Answer: It's frequency also increases.
Explanation:
The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. ... The amplitude of a wave is related to the amount of energy it carries. A high amplitude wave carries a large amount of energy; a low amplitude wave carries a small amount of energy.

Kepler did not study the speed of the planets, rather, he studied how the planets move in the solar system. He proposed three laws. As a summary, he described that the planets move around the sun in the shape of an ellipse (orbit), and the Sun being one of the foci. Then, he proposed the period for the planet to complete one revolution around the Sun.
On the other hand, Newton studied the forces acting on the planet (or any object in space) that explain how the planets move around the solar system as described by Kepler. Also, Kepler's observations only apply to planets and not the moons or satellites. Thus, Kepler only made laws from observations, while Newton based it from underlying principles that led him to mathematical equations such as the law of universal gravitation.
Answer:
In asexual reproduction, a single parent produces genetically identical offspring. As prokaryotes do not have a nucleus, and have only one circular chromosome, they do not need to reproduce by the same mechanism as eukaryotic cells; mitosis does not exist in prokaryotic cells.
Explanation:
Answer:
1) P₄ + 5O₂ → P₄O₁₀ redox reaction
2) P₄O₁₀ + 6H₂O → 4H₃PO₄ acid-base reaction
3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄ precipitation reaction
Explanation:
The reactions that take place in the <u>electric furnace method</u> are:
1) P₄ + 5O₂ → P₄O₁₀
This is a redox reaction, because the oxidation state of the reactants is changed.
2) P₄O₁₀ + 6H₂O → 4H₃PO₄
This is an acid-base reaction, because there's an exchange of H⁺ species.
The reaction that takes place in the <u>wet process</u> is:
3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄
This is an precipitation reaction, because a precipitate (a solid phase in a liquid phase) is formed.
