When building electric circuits,_______ flow along the path ( wires, energy source, and resistor(s)).
-neutrons
-matter
-electrons
-protons
Answers
Electron is negatively charged particle. When building electric circuits electron flow along the path. so, option C is correct.
What is Electron ?Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.
The outer shells of atoms in the common items you encounter are made up of matter particles called electrons.
A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of particles within an atom is an electron that is bonded to it.
The other two are protons and neutrons. The nucleus of an atom is made up of electrons, protons, and neutrons together.
Thus, Option C is correct.

Answers
Answer:
I would think B, an estuary. But I'm not sure.
Explanation:
The area where the plants should be find in which the water should be tolerated should be estuary.
What is an estuary?An estuary refer to the enclosed body with respect to the brackish water that have one or more rivers or streams that should be flow into it. Also, there should be free connection to the open sea. It should be considered as the transition zone that lies between the river environment and maritime environment

A coffee cup calorimeter contains 153.21 g of water at 22.50 °C. A 65.454 g piece of iron is heated to 101.62 °C. The piece of iron is added to the coffee cup caloriemter and the contents reach thermal equilibrium at 25.68 °C. The specific heat capacity of iron is 0.449 Jg·K and the specific heat capacity of water is 4.184 Jg·K. How much heat, , is lost by the piece of iron?
Answers
Answer:
Q = 2232J
Explanation:
In the system, the energy that is lost by the iron is:
Q = S*ΔT*m
Where Q is heat, S is specific heat of iron ΔT is change in temperature and m is mass of the piece of iron.
S = 0.449J/gK
ΔT = 101.62°C - 25.68°C = 75.94°C
m = 65.454g
Q = 0.449J/gK*75.94°C*65.454g
Q = 2232J

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)
Answers
Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.
Answer:
A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

PLEASE HELP ASAP
Thank you!!
Answers
Answer:
Yes. The two elements can combine to form different compounds.
Explanation:
Two elements can combine at different ratios.
Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.
There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.
The size of an atom would be described in _______.
Answers
Answer:
atomic radius
Explanation:
so radius
Answer:
Explanation:
The average size of an atom is about 100 picometers or one ten-billionth of a meter. Almost all of the mass of an atom is in its nucleus; almost all of the volume of an atom is occupied by electrons. The number of protons (also known as its atomic number) determines the element. Varying the number of neutrons results in isotopes.
what volume of water has a mass of 1 kg
Answers
Answer:
[tex]V=0.001\ m^3[/tex]
Explanation:
Mass, m = 1 kg
The density of water, d = 1000 kg/m³
We need to find the volume of water. The formula for the density of an object is equal to mass divided by volume. Its formula is :
d = m/V
V is the volume of water
[tex]V=\dfrac{m}{d}\\\\V=\dfrac{1\ kg}{1000\ kg/m^3}\\\\=0.001\ m^3[/tex]
So, the volume of water is [tex]0.001\ m^3[/tex].
Answer:
Volume of water has a mass of 1 kg is explained below in details.
Explanation:
One liter of h2O has a volume of approximately specifically one kilogram when estimated at its maximum frequency, which happens at about 4 °C. It observes, therefore, that thousand of a liter, recognized as one milliliter (1 mL), of h2O has a volume of about 1 g; 1000 liters of h2O has a volume of about 1000 kg (1 tonne).

Substance 2 has a stronger molecular attraction.
What are solids?Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.
Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.
Hence, Substance 2 has a stronger molecular attraction.

An atom has an atomic number of 15 and a mass number of 31. How many protons are there in the atom?
Answers
Answer:
No of protons = 15
Explanation:
Given that,
Atomic number = 15
Mass number = 31
We need to find the no of protons in the atom.
We know that,
No of protons = Atomic no of the atom
No of protons = 15
Hence, there are 15 protons in the atoms.

The answer is B
HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent bond is weaker than ionic bond.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.

Answer:
Yes
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
