Explain why all ores are minerals but all minerals are not ores.

Answers

An ore is a type of rock that contains many minerals. But a mineral is just a part of the ore. So all ores are minerals but all minerals are not ores.

Minerals:Metal bearing substance, found in earth's crust are called minerals
Ore:the Minerals which metals can be obtained on a commercial scale are called Ores
form this definitions we can understand that ores are minerals which is used to obtain metals so, only all ores are minerals but all minerals are not ores.

In your own words, compare and contrast transverse and longitudinal waves. Be sure to include at least one similarity and one difference.

Answers

A transversewave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.

A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling. Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.

Similarities

Both transverse and longitudinal waves carry energy.
Both transverse and longitudinal waves obey the wave equation.
Both transverse and longitudinal waves show behavior such as refraction, reflection, absorption, diffraction, etc.

Differences

The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.

Which subatomic particles are located in the nucleus of an He-4 atom?(1) electrons and neutrons
(2) electrons and protons
(3) neutrons and protons
(4) neutrons, protons, and electrons

Answers

The answer is (3) neutrons and protons. The nucleus of an atom is composed of neutrons and protons. There is only one atom nucleus composed of only protons, Hydrogen. And the electrons are moving in high speed around the nucleus.

The nucleus of an atom contains the majority of its mass and is composed of two types of subatomic particles: protons and neutrons.

1. Protons: Protons are positively charged particles found in the nucleus of an atom. Each proton carries a charge of +1 and has a relatively high mass compared to electrons. The number of protons in an atom's nucleus determines its atomic number, which in turn defines the element. In the case of helium-4 (He-4), it has an atomic number of 2, indicating that there are two protons in its nucleus.

2. Neutrons: Neutrons are electrically neutral particles, meaning they have no net charge. They are also located in the nucleus of an atom. Neutrons contribute to the mass of the nucleus and help stabilize it by balancing the electrostatic repulsion between positively charged protons. Helium-4, being a stable isotope of helium, has two neutrons in its nucleus, along with the two protons.

Electrons, on the other hand, are found in electron shells or orbitals outside the nucleus, not within it. Their role is to move around the nucleus and create the electron cloud or electron configuration, which determines an atom's chemical properties.

In summary, the nucleus of a helium-4 atom consists of neutrons and protons, making option (3) "neutrons and protons" the correct choice. Electrons, which are negatively charged, are located outside the nucleus and are involved in chemical interactions and bonding.
