Describe how magnetic forces and electric forces are similar and different from each other

Chemistry
1 answer:
PtichkaEL [24]3 years ago
4 0

<em>ANSWER:</em>

Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other. ... Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.

According the inverse square law, doubling the distance from the source of the sound, a speaker, for example, will drop the soun
Shtirlitz [24]

Answer:

Yes, I would be able to hear the speaker clearly because the supposedly dropping off of sound as the distance gets farther is counteracted by "reverberations" inside the auditorium.

Explanation:

According to the "Inverse Square Law," if the distance from the sound source is doubled, the intensity of the sound will diminish by 6 decibels. This is true if the situation is in a <em>"free field,"</em> which means the sound has no reflection.

However, this is not the case in an "auditorium." An auditorium causes the <u>"reverberation" of sound. </u>This prolongs the resonance of the sound.  So, this means that even if the sound drops off by a factor of 100 (20 decibels), due to reverberations, the height of the ceiling, the kind of wall and materials used in making the seats also affect the intensity of the sound waves. This is the reason why auditoriums are used as venues for <em>concerts, presentations and the like</em> where a <u>large group of people serve as the audienc</u>e.

In a certain acidic solution at 25 ∘c, [h+] is 100 times greater than [oh −]. what is the value for [oh −] for the solution? in
marishachu [46]

Answer:

1.0 x 10⁻⁸ M.

Explanation:

<em>∵ [H⁺][OH⁻] = 10⁻¹⁴. </em>

∵ [H⁺] = 100 [OH⁻].

∴ 100 [OH⁻][OH⁻] = 10⁻¹⁴.

∴ 100 [OH⁻]² = 10⁻¹⁴.

[OH⁻]² = 10⁻¹⁴/ 100 = 1.0 x 10⁻¹⁶.

<em>∴ [OH⁻] = √(1.0 x 10⁻¹⁶) = 1.0 x 10⁻⁸ M. </em>
