Granite forms when magma cools slowly underground. Granite is an intrusive igneous rock. The answer is letter B. granite is composed mostly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals.
b. False
AND A BRAINIEST!!!
PLEASE I HAVE OTHER HW TO DO:(
Answer:
Explanation:
1. q=mcat
q = (20)(4.184)( 30-20)
q = 836.8
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
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.
(2) electrons and protons
(3) neutrons and protons
(4) neutrons, protons, and electrons
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.

Answer:
water molicules have space between them thus letting the food colour spread without stiring the water.
