Answer:
Carrie’s net worth is -20700
Explanation:
Net Worth = Total Assets - Total Liabilities
Total Assets = $3500 + $1000 + $80 + $120 = $4700
Total Liabilities = $3000 + $500 + $12000 + $1200 + $500 + $8200 = $25400
$4700 - $25400 = -20700
So, her Net worth is -20700, in other words, her liabilities are greater than her assets
Carrie's net worth is calculated by subtracting her total liabilities ($22,200) from her total assets ($4,700). This results in a net worth of -$17,500.
Explanation:To determine Carrie's net worth, we first add up all her assets. This includes her car ($3,500), savings ($1,000), cash ($80), and earnings ($120), which adds up to a total of $4,700. We then add up her liabilities, which include her car loan ($3,000), credit card debt ($500), and the additional liabilities listed which total $22,200. Subtracting the total liabilities from the total assets ($4,700-$22,200), we find that Carrie's net worth is -$17,500.

Jackie Chan is filming a stunt for his new movie The Last Emperor of Des Moines. In the scene, Jackie is running across the top of a charter bus as it speeds down the highway directly into the path of an oncoming semi-truck. The bus is traveling at 20 m/s due west, Jackie is running 2 m/s due east, and the semi-truck is traveling 15 m/s due east. Describe Jackie's motion from the perspective of the driver of the semi-truck. Be sure to explain your reasoning.
Answer:
33m/s to the west
Explanation:
To describe the motion of Jackie you use the simple sum of velocities in a classical frame of reference. First of all you compute the speed of Jackie measured by an observer at rest. This velocity is the difference between the velocity of the bus and the velocity of Jackie because their motion are opposite.
[tex]v_J'=v_B-v_J[/tex]
v'J: velocity of Jackie as seen by an observer at rest
vJ: velocity of Jackie = 2m/s
vB: Bus velocity = 20m/s
By replacing you obtain:
[tex]v_J'=20m/s-2m/s[/tex] = 18m/s
Now, due to the semi-truck is traveling in the same direction of Jackie, you sum this velocities, in order to calculate the velocity of Jackie as seen by the driver in the semi-truck:
[tex]v_J''=v_J'+v_s=18m/s+15m/s=33m/s[/tex]
hence, the driver of semi-truck sees that Jackie is moving with a velocity of 33m/s to the west
From the semi-truck driver's perspective, Jackie Chan appears to be moving 3 m/s to the west, calculated using the principles of relative motion.
Explanation:The question involves analyzing Jackie Chan's motion from the perspective of the driver of the semi-truck in a scene from a fictitious movie. Here's how you can understand this scenario using basic physics principles:
The bus is moving at 20 m/s to the west.Jackie Chan is running at 2 m/s to the east, relative to the bus.The semi-truck is moving at 15 m/s to the east.From the semi-truck driver's perspective, we calculate relative motion to understand how fast Jackie appears to be moving. Since the semi-truck and Jackie are moving in the same direction (east), you subtract the speed of the bus from the sum of Jackie's speed and the truck's speed. The calculation is as follows:
Effective speed of Jackie from the semi-truck = (Jackie's speed + Truck's speed) - Bus's speed
Effective speed of Jackie = (2 m/s + 15 m/s) - 20 m/s = -3 m/s
This means, from the driver's perspective, Jackie appears to be moving 3 m/s to the west, opposite to the semi-truck's direction. The negative sign indicates the direction opposite to the positive convention, which is east in our initial setup.
What event led to the birth of the sun
Explanation:
A massive concentration of interstellar gas and dust created a molecular cloud that would form the sun's birthplace. Cold temperatures caused the gas to clump together, growing steadily denser, gradually to form the sun.
The birth of the sun and other stars is attributed to a process called stellar nucleosynthesis, which occurs within vast clouds of gas and dust known as nebulae.
What events led to it?The specific event that led to the birth of the sun is commonly referred to as "solar nebula hypothesis" or "solar nebula theory and is based on current understanding and observations of star formation and the early solar system.
The solar nebula hypothesis has it that :
About 4.6 billion years ago, a region of space within the Milky Way galaxy experienced the gravitational collapse of a massive molecular cloud. This molecular cloud was composed mostly of hydrogen and helium, along with trace amounts of other elements.
The gravitational collapse led to an increase in density and temperature at the center of the cloud, resulting in the formation of a protostar.
The protostar is the early stage of the sun, where nuclear fusion reactions have not yet initiated.

What is air resistance a form of? Define air resistance
Answer:
By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.
Explanation:
Air resistance is a form of frictional force that slows down the motion of objects as they travel through the air.
Explanation:In the subject of physics, air resistance is a form of frictional force that slows down the motion of objects as they travel through the air. It is caused by the interaction between the moving object and the molecules in the air.
For example, when an object falls through the air, air resistance acts in the opposite direction of its motion, causing it to fall slower than it would in a vacuum. Similarly, when a car moves forward, it pushes the air in its direction of motion, which creates air resistance that opposes the car's movement.

What is magnetic field of earth?Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core
The inner core (which is solid) is the hottest layer of the earth. It, therefore, contributes to heating up the outer core. The outer core is liquid and rotation of the earth (Coriolis effect) causes the molten rocks to swirl like a tornado.
Because the outer core is mostly made of metals, that have lost electrons and hence charged (due to the enormous heat), the swilring effect causing an electric effect.
This consequently causes the dynamo effect that creates a magnetic field. This magnetic field covers the earth and protects it from harmful radiation from the solar storms.

in what state of matter can conduction occur
Conduction can occur in all states of matter, including solid, liquid, gas, and plasma. This process involves the transfer of heat through stationary matter by direct physical contact, a result of the thermal motion of atoms and molecules.
Explanation:Conduction, which in the context of physics refers to heat transfer through stationary matter by physical contact, can occur in all three common states of matter - solids, liquids, and gases. This transfer is due to the thermal motion of atoms and molecules at any temperature above absolute zero. For instance, heat is transferred between an electric burner of a stove and the bottom of a pan by conduction. This is because the energetic motion of particles in one area spreads to other regions, and even to adjacent objects in close contact.
In the solid state, conduction is quite efficient because the particles are closely packed and can readily transfer energy to their neighbors. In liquids and gases, the particles are more spread out, but conduction still occurs, albeit at a slower pace. A fourth state of matter, plasma, also exists and conductive heat transfer occurs within this state because it contains appreciable numbers of electrically-charged particles.

Which of the following best represents a neutralization reaction?
a) acid + salt > base + water
b) acid + base > salt + water
c) water + salt > acid + base
d) acid + water > base + salt
Answer:
It’s B
Explanation:
Hope it helps
The equation that best represents a neutralization reaction is acid + base > salt + water. The correct option is b.
An acid and a base combine to generate a salt and water in a neutralization process.
Acids are chemicals that emit hydrogen ions (H+) in water, whereas bases emit hydroxide ions (OH-) in water.
When an acid and a base react, the acid's hydrogen ions join with the base's hydroxide ions to generate water (H2O). Simultaneously, the leftover ions from the acid and base combine to create a salt.
Thus, option b) acid + base > salt + water appropriately describes a neutralization reaction in which an acid and a base combine to form a salt and water.

una bala de 20 g choca con un fango como se muestra en la figura y penetra una distancia de 6 cm antes de detenerse. calcule la fuerza de frenado f si la velocidad de entrada fue de 80m/s
Answer:
A 20g bullet collides with a mud as shown in the figure and penetrates a distance of 6cm before stopping. calculate the braking force f if the input speed was 80m/s
Explanation:
Given that,
A bullet of mass
M = 20g = 0.02kg
The bullet is fired into a mud initially at rest
The bullet penetrate a distance of 6cm in the mud
S = 6cm = 0.06m
The input velocity into the mud is 80m/s, this implies that, the initial velocity is 80m/s
U = 80m/s
So, the bullet stop after a distance of 6cm, so the final velocity is 0m/s
V = 0m/s
So, we need to find the braking force
Breaking force (F) is given as
F = ma
Where m is mass and 'a' is deceleration
So, we need to find the deceleration, using equation of motion
V² = U² + 2as
0² = 80² + 2 × a × 0.06
0 = 6400 + 0.12a
0.12a = -6400
a = -6400 / 0.12
a = - 53,333.33 m/s²
So, the negative sign shows that the bullet is decelerating
So, a = 53,333.33 m/s²
So, breaking force
F = ma
F = 0.02 × 53,333.33
F = 1066.67 N
The breaking force is 1066.67 N
In spanish
Dado que,
Una bala de masa
M = 20 g = 0.02 kg
La bala se dispara en un lodo inicialmente en reposo
La bala penetra una distancia de 6 cm en el barro.
S = 6 cm = 0.06 m
La velocidad de entrada al lodo es de 80 m / s, esto implica que la velocidad inicial es de 80 m / s
U = 80 m / s
Entonces, la bala se detiene después de una distancia de 6 cm, por lo que la velocidad final es de 0 m / s
V = 0 m / s
Entonces, necesitamos encontrar la fuerza de frenado
La fuerza de ruptura (F) se da como
F = ma
Donde m es masa y 'a' es desaceleración
Entonces, necesitamos encontrar la desaceleración, usando la ecuación de movimiento
V² = U² + 2as
0² = 80² + 2 × a × 0.06
0 = 6400 + 0.12a
0.12a = -6400
a = -6400 / 0.12
a = - 53,333.33 m / s²
Entonces, el signo negativo muestra que la bala se está desacelerando
Entonces, a = 53,333.33 m / s²
Entonces, fuerza de ruptura
F = ma
F = 0.02 × 53,333.33
F = 1066.67 N
La fuerza de ruptura es 1066.67 N

How does Mr. Anderson define solubility in the video?
2. What is the solubility of talc in 100 mL of 25 °C water? Explain why talc has this solubility. 3. Describe how increasing temperature affects the solubility of solid and liquid solutes.
4. Why is there less oxygen in ocean water near the equator than in water at higher latitudes? 5. A factory discharges clean, warm water into a nearby stream. Fish keep dying in this part of stream. Explain why.
Solubility is the capacity of a solute to dissolve in a solvent. Warm temperatures often increase the solubility of solids and liquids, but reduce the solubility of gases like oxygen. This is why warmer ocean waters and artificially warmed waters can contain less oxygen, potentially leading to negative effects on aquatic life.
Explanation:In the video, Mr. Anderson defines solubility as the maximum amount of solute that can be dissolved in a specific amount of solvent at a given temperature. For instance, the solubility of talc in water at 25 °C is fundamentally none because talc is a mineral compound that does not interact with water molecules to any significant extent. Talc particles will simply settle to the bottom rather than dissolve.
The solubility of both solid and liquid solutes usually increases with temperature, although there are exceptions. The increase in kinetic energy that comes with higher temperatures allows solute particles to break apart more easily and become dispersed throughout the solvent.
Ocean water near the equator contains less dissolved oxygen than water at higher latitudes due to the effect of temperature on gas solubility. The higher temperatures near the equator decrease the solubility of oxygen, leading to lower concentrations. In the scenario of fish dying in the part of a stream into which a factory discharges clean, warm water, the likely cause is a decrease in the solubility of oxygen due to the temperature rise, leading to insufficient oxygen for the fish to survive.

The potential energy an object has due to it position Is called _______ potential energy
Final answer:
The potential energy an object has due to its position is called gravitational potential energy. It is related to an object's height relative to a gravitational source, typically Earth, and increases with elevation. Another form, elastic potential energy, is stored in stretched or compressed objects.
Explanation:
The potential energy an object has due to its position is called gravitational potential energy. This type of energy is a function of an object's position relative to a source of gravitational force, usually Earth for problems encountered in middle and high school physics. Gravitational potential energy increases as the height of an object increases relative to a reference point, commonly ground level. For example, a book placed on a higher shelf has more gravitational potential energy compared to when it is on a lower shelf because it has the potential to do more work if it falls.
Another form of potential energy relevant in physics is elastic potential energy, which is stored in objects like springs and rubber bands when they are stretched or compressed. This energy is a function of the displacement and the stiffness of the object, as described by Hooke's Law.

Based on Kepler's third law of motion, the relationship between a planet's orbital velocity and its distance from the sun is
D)The greater the distance, the slower the orbital velocity.
Explanation:
A planet's orbital speed changes, depending on how far it is from the Sun. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.Kepler's first law - sometimes referred to as the law of ellipses - explains that planets are orbiting the sun in a path described as an ellipse. The resulting shape will be an ellipse. An ellipse is a special curve in which the sum of the distances from every point on the curve to two other points is a constant.Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.Kepler's Third Law. “The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit” That's Kepler's third law. In other words, if you square the 'year' of each planet, and divide it by the cube of its distance to the Sun, you get the same number, for all planetsAnswer:
