The Correct choice is ~
MoleculesThe other three (Neutrons, Protons, and Electrons) are subatomic particles found inside an atom, where as the Molecules are substances that have atoms as it's constituent particles.
The requried, molecules are not tiny particles. Option D is the right choice.
What is an atom?An atom is the smallest unit of matter that retains the properties of an element. Atoms are composed of three types of subatomic particles: protons, neutrons, and electrons.
Here,
Molecules are not tiny particles that are parts of atoms. Rather, they are formed when two or more atoms combine chemically.
Neutrons, protons, and electrons, on the other hand, are the three types of particles that make up atoms. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus. These subatomic particles are responsible for the properties and behavior of atoms and the elements they form.
Thus, the requried, molecules are not tiny particles. Option D is the right choice.

There are many uses for permanent magnets and temporary magnets like an electromagnet. Electric appliances with electric motors use magnets to turn electricity into motion. Other examples include electric toothbrushes, fans, lawnmowers, and anything else containing a motor.
Magnets are used to hold doors closed, such as in refrigerators, kitchen cabinets and others. Magnets are also used to read and write data on a computer's hard drive or on old-fashioned cassette tapes. There are more magnets in headphones and stereo speakers which help to turn stored music back into the sounds you can hear.
In summary, magnetism is another property of some kinds of matter. There are two poles to a magnet, the south pole and the north pole. Like poles repel and unlike poles repel. There are two different kinds of magnets, temporary and permanent. A temporary magnet can be made by using electricity. All magnets contain an invisible electromagnetic field which surrounds the magnet. There are many uses for magnets, from holding doors closed to helping music sound better with the magnets inside of speakers.
Based on the information provided above how would you describe a magnet?
Answer:
A magnet is a piece of metal with a strong attraction to another metal object. The attraction a magnet produces is called a "magnetic field."
This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, and so on. and attracts or repels other magnets.
Most magnets are made of iron, and magnets are used in many common items like cassette tapes, credit cards, toys, and compasses. Magnets are used to make a tight seal on the doors to refrigerators and freezers.

When rain falls to the earth, it just doesn't sit there. Instead, the rain water starts moving. Some of the precipitation seeps into the ground to replenishing groundwater. However, most of it flows downhill as runoff. Runoff is important in filling rivers and lakes, but it also changes the landscape by erosion and can be a powerful mover. Flowing water is a powerful force, capable of moving boulders and carving out canyons. Runoff has an impact on streams and rivers, but it also has an impact on the ocean system. What can you infer about the impact of runoff on Ocean life? Choose ALL that apply.
A) Runoff drops a lot of sediment in the ocean, decreasing salinity.
B) Runoff builds up the coastline, depositing sediment, disrupting habitats of marine wildlife.
Runoff can lead to overgrowth of algae that can cause oxygen deprivation and create a dead zone.
C) Runoff carries pollutants into the ocean, causing illness and death of vulnerable marine populations.
D) Runoff can carry bacteria, viruses, and other pathogens from pet and livestock waste that can harm shellfish and other marine organisms.

Caleb is investigating the effect of friction on the motion of an object. He uses the following supplies for the investigation:
a wooden block
three ramps, each ramp is the same height and length but has a different surface (smooth wood, carpet, rough sandpaper)
a stopwatch
Caleb tests his hypothesis that the smooth wood ramp surface causes less friction than the carpet and that the carpet causes less friction than the rough sandpaper.

Sarah and Charlie both investigated the properties of rocks they found while on a walk. Take a look at the table with their observations. What was the difference between the two sets of observations?
Sarah's Observations Charlie's Observations
The mineral was metallic. The mineral was non-metallic.
The mineral had cleavage. The mineral did not have cleavage.
The mineral was red. The mineral was red.
The mineral had luster. The mineral had luster.
a Sarah observed that the mineral was metallic and red.
b Charlie observed that the mineral was red and had luster.
c Sarah observed the mineral had cleavage and was metallic.
d Charlie observed the mineral was non-metallic and had luster.
Answer:
b
Explanation:
Answer: C. Sarah observed the mineral had cleavage and was metallic.
Explanation: The answer is C because the question is asking about the difference in their observations. Sarah claimed the mineral had cleavage and was metallic, while Charlie said the opposite.

What does latitude have to do with the prevailing westerlies?
Answer:
Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. ... This creates frictional or drag in the motion which ultimately slows the Westerlies down. The strongest westerly winds in the middle latitudes can come in the Roaring Forties which is between 40 and 50 degrees latitude.

Derrick created a table of his observations from one trial of an investigation into whether a charged object will attract or repel an uncharged object.
Which statement best explains an incorrect conclusion you might believe without repeated trials?
Object Trial 1
negatively charged attract
positively charged nothing
A) Negatively charged objects repel uncharged objects.
B) Negatively charged objects are attracted to uncharged objects.
C) Positively charged objects do not attract or repel an uncharged object.
D) Positively and negatively charged objects react differently to uncharged objects.
Positively charged objects do not attract or repel an uncharged object. The correct option is C.
What is electrostatics?Electrostatics is the study of stationary electric charges. Electric charge is the charge associated with matter that causes it to create and experience a magnetic and electric effect.
When a plastic rod is touched with fur or a glass rod is rubbed with silk, pieces of paper are attracted, indicating that both rods are electrically charged.
Two particles with opposite charges repel each other, whereas two particles with opposite charges attract each other (see Coulomb's law). The electric force between two charged particles is substantially stronger than the gravitational force.
Therefore, the positively charged objects do not attract or repel an uncharged object. The correct option is C.

Another method in creating a temporary magnet is by using electricity. This can be done by wrapping an iron nail with a coil of wire. By passing electricity through the coil of wire the iron nail will become a temporary magnet or an electromagnet. The strength of the electromagnet depends on the size of the electric current and the number of times the coil is wrapped around the nail. If the electricity stops flowing through the coil the nail will no longer be magnetic.
Write a one sentence summary of the above paragraph.
One method of creating a magnet is coiling wire around a nail and running electricity through it, to make the magnet stronger coil more wire and increase the Voltage.

how is sunlight related to seasons and the tilt of the earths axsis
Answer:
The seasons are caused by the tilted axis of the Earth. Over the course of the year, various portions of the planet are exposed to the Sun's most direct rays. As a result, as the North Pole tilts toward the Sun, the Northern Hemisphere experiences summer. In addition, when the South Pole tilts toward the Sun, it is winter in the Northern Hemisphere, and vice versa.
