a = 40
a = 40/10
a = 4
The acceleration has also doubled since earlier it was a = 2, but now it's a = 4.
---------------
In summary, if you double the net force applied to the object, then the acceleration doubles as well.
Acceleration is directly proportional to the net force on an object, and inversely proportional to its mass.
So if an object's mass stays the same while the net force on it doubles, then its acceleration will also double.
We don't know anything about the "trials". This sounds like it might be a follow-up to a lab experiment that was performed when we weren't there.
We also don't know anything about "question 1".
