Newton's first law of motion is sometimes called the law of inertia. When the forces acting on an object are balanced, the object is either at rest or moving with a constant velocity. Unbalanced forces can cause an object to accelerate or decelerate. Unbalanced forces can also cause an object to change direction.
Radioactive decay is the loss of energy by unstable atomic nuclei. The reaction shows alpha decay. Thus, option d is correct.
<h3>What is alpha decay?</h3>
Alpha decay is a type of radioactive decay in which an alpha particle or the helium ion is released from the parent cell to produce the daughter nucleus.
The alpha decay in the isotope of the uranium to thorium and an alpha particle is shown as:
²³⁵U₉₂ → ²³¹Th₉₀ + ⁴He₂
In beta decay, a negatively charged electron is emitted along with the daughter nucleus and in gamma decay, gamma rays without charge and mass are emitted.
Therefore, the reaction shows option d. alpha decay.

Answer: In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels
Explanation: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In water waves, energy is transferred through the vibration of the water particles.
Answer:
false
Explanation:
It is a physical reaction because it is being heated.
Answer:
The answer is grass
Explanation:
Grass is a plant, meaning it undergoes photosynthesis to receive its energy from the sun.
