Answer:
chemical change through chemical process .
physical change means change in dimension.
A chemical change involves a change in the substance's composition, creating new substances with different properties, typically through reactions such as rusting or combustion. In contrast, a physical change alters a substance's form without affecting its composition, as in melting or condensation processes. The processes can also be classified as exothermic (releasing heat) or endothermic (absorbing heat).
The difference between a chemical change and a physical change pertains to the composition of the substance in question. A chemical change always results in the production of a new substance with different properties from the original matter. For example, the formation of rust from iron, or the combustion process in burning, are chemical changes. These result in the creation of substances distinct from the original matter.
On the other hand, physical changes do not affect the composition of the substance, but alter its state or form, such as the melting of ice into water or the condensation of steam into liquid water. These changes, while observable, do not produce new substances, hence maintaining the original properties of the matter.
Physical and chemical changes can also be differentiated based on whether they release or absorb heat, with exothermic processes releasing heat and endothermic processes absorbing heat. For example, the burning of a fuel is an exothermic process, while the operation of a cold pack is an endothermic process.

Answer: The diameter of the circular path is 2.96m
Explanation: centripetal acceleration = tangential speed^2 / radius of the circular path.
Centripetal acceleration = 2.7m/s^2
Tangential speed = 2.0m/s
Radius = 2.0^2 / 2.7 = 4/2.7
= 1.48m
Diameter = radius*2
= 1.48*2 = 2.96m.
