Answer:

<em><u>Gravity</u></em> - is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another.

<em><u>Strong Interaction</u></em> - is the mechanism responsible for the strong nuclear force

<em><u>Weak Interaction</u></em> - is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms

<em><u>Electromagnetism</u></em> - is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Hope this helps!

Which feature of a heating curve indicates a change of state?
Andreas93 [3]
A "heating curve" is a graph that shows the temperature of the substance
against the amount of heat you put into it.

For most of the graph, as you'd expect, the temperature goes up as you
add heat, and it goes down as you take heat away.  BUT ... While the
substance is changing state, its temperature doesn't change even though
you're putting heat in or taking heat out.

So that part of the graph is a horizontal line.

Heptane is always composed of 84.0% carbon and 16.0% hydrogen. This illustrates the law of multiple proportions. conservation of
BigorU [14]

Heptane is always composed of 84.0% carbon and 16.0% hydrogen. This illustrates the "law of definite proportions".

Answer: Option C

<u>Explanation:</u>

Proust's law states that every chemical compound used to made up of element constituents with constant proportions in terms of its mass and also independent from its sources and synthesis method. In 1779, Joseph Proust gave other names to the Proust's law as, the law of composition or definite proportions or constant compositions.

This can understood from given example like: Oxygen is composed of 8/9 of the mass of any sample of pure water while the hydrogen fills up the remaining 1/9 of the mass. The basis of stoichiometry is structured with the law of multiple proportions along the law of definite proportions.

A constant tone is being applied to a speaker. The voltage across the speaker is 5 volts. The voltage across the speaker is incr
lubasha [3.4K]

Answer:

decibel gain is 10 db

Explanation:

given data

voltage v1 =  5 volts

voltage v2 = 15 volts

to find out

decibel gain

solution

we have given that 5 volt voltage that is increase to 15 volts

so

we know here decibel gain formula that is

decibel gain = 20 log(v2/v1)   ....................1

put here value of v1 and v2  in equation 1

decibel gain = 20 log(15/5)

decibel gain = 20 log3

decibel gain = 20 × 0.4771

decibel gain = 9.54 db = approx 10 db

so decibel gain is 10 db

Which of the following is NOT part of the kinetic theory of gases?
padilas [110]

Answer:

Option a

Explanation:

The three basic and major points of the kinetic theory of gases are listed below:

1. In the collision between the gas molecules, no loss or gain of energy takes place.

2. According to the theory, the gaseous molecules exhibits constant and linear motion.

3. The molecules of the gas occupies very little space as compared to the container. Thus the empty space in a gas is not very little.
