Let's start by using the definition of acceleration. Acceleration is defined as the change in velocity over the change in time. In equation, that would be Δvelocity/Δtime. Based on the axes of the given graph, it shows the trend of position over time. So, the slope of the line and the curve shows the change of position over change of time, Δdistance/Δtime. In physics, this is the definition of speed or velocity. So, Maia is incorrect. Both curves show the speed or velocity of the object, and not acceleration. If the graph used a y-axis of velocity instead of position, then only at that instance, would be Maia be correct.
The difference between the two is, the straight line shows constant velocity while the curve line shows changing velocity.
Sound waves travel faster in denser materials and the more dense the material the faster the sound is
Answer:
Tornado
Explanation:
This is because, tornados are heavy constant winds that are blowing around all over causing an unstable atmosphere. Sometimes the weather will change drastically like causing hail, and cold fronts moving in. This is exactly what matches the conditions you show! :)

Answer:
Decomposition reaction.
Explanation:
Decomposition reaction -
It is the type of reaction, where a single entity breaks down into various products under the influence of some external factors , like heat and sunlight , is referred to as a decomposition reaction.
From the question,
The reaction is -
2 HgO → 2 Hg + O₂
Hence ,
A single compound HgO breaks down to two entities , i.e. , Hg and O₂.
The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
