Where is the magnetic field strongest?
A. closest to the wire
B. Farthest from the wire

Answers

Answer 1

Answer:

In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as 1/r1/r where rr is the distance from the wire. This can change a bit depending on the length and shape of the wire. Far enough away, the magnetic field decays as 1/r21/r2 .

Answer 2

Answer:

Closest to the wire

Explanation:

In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as where is the distance from the wire. This can change a bit depending on the length and shape of the wire.

Explanation:

After the first four games of a professional football season, three players scored a total of 80 touchdowns. Duke Johnson scored 14 of the touchdowns. Josh McCown scored 40% of the touchdowns. Andre Roberts scored the remaining touchdowns. How many touchdowns did Andre Roberts score?.

Answers

The number of touchdowns scored by Andre Roberts = 34 touchdowns

Given data :

Total number of touchdowns = 80

Number of players = 3

Determine the number of touchdowns scored by Andre Roberts

Player 1 ( Duke Johnson ) scored = 14

Player 2 ( Josh McCown ) scored = 40% of 80 = 32

∴  number of touchdowns scored by player 3 ( Andre )

  = 80 - ( 14 + 32 )

   = 80 - 46  = 34 touchdowns

Hence we can conclude that the number of touchdowns scored by Andre is 34 .

Explanation:

He atoms are smaller than Ne atoms (4AMU vs 20AMU).  Although the kinetic energy and concentrations are the same (same temperature and each have 0.5 mole  in 10.0L containers), the kinetic energy is a product of mass and velocity.  Since the Ne mass is greater, it will have a lower speed, thus taking longer to bounce out the pinhole.

Answers

Answer:

Thomson  placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery, minus the mass of each particle was much, much smaller than that of any known atom. Thomson repeated his experiments using different metals as electrode materials, and found that the properties of the cathode ray remained constant no matter what cathode material they originated from. From this evidence, Thomson made the following conclusions:

The cathode ray is composed of negatively-charged particles.

The particles must exist as part of the atom, since the mass of each particle is only ~1/2000 the mass of a hydrogen atom.

These subatomic particles can be found within atoms of all elements.

While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.

B. The size of Fnorm is the same as the size of Ffric
C. The size of Ffric is the same as the size of Fapp:
D. The size of F
app is the same as the size of Fgrav

Answers

The statement is true in this situation is C. The size of Ffric is the same as the size of Fapp:

From the diagram, since the body is in equilibrium, the sum of vertical forces equals zero. Also, the sum of horizontal forces equal zero.

So, ∑Fx = 0 and ∑Fy = 0

Since Fapp acts in the negative x - direction and Ffric acts in the positive x - direction,

∑Fx = -Fapp + Ffric = 0

-Fapp + Ffric = 0

Fapp = Ffric

Also, since Fgrav acts in the negative y - direction and Fnorm acts in the positive y - direction,

∑Fy = Fnorm + (-Fgrav) = 0

Fnorm - Fgrav = 0

Fnorm = Fgrav

So, we see that the size of Fapp equals size of Ffric and the size of Fnorm equals the size of Fgrav.

So, the correct option is C

The statement which is true in this situation is C. The size of Ffric is the same as the size of Fapp.

4Fe + 3O2 → 2Fe2O3

Iron (Fe) reacts with oxygen (O2) to form iron oxide. A scientist adds 15.4 grams of Fe to 3.6 grams of O2 to start the reaction. All of the iron and oxygen react to form iron oxide. Explain in detail how you can determine how many grams of iron oxide will be produced.

Use the law of conservation of matter in the explanation.

Answers

Answer:

14.54 g Fe2O3

Explanation:

The first step would be to balance the equation but since it's already balanced we don't have to worry about that.

Through the balanced equation, you can find the stoichiometry of the reaction, that is:

4 moles of Fe, react with 3 moles of O2, to produce 2 moles of Fe2O3

Chemistry (accurately stoichiometry) is all about ratios and proportions. The balanced equations gives you the standard ratio by which moles are produced.

So the next step (shown in the paper), is to convert the grams that are giving you in Moles, and you do this by dividing the number of grams given by the molar mass of the substance. The molar mass is the number of grams by which you can find exactly 6.022x10²³ molecules (one mole) of one specific substance.

15.4 g of Fe= 0.28 mol Fe

3.6 g of O2= 0.11 mol O2

Now that you have the quantity of moles, what you need to do is to look for the limitant reactant.

In a balanced equation, the number of moles in the reactants are the rules and they're gonna react completely with each other. If you want x quatity of reactants to react completely, then you will have to respect the proportion to the ratio given in the balanced equation.

But you will rarely follow the proportion so there will usually be a reactant that's gonna be limiting the reaction and one that is in excess. And how do you find this? Well, the easiest way to do it is:

Dividing the number of moles obtained by x element the coefficients of that element in the balanced equation. The one that has the smallest ratio, is the limitant reactants.

Since the limitant reactant is gonna be limiting the reaction, all the stoichiometric procedures should be calculated through it, and in this case, the limitant reactant is O2.

But then how to establish the stoichiometric rule to find the number of Iron oxide (III) that's being produced?

Look back to the stoichiometry of the reaction:

To produce 2 moles of Fe2O3, you need 3 moles of O2.

But you have 0.11 mol O2.

Then establish a factor of conversion (shown in the picture)

The result is 0.07 mol of Fe2O3, but you need the answer in grams so you find the molar mass of Fe2O3 and then multiply it by the number of moles (0.07)

The answer is 14.54 g of Fe2O3

In one to two sentences, describe an experiment that would show that intramolecular forces (attractions between atoms within molecules) are stronger than intermolecular forces (attractions between molecules).

Answers

Answer:

If the molecules have similar molar masses and similar types of intermolecular forces, look for the one that is the most polar or that has the most electronegative atoms or the most hydrogen bonding groups. That one will have the strongest IMF's overall.

Explanation:

An experiment that would show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

Intramolecular forces are the forces of attraction that hold atoms together within a molecule. Intramolecular forces require a high amount of energy to splits atoms or molecules in a chemical bonding.

Intermolecular forces are weaker forces of attraction that occur between molecules. They require lesser energy to splits molecules compared to intramolecular forces.

An experiment that show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

In the process, the energy required to change the state from ice to steam water is more than intermolecular forces.

Thus, we can conclude that this experiment shows that the intramolecular forces are stronger than the intermolecular forces.

The etymology of the prefix cat- means the way down: so think of the sun setting down and losing light. Cat = losing electrons (Such as in a CAThode ray).

The etymology of the prefix -an means upwards. So think of the sun rising up and becoming brighter. An = gaining electrons and becoming overall more negative as electrons are negatively charged.
