One student did an experiment with two unknown minerals, Mineral 1 and Mineral 2. The hardness scale shown below was used for the experiment.


Mineral Talc Gypsum Calcite Fluorite Apatite Orthoclase
Hardness 1 2 3 4 5 6

Any mineral on the hardness scale would scratch minerals below it on the scale. The student tested Mineral 1 and observed that it could scratch only two other minerals on the hardness scale. It was observed that Mineral 2 could scratch only four other minerals on the hardness scale. Which of these is a correct conclusion the student can make about Mineral 1 and Mineral 2?
A) Mineral 1 can be used to scratch talc and Mineral 2 can be used to scratch orthoclase.
B) Mineral 1 can be used to scratch orthoclase and Mineral 2 can be used to scratch talc.
C) Mineral 1 can be used to scratch calcite and Mineral 2 can be used to scratch gypsum.
D) Mineral 1 can be used to scratch gypsum and Mineral 2 can be used to scratch calcite.

Answers

Answer 1
Scale: (soft 1-->6 hardest)
1=Talc 2=Gypsum 3=Calcite 4=Fluorite 5=Apatite 6=Orthoclase

Mineral #1 can only scratch two other minerals therefore it must have a hardness level of 2+1=3 which is Calcite. (scratches talc, gypsum)

Mineral #2 can scratch four other minerals therefore it must have a hardness level of 4+1=5 which is Apatite. (scratches all but Apatite, Orthoclase)

Looking through the possible conclusions.. It looks like answer is D.


Answer 2
Final answer:

Mineral 1 has a hardness equivalent to calcite, and Mineral 2 has a hardness equivalent to apatite. Therefore, Mineral 1 can scratch calcite and Mineral 2 can scratch gypsum.

Explanation:

The hardness scale in the question list minerals according to their hardness. Mineral 1 could only scratch two other minerals, which means that it should rank third on the scale, since it can only scratch minerals 1 and 2. The hardness of Mineral 1 is, therefore, equivalent to that of calcite. Similarly, Mineral 2 could scratch four other minerals, and thus should rank fifth on the scale, after minerals 1, 2, 3, and 4. This means that the hardness of Mineral 2 is equivalent to that of apatite. Therefore, the correct answer is option C) Mineral 1 can be used to scratch calcite and Mineral 2 can be used to scratch gypsum.

Describe the energy transformations that occur from the time a skydiver jumps out of a plane until landing on the ground.

Answers

I think, the skydiver has maximum potential energy before jumping. However, as the skydiver jumps and decreases in height, he increases the velocity. Thus, as soon as the skydiver has jumped he is experiencing kinetic energy. The velocity of the skydiver increases as he moves down wards due to gravitational acceleration until he attains terminal velocity. 
Sample Response: Before jumping from the plane, the skydiver has potential energy. When the skydiver jumps, the potential energy is transformed into kinetic energy, which increases until the skydiver reaches terminal velocity. Potential energy is then transformed into thermal energy.

Just remember that Isotopes are atoms that have the same number of protons as they do in their neutral state, but have more neutrons. 
Remember this:
Mass number = protons + neutrons
neutrons = mass number - protons
protons = atomic number
electrons = protons

Neutrons and protons are found in the nucleus and the circle around it is an orbit, that is where you put the number of electrons. 

Let's take your first question:
a. Carbon: Atomic number is 6 and the mass number is 12. 

neutrons = 12 -6        (atomic number = protons)
               = 6
So draw 6 neutrons in the nucleus and 6 protons in the middle of the circle. And write 6e electrons outside the circle. 

b. a. Carbon: Atomic number is 6 and the mass number is 13
Here you will see something different:

neutrons = 13 -6        (atomic number = protons)
               = 7 
Notice that the number of neutrons changed. All you do is instead of drawing only 6 neutrons, draw 7 and draw 6 protons. 

The name of the atom is Carbon-13 because the number 13 indicates the mass number.

2. The explanation above will lead to the answers for this question. Let's knock out some of those choices.
Compare the 2 carbon atoms, which changed and what stayed the same. The number of protons stayed the same, and so did the atomic number. What changed was the mass number because the number of neutrons changed so your answer would be the third selection.

3.a. Again, take note of the given:
Chlorine: Atomic number is 17 (that stays constant!) the mass number is 35. Name of the atom is Chlorine-35
Neutrons = 35 - 17      17 is the number of protons which is equal to the 
               = 18               atomic number.
So you will draw 17 protons and 18 protons in the middle of the circle and write 17e outside the circle.

3.b. Name of the atom is Chlorine-37
Chlorine:  Atomic number is 17 (This was given already) and mass number is 37.
REMEMBER atomic number = protons
Neutrons = 37 - 17        
                = 20    

So you will draw 20 neutrons and 17 protons inside the circle and on the line of the circle you will write 17e outside the circle. 

Why is the electrons the same as protons because there is no sign to indicate that the atoms are ions so they are all neutral which means that the number of electrons is equal to number of protons. 

Read the sentence. telescopes or satellites _____ that neither mercury nor venus _____ a moon. which pair of verb forms correctly completes the sentence? proves; has proves; have prove; have prove; has

Answers

I believe it is prove;has

Telescopes or satellites prove that neither Mercury nor Venus has a moon.

When there is or in-between two words, the tense is dependent upon the word that comes after or. In other words, the word that is closest to the verb will decide the form of the verb.

Since satellites is a plural form of a satellite, the verb that follows satellites should also be plural. The plural verb in the given options is prove.

As far as the second blank is concerned, you can see Venus is a proper noun; therefore, the verb that comes after Venus should be a singular verb, which in this case is has.

So the complete sentence would become the following:

Telescopes and satellites prove that neither Mercury nor Venus has a moon.

Correct pair: prove:has

The rope will snap if the tension in it exceeds 55.0 n. what is the maximum value of the force f which can be applied?

Answers

Missing part of the text:
"Two masses, m1 = 2.12 kg and m2 = 9.01 kg are on a horizontal frictionless surface and they are connected together with a rope as shown in the figure."
and missing figure (see attachment)

Solution:
We can write Newton's second law for the whole system m1-m2 and for m2 only (2 equations). Only one force (F) acts on the m1-m2 system, while if we consider m2 only we have two forces acting on it: F and T (tension), in the opposite direction. So, the two equations are
[tex]F=(m_1+m_2)a[/tex]
[tex]m_2 a=F-T[/tex]
where a is the acceleration of the system.

From the first equation we get
[tex]a= \frac{F}{m_1+m_2} [/tex]
and substituting it inside the second equation, we get
[tex] \frac{m_2}{m_1+m_2}F=F-T [/tex]
re-arranging, we get
[tex]F=T( \frac{m_1+m_2}{m_1} )[/tex] 

Using [tex]m_1=2.12 Kg[/tex], [tex]m_2=9.01 Kg[/tex], and using the maximum value of T that is allowed not to break the rope (T=55 N), we can find the maximum allowed value for F:
[tex]F=288.8 N[/tex]

What are two ways you can increase the magnetic field of an electromagnetic?

Answers


1).  Wind more turns of wire in the coil around the core.

2).  Increase the electrical current flowing in the wire.
(You can do that by using a battery or power supply with a little more voltage.)

3).  If the core of the electromagnet is anything else but pure iron,
take it out, throw it away, and replace it with a core of pure iron.
Final answer:

To increase an electromagnet's magnetic field, add more turns to the coil and increase the current flowing through it. Inserting a ferromagnetic core can also enhance magnetic field strength, but limitations exist due to coil resistance and the properties of superconducting materials.

Explanation:

To increase the magnetic field of an electromagnet, you can perform the following modifications:

Increase the number of turns in the coil: Adding more turns to the solenoid will enhance the magnetic field as it is directly proportional to the number of turns in the wire.Increase the current: By increasing the electrical current flowing through the coil, the magnetic field will also increase due to the direct relationship between current and magnetic field strength.

Another method often used to enhance the strength of an electromagnet is by inserting a ferromagnetic material, such as iron, within the coil, which acts as a core to concentrate the magnetic field.

However, it is important to note that there are limits to the strength of the magnetic field that can be created. Exceeding certain thresholds can lead to an overheating problem due to coil resistance, or can destroy the superconducting properties if superconducting materials are used.

D) They are different configurations of nitrogen and they consist of the same number of protons and neutrons but each contains a different number of electrons - 7 and 8 respectively. Eliminate

Answers

Answer: A) They are isotopes of nitrogen and they contain the same number of protons and electrons but each contains a different number of neutrons - 7 and 8 respectively.

Isotopes are atoms of a chemical element whose nucleus has the same atomic number, Z, but different atomic mass, A. The atomic number corresponds to the number of protons in the atom, therefore the isotopes of an element contain the same number of protons and electrons (atoms have to be neutral particles). The difference in atomic masses arises from the difference in the number of neutrons in the atomic nucleus.

The image shows a pendulum that is released from rest at point A. Shari tells her friend that no energy transformation occurs as the pendulum swings between point B and point D.

She could agree with Shari because the pendulum is at the same height and would have the same gravitational potential energy at both positions.

She could agree with Shari because the pendulum has the same amount of mechanical energy throughout its swing.

She could disagree with Shari because the pendulum converts kinetic energy into gravitational potential energy, then back into kinetic energy.

She could disagree with Shari because the pendulum converts gravitational potential energy into kinetic energy, then back into gravitational potential energy.

Answers

is  D    the  right  answer

Answer:

She could disagree with Shari because the pendulum converts gravitational potential energy into kinetic energy, then back into gravitational potential energy.

Explanation:

The energy of the pendulum is constantly converted from gravitational potential to kinetic, and back.

In fact:

- the gravitational potential energy of the pendulum is given by:

[tex]U=mgh[/tex]

where m is the mass of the pendulum, g is the gravitational acceleration, and h is the height of the pendulum above the ground

- The kinetic energy of the pendulum is given by:

[tex]K=\frac{1}{2}mv^2[/tex]

where v is the speed of the pendulum.

Therefore, when it is at a higher position, the pendulum has a greater potential energy, while when it is at a lower position, the pendulum has a greater kinetic energy (because its speed is higher).

In this example:

- when the pendulum swings from B to C, part of its gravitational potential energy is converted into kinetic energy (because the height decreases but the speed increases), and when the pendulum goes from C to D, the kinetic energy is converted back into gravitational potential energy (because the height increases and the speed decreases)

The sun may be the most massive object in the solar system, making up 99.8% of the system's total mass, yet compared to other stars, it is actually rather typical. Of all known stars, roughly half are more massive and half are less massive. R136a1, a star that is more than 300 times as massive as the sun, is the most massive star known to exist in the sky. Yet it's not the only star dwarfing the main star of the Earth.

The Tarantula Nebula contains RMC 136a1, more often known as R136a1, which is located around 163,000 light-years from Earth. The Great Magellanic Cloud, one of the Milky Way's satellite galaxies, contains this huge star, which is located outside of our galaxy.

In 1960, astronomers at the Radcliffe Observatory in South Africa discovered the RMC 136 star cluster. More than 200 incredibly brilliant stars were discovered in the cluster when the Hubble Space Telescope analysed the system; the most massive of these stars was known as RMC 136a1.

Plug in the values in equation(A):

A => WaveLength = [tex] \frac{3 * 10^{8}}{13*10^{3}} [/tex]

Ans: Wavelength = 23.077 kilometers.
-i

Final answer:

The wavelength of a 13.0 kHz VLF radio wave in air is calculated using the formula λ = v / f, with the speed of light as the speed. This yields a wavelength of about 23,077 meters, or 23 kilometers, illustrating the long-distance propagation capabilities of VLF radio waves.

Explanation:

The question pertains to calculating the wavelength of a 13.0 kHz VLF (Very Low Frequency) radio wave in air. The formula that links the wavelength (λ), frequency (f), and speed (v) of a wave is λ = v / f. For electromagnetic waves in air, the speed can be approximated to the speed of light, which is roughly 3×108 meters per second (m/s).

Using this formula:λ = 3×108 m/s / 13,000 Hz = approximately 23,077 meters.

Therefore, the wavelength of a 13.0 kHz VLF radio wave in air is about 23 kilometers. This large wavelength is characteristic of VLF radio waves, allowing them to propagate over long distances and curve around the Earth's surface, making them useful for communication over the horizon without the need for satellite or cable transmission.

A sprinter set a high school record in track and field, running 200.0 m in 20.6 s . what is the average speed of the sprinter in kilometers per hour?

Answers

Answer : The average speed of the sprinter is, 34.95 Km/hr

Solution :

Average velocity : It is defined as the distance traveled by the time taken.

Formula used for average velocity :

[tex]v_{av}=\frac{d}{t}[/tex]

where,

[tex]v_{av}[/tex] = average velocity

d = distance traveled = 200 m

t = time taken = 20.6 s

Now put all the given values in the above formula, we get the average velocity of the sprinter.

[tex]v_{av}=\frac{200m}{20.6s}\times \frac{3600}{1000}=34.95Km/hr[/tex]

conversion :

(1 Km = 1000m)

(1 hr = 3600 s)

Therefore, the average speed of the sprinter is, 34.95 Km/hr

The average speed of the sprinter in kilometers per hour is about 35.0 km/h

Further explanation

Acceleration is rate of change of velocity.

[tex]\large {\boxed {a = \frac{v - u}{t} } }[/tex]

[tex]\large {\boxed {d = \frac{v + u}{2}~t } }[/tex]

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem !

This problem is about Kinematics.

We will solve it in the following way

Given:

distance traveled = d = 200.0 m

time taken = t = 20.6 s

Unknown:

average speed = v = ?

Solution:

[tex]v = \frac{d}{t}[/tex]

[tex]v = \frac{200}{20.6}[/tex]

[tex]v = \frac{1000}{103} ~ m/s[/tex]

Next we will change the units of this speed into km/h.

[tex]v = \frac{1000}{103} \times \frac{3600}{1000} ~ km/h[/tex]

[tex]v = \frac{3600}{103}~ km/h[/tex]

[tex]v \approx 35.0 ~ km/h[/tex]

The picture is a model of a nitrogen atom. What is incorrect about the atomic orbital arrangement of electrons in this model and how should they be arranged?

Answers

Answer: the picture does not represent the electron in the orbitals but the electrons in the principal energy levels.

Explanation:

I managed to find the picture with the model referred on your question.

To figure out what is wrong with the orbital arrangement you must do the electron distribuition for the nitrogen atom.

That starts with the atomic number. The atomic number for nitrogen is 7, that means that it has 7 protons and 7 electrons.

Orbitals only deal with electrons. So, you need to focus on the electrons and their distribution.

The electron distribution for 7 electrons is: 1s^2 2s^2 2p^3.

That means that two electrons are on the orbital 1s, two electrons are on the orbital 2s, two electrons are in one orbital 2p and one electron is in other orbital 2p (remember that there are three 2p orbitals, 2px, 2py and 2pz).Those are four orbitals, but the picture shows only two levels (circles around the nucleus).

The levels shown on the model of the picture do not represent orbitals but levels of principal energy ( the principal quantum number). So, the two electrons on the smaller circle are the electrons 1s^2, and the 5 electrons on the larger circle are the electrons on 2s^2 and 2p^3.

Then, what is wrong is that the picture does not represent the orbitals (which are 4, the 1s, the 2s and two 2p) but the principal energy levels (wich are two the number 1 and the number 2).


Two identical balls are thrown vertically upward. the second ball is thrown with an initial speed that is twice that of the first ball. how does the maximum height of the two balls compare? two identical balls are thrown vertically upward. the second ball is thrown with an initial speed that is twice that of the first ball. how does the maximum height of the two balls compare? the maximum height of the second ball is two times that of the first ball. the maximum heights of the two balls are equal. the maximum height of the second ball is four times that of the first ball. the maximum height of the second ball is 1.41 times that of the first ball. the maximum height of the second ball is eight times that of the first ball.

Answers

The motion of the ball on the vertical axis is an accelerated motion, with acceleration 
[tex]a=g=-9.81 m/s^2[/tex]
The following relationship holds for an uniformly accelerated motion:
[tex]2aS=v_f^2 - v_i^2[/tex]
where S is the distance covered, vf the final velocity and vi the initial velocity.

If we take the moment the ball reaches the maximum height (let's call this height h), then at this point of the motion the vertical velocity is zero:
[tex]v_f =0[/tex]
So we can rewrite the equation as
[tex]2(-9.81 m/s^2) h=-v_i^2[/tex]
from which we can isolate h
[tex]h= \frac{v_i^2}{19.62} [/tex] (1)

Now let's assume that [tex]v_i[/tex] is the initial velocity of the first ball. The second ball has an initial velocity that is twice the one of the first ball: [tex]2v_i[/tex]. So the maximum height of the second ball is
[tex]h= \frac{(2v_i)^2}{19.62}= \frac{4v_i^2}{19.62} [/tex] (2)

Which is 4 times the height we found in (1). Therefore, the maximum height of ball 2 is 4 times the maximum height of ball 1.

Hope this helps you=:O

~ TRUE BOSS

The correct option is (e). A longitudinal wave has all of the properties like speed, frequency, wavelength & amplitude.

Longitudinal waves are characterized by their unique properties, which include speed (a), frequency (b), wavelength (c), and amplitude (d). Here's a brief explanation of each property:

a. Speed (a): This is the rate at which the wave propagates through a medium. It is typically measured in meters per second (m/s) and depends on the properties of the medium, such as its density and elasticity.

b. Frequency (b): This is the number of complete cycles of the wave that pass a given point per unit time. It is measured in hertz (Hz) and is related to the pitch or tone of a sound wave, which is a type of longitudinal wave.

c. Wavelength (c): This is the distance between two consecutive points in the wave that are in phase, such as two adjacent peaks or two adjacent troughs. It is usually denoted by the Greek letter lambda [tex]\lambda[/tex] and is related to the frequency and speed of the wave by the equation [tex]\( v = f \lambda \)[/tex], where v is the speed, f is the frequency, and [tex]\( \lambda \)[/tex] is the wavelength.

d. Amplitude (d): This is the maximum displacement of a point on the wave from its rest position. It determines the loudness or intensity of a sound wave and is related to the energy carried by the wave.

Kennedy (November 22, 1963): President John F. Kennedy was fatally shot as his open limousine moved through a crowd of supporters in the streets of downtown Dallas. He was pronounced dead at a nearby hospital. Within an hour of his death, police had taken Lee Harvey Oswald into custody as their prime suspect. Two days later, as TV cameras rolled, Jack Ruby, a Texas nightclub owner, stepped through the crowd and shot Oswald. Though a government commission ruled Oswald responsible, Kennedy's death is still shrouded in mystery. To this day, many wonder who shot the President and why.The Exxon-Valdez Oil Spill (March 24, 1989): An oil tanker carrying 52 million gallons of oil ran aground at Bligh Reef in Alaska. More than 10 million gallons of oil spilled into Prince William Sound. The area was home to salmon, seals, sea otters, and sea birds. Hundreds of thousands of animals died in the spill. The remote location and sheer size of the spill made clean-up very difficult. The environmental effects are still felt today.

It meant, in theory, that older computer systems (like those used by banks, power companies, and the government) would stop working correctly at midnight on January 1, 2000. The fear was that the crash of computers would cause chaos as bank errors and power outages overtook the entire world. As part of the Y2K scare, companies worldwide upgraded their systems to avoid fallout, and no serious issues were reported.The Indian Ocean Earthquake and Tsunami (December 26, 2004): An undersea earthquake off the coast of Sumatra, Indonesia, caused a series of tsunamis (tidal waves) across Southeast Asia. The waves destroyed coastal villages in parts of Indonesia, Thailand, Sri Lanka, and India. Approximately 250,000 people were killed as a result of the earthquake and the tidal waves that followed.
