I would say dust and plastics for SP/2 because if you actually try to light them up they won catch on fire
By velocity function, the total distance is 8m.
We need to know about velocity to solve this problem. The velocity can be determined as
dV = dX / dT
dX = dV . dT
X = ∫dV . dT
where dV is velocity, dX is distance, dT is the time.
From the question above, we know that:
V(t) = sin(t) m/s
xo = 8 m
to = 0 s
t = 2π s
By substituting the parameters, we can determine the distance
X = ∫dV . dT
Integrate from t = 0 to 2π
X = ∫sin(t) . dT
X = [-cos(t)] + xo
the value of [-cos(t)] + xo from t = 0 to 2π is
X = [-cos(2π) - (-cos(0))] + 8
X = (-1 + 1) + 8
X = 8 m

Answer:
Melting point of a substance is the temperature at which a substance changes from a solid to a liquid. A change of state like melting is a physical change because it doesn’t alter the identity of the substance. In other words, melting point is a physical property because you can determine an object’s melting point without changing the substance. For example, when a substance like ice melts into water, the identity of the substance doesn’t change; the substance is water before and after the physical change. On the other hand, flammability is a chemical property because burning an object is a combustion reaction that leads to the creation of new substances. When you burn a piece of wood, it reacts with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.

There are a lot of examples to choose from.
