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.
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.

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.

If Earth's axis were not tilted, could any area have both a hot summer and a cold winter?
Answer: What if though the Earth was not tilted? In this case the plane of the Earth's poles would always be perpendicular to the sun. The sun would always be just on the horizon 24 hours a day on every day at the poles. ... It would still be warm at the equator and cold at the poles.
Explanation: Hopefully this Helped
If the earth axis was not tilted the sun would only shine in one place. (the middle) Leaving the rest of the world dark and cold. And no with out the tilt seasons would simply disappear. With out the tilt we would surely be frozen or just really hot.
Hope this helped!!!

What does latitude have to do with the prevailing westerlies?
Answer:
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
Explanation:
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.
Answer:
the westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
Explanation:
I know how the voltage increasing/not enough/stays the same and how long the battery lasts with series and parallel connections. But can someone explain the path electrons goes when you serie/parallel connect the batteries. I understand it with lamps but not batteries. Try to explain it as simple as possible because I'm a bit too young for this but I'm curious
Answer:
It comes out the positive side of the battery and goes in to the negative side of the battery
Explanation:
There are already electrons in wires in a circuit before you add the battery. By adding the battery, you're giving the electrons the energy it needs to move along the circuit.
In a series circuit, the circuit is one continuous loop so there is only one path for the electrons to go - out of the positive side of the battery and around the circuit then goes back into the negative side of the battery.
However, with a parallel circuit, there are two or more ways the electrons can go so they take the path of least resistance. The electrons still go out the positive side of a battery but along the circuit, the electrons will go through the path of least resistance ( I tend to think of it like a net with holes in it - the lower the resistance the bigger the holes for the electrons to go through so more can fit in a set amount of time ) but the electrons still go out of the positive side and in through the negative

Describe tectonic plates and explain how they “float” on the Earth’s surface (what do they float on and what causes their movement). (site 1)
Answer:
There is constant heat and radiation given off from the center of the Earth. That energy is what constantly heats the rocks and melts them. The tectonic plates are floating on top of the molten rock and moving around the planet.
Explanation:
The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
All the following are tiny particles that are parts of atoms EXCEPT:
A: Neutrons
B: Protons
C: Electrons
D: Molecules
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
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.
