When fireworks go off, they produce smoke, which is evidence of a new substance being created.
Answer:
340 N
Explanation:
<u>Force formula</u>
The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
<u>Equilibrium</u>
It is a state of rest or balance due to the equal action of opposing forces. equal balance between any powers, influences, etc.; equality of effect. mental or emotional balance; equanimity: The pressures of the situation caused her to lose her equilibrium.<u>

A single-displacement reaction, also known as asingle-replacement reaction, is a type of chemicalreaction<span> where an element reacts with a compound and takes the place of another element in that compound. This type of </span>reaction<span> is typically pictured like this: Here, A replaces B in the compound BC.</span>
Answer:
Heat, in the form of thermal energy, naturally moves from warmer substances to colder ones. When the ocean is warmer than the atmosphere, it transfers heat — through conduction and radiation — to make the air warmer. ... This redistributes thermal energy and causes changes in the weather.
Answer:
The correct option is;
c. Sound wave
Explanation:
The given options effect on mutation are given as follows;
a. Radiation
Radiation such as ultraviolet light and gamma radiation, which are electromagnetic waves, cause mutations by causing the formation of free radicals within an organism's cell resulting in the mutation characteristic effects
b. Smoking of tobacco has mutagenic effects due to the presence of several carcinogenic compounds in cigarettes
c. Sound wave is a form of mechanical wave and has no chemical effects on the chemistry of an organism and therefore does not cause mutation in cells
d. Chemical pollution can contain carcinogenic compounds that can cause mutations in the cells of organisms.
