Answer:
Fusion
Explanation:
A chemical reaction can be defined as a reaction in which two or more atoms of a chemical element react to form a chemical compound.
On the other hand, a nuclear reaction can be defined as a reaction in which the nucleus of an atom is transformed by being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive element.
This ultimately implies that, during fusion, two smaller atoms fuse to form a larger atom. Thus, fusion involves the joining of two smaller nuclei of atoms to form a single massive or heavier nucleus with the release of energy.
Additionally, the energy that holds the neutrons and protons found in the nucleus of an atom together is known as Nuclear energy.
Answer:
D) The given reaction is Exothermic, because energy is released
Explanation:
Here, given that Zinc is added to a beaker containing hydrochloric acid.
Also, the beaker gets warm.
⇒The energy is released in the form of heat.
EXOTHERMIC reactions are those type of reactions in which energy is released in the form of heat.
When the beaker gets warm, the reaction is exothermic in nature.
Hence, the given reaction is Exothermic, because energy is released

Espero esto te ayude!
Answer:
r = √ x² + y² and θ = tan⁻¹ y / x
Explanation:
The polar coordinates are obtained by transforming the Cartesian coordinates (x y) into others (r tés), for this we use to find r the Pythagorean theorem
r = √ x² + y²
To find teas we use trigonometries
tan θ = y / x
θ = tan⁻¹ y / x
In general the angle can be given in any unit, but the most used in physics is in radians
