Wave A has a long fetch. Wave B has a short fetch. Which of the following statements is true? Wave A is more powerful than Waveb. Wave B is more powerful than Wave
a. Both waves are equally powerful.
Answers
Answer
Correct answer is
wave A is more powerful than wave B
Explanation
Fetch of a wave is the length of water over which a wind blow. It is clear that the wave which has longer fetch will have higher energy level. And higher energy level wave will be more powerful that wave which has short fetch. hence wave A which has longer fetch than wave B will be more powerful that wave B.
Longer Fetch tend to create a higher energy level, which make the wave with longer fetch is stronger than the one with shorter fetch

Explanation:
Nicolaus Copernicus gave the heliocentric theory that sun is at the center if the solar system and all the planets and the moons revolved wound it. according to him, the planets revolved around the sun in circular paths.
But Kepler suggested a different shape of the orbit. According to the laws o planetary motion given by Kepler, the planets revolve around the sun in an elliptical orbit. The sun is at one of its focus.

Explanation:
Energy released in this process is given by
here we have
since here mass of two electrons converted into energy so we have
so here energy released is the energy of rest mass energy due to two charges i.e. electrons and positrons
The minimum total energy released when an electron and its antiparticle (positron) annihilate each other is 1.64 x 10⁻¹³ J.
What is the minimum total energy released?
The minimum total energy released when an electron and its antiparticle (positron) annihilate each other is calculated as follows;
E = Δmc²
where;
- m is the mass of the two electrons
- c is speed of light
E = (2 x 9.11 x 10⁻³¹) x (3 x 10⁸)²
E = 1.64 x 10⁻¹³ J

atoms or molecules
Explanation
A pure gas such as argon or neon is made up of individual atoms. Other compound gasses such as oxygen or carbon dioxide are made up of elements.
Protons, neutrons and electrons are parts of an atom. They are not actually particles but charges.
The answer to the question is atoms or molecules.
