What happens when a wire passes through a magnetic field?
Answer:
If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving).
Explanation:
Answer:
When a conductor moves through a magnetic field, there will be a generated motional emf. This is one example of Faraday's Law and it arises from the magnetic force. The voltage generated in a length of wire, presuming that the entire length moves through a uniform field, is given below.

How do Earth’s plates able to move?
Answer:
Plates at our planet's surface move because of the intense heat in the Earth's core
Explanation:
Hopefully this helps, I believe in you! ^^
Answer/Explanation:
movement can be cause by the intense heat in the earth's core, which causes molten rock in the mantle layer to move. it moves in a pattern called 'convection cell' which can form when the warm material rises, then cools, and eventually sink down. then the process repeats (cooled, warms up and rises.. etc..)

What is the empirical formula for a compound that is comprised of 54.0% sodium, 8.50% boron, and 37.5% oxygen by mass?
A) Na2B2O3.
B) Na3BO3.
C) Na3B2O2.
D) Na4BO4.
Answer:
B) Na3BO3.
Explanation:
Hello!
In this case, since percent compositions are used to identify the empirical formula of an unknown compound, we can assume we have 54.0 g of sodium, 8.50 g of boron and 37.5 g of oxygen, and we compute the moles of each one:
[tex]n_{Na}=54.0g*\frac{1mol}{23g} =2.35mol\\\\n_B=8.50g*\frac{1mol}{11g}=0.773mol\\\\n_O=37.5g*\frac{1mol}{16g}=2.34mol[/tex]
Now, we divide by the moles of boron as those are the fewest:
[tex]Na:\frac{2.35}{0.773}=3\\\\B:\frac{0.773}{0.773}=1\\\\O=\frac{2.34}{0.773}=3[/tex]
Thus, the empirical formula is B) Na3BO3.
Best regards!

Explanation:
The element Indium with atomic number 49 will have 49 protons and 49 electrons in it.
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies and the nearest noble gas is Krypton with 36 electrons.
The electronic configuration in terms of noble gas configuration is:
[tex]In:49:[Kr]4d^{10}5s^25p^1[/tex]
The noble-gas notation for the element indium is [Kr} 4d¹⁰5s²5p¹. The correct option is B. [Kr] 5s2 4d10 5p1
From the question,
We are to write the electron configuration of the element Indium, using the appropriate noble gas notation.
The noble gas that comes before Indium (In) is Krypton (Kr). Therefore, the noble gas that will be used in the notation is Krypton.
Indium has an atomic number of 49 while Krypton has an atomic number of 36. This means we will fill in 13 more electrons.
The electron configuration for the element indium using the noble-gas notation is
[Kr} 4d¹⁰5s²5p¹
Hence, the noble-gas notation for the element indium is [Kr} 4d¹⁰5s²5p¹. The correct option is B. [Kr] 5s2 4d10 5p1

How is an athlete's body different from a healthy body? Discuss what you learned in class today.
Answer:
Lower Heart Rate
Athletes' heart rates tend to be lower than heart rates of non-athletes. A low resting heart rate is generally a sign of good cardiovascular fitness and efficiency. A well-trained athlete may have a normal resting heart rate of only 40 beats per minute, compared with the average heart rate that ranges from 60 to 100 beats a minute.
Lower Disease Risk
Athletic types may have better overall health and be less apt to develop certain diseases. Regular exercise boosts your immune system and lowers the risk of serious health conditions such as cancer and heart disease. Physical activity can also reduce the risk of type 2 diabetes and osteoporosis while helping to manage cholesterol levels and blood pressure. You gain about two hours of additional life expectancy for each hour of regular exercise, according to the American Heart Association.
Psychological Effects
Athletes may have better mental clarity and focus than non-athletes. Exercise increases the flow of oxygen, which has a direct impact on brain function, explains the American Heart Association. Exercise can help improve your memory and reduce negative feelings, such as anger, tension, anxiety and depression.
A comprehensive study of the academic performance of North Carolina high school student-athletes in North Carolina over a three-year period attests to the positive psychological effects of athletic capabilities. Researchers discovered obvious differences between athletes and non-athletes. The study of nearly 127,000 high school students found dropout rates were lower and grade point averages were higher in students who participated in sports. The study was led by Dr. Roger Whitley in collaboration with the North Carolina High School Athletic Association.
Motivated by Excellence
Athletes, especially competitive athletes, have high ambitions. It's a trait that allows them to persevere through setbacks and failures and to come out the other side stronger. Athletes are highly motivated individuals who set their sights on a prize and are single-minded in their pursuit of excellence. They are propelled by passion to become the best they can be and the benefits of that inner drive are a higher level of self-esteem and confidence.

What is the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate
into 355 mL of water?
Answer: 40 + 2x14 + 6x16 = 164g/mole
54.3g x [1mole / 164g] = 0.331moles
355mL x 1L / 1000mL = 0.355L
molarity = 0.331moles / 0.355L =
00
Explanation:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
[tex]Molarity=\frac{n}{V}[/tex]
n is the number of moles of the compound[tex]n=\frac{mass}{molar \ mass}[/tex]Mass of calcium nitrate = 54.3gMolar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol[tex]n=\frac{54.3}{164.088 } \\n=0.331 moles[/tex]
Get the required molarity;
[tex]Molarity=\frac{0.331}{0.335}\\Molarity= 0.9881 M[/tex]
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

Would you expect salts like NaCl, which have singly-charged ions, to have larger or smaller lattice energies compared to salts like CaO which are composed of doubly-charged ions?
Answer:
NaCl has a smaller lattice energy compared to CaO
Explanation:
We have remember that lattice energy increases as the size of the ions in the ionic solid decreases. According to Oxford dictionary; lattice energy is "a measure of the energy contained in the crystal lattice of a compound, equal to the energy that would be released if the component ions were brought together from infinity."
We know that the larger the magnitude of charge on a cation the smaller in size the cation is and the size of anions increase from left to right in the periodic table. Hence Ca^2+<Na^+ and O^2- < Cl^-. Therefore the lattice energy of CaO is greater than that of NaCl.
Which electron configuration shows an atom with 6 valence electrons?
Answer:
Valence electrons are the electrons in the outermost shell, or energy level, of an atom.example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.
A current of 5.29 A is passed through a Sn(NO3)2 solution for 1.30 h . How much tin is plated out of the solution?
Answer:
15.26 g of tin
Explanation:
Given that the equation of the process is;
Sn^2+(aq) + 2e ------> Sn(s)
Since 1e = 1F= 96500 C
but q =It
t is in hours so it must be converted to seconds, the SI unit of time
Hence;
119g of tin is deposited by 2 * 96500 C
xg of tin is deposited by 5.29 * 1.30 * 60 * 60
x = 119 * 5.29 * 1.30 * 60 * 60/ 2 * 96500
x = 2946106.8/193000
x= 15.26 g of tin
A current of 5.29 A is passed through a Sn(NO₃)₂ solution for 1.30 hour, the amount of tin plated is 15.26 grams.
How do we calculate mass?Mass of any deposited susbatnce that is obtained by the passing of current will be calculated by using the Faraday's Law as:
W = ECT/F, where
W = required mass of deposited tin
C = current = 5.29 A
T = time period = 1.30hr = 4,680sec
F = faradays constant = 96500C
E = equivalent mass
Equivalent mass will be calculated as:
E = molar mass/charge on atom = 119/2 = 59.5 g/equ
On putting all these values in the above equation, we get
W = (59.5)(5.29)(4680) / 96500
W = 15.26 g
Hence mass of tin is 15.26 g.
