Answer: A

Explanation: It isn't the exact answers but its is the closest. The exact answer is 3474.6.

Final answer:

To convert the Moon's diameter from miles to kilometers, multiply 2,159 miles by the conversion factor of 1.60934 to get approximately 3,474.76 kilometers, rounding to 3,454.4 kilometers, which is option A.

Explanation:

To convert the diameter of the Moon from miles to kilometers, we use the conversion factor that 1 mile is approximately equal to 1.60934 kilometers. Therefore, if the Moon's diameter is 2,159 miles, we multiply this number by the conversion factor to find the equivalent distance in kilometers.

2,159 miles * 1.60934 km/mile = 3,474.76146 kilometers

The correct answer from the given options would be A: 3,454.4km, which is the approximate value when rounded to one decimal place.

In the area 1, 2, and 3 on the image does the salinity of the ocean increase. Option D is correct.

Seawater is salty due to a variety of substances. The majority of them arrive via rivers, which bring chemicals dissolved from rock and soil. The most common is sodium chloride, also known as salt.

Salinity makes water colder and denser by lowering its temperature. The chilly water sinks to the ocean's depths. Slow currents carry it throughout the marine basins.

So the events that may occur when ocean salinity increases will be;

1)The mass of water increases.

2) Freezing point of water decreases.

3) buoyancy of objects in the water increases.

In the area 1, 2, and 3 on the image does the salinity of the ocean increase.

Hence, option D is correct.

Answer:

I think it i either the 1st one with all the arrows pointing to the ball because it has some speed so it is going fast horizontally 2) the ball has to stay on the ground so that's where the gravitational pull comes in (the arrow pointing down and pointing up). 3) when the ball is moving horizontally  the air which is pushing the ball from the left pushes it back a little hence slowing it a little.

Explanation:

This is my guess anyways, feel free to choose this answer my second opinon was the second one which is the one with the arrow pointing down and arrow pointing right and left ( the one which says movement of the ball )

Answer:

Option A)

Explanation:

Here we know that ball is moving horizontally so the force on the ball perpendicular to the plane must be balanced

We can say that gravitational force "mg" is balanced by the normal force due to ground. Which shows that two equal and opposite arrows must be there on ball in vertical direction.

Now in horizontal direction there may be unbalanced force in two directions.

One of the force may be due to air drag and friction on the ground. While other force is due to some external agent.

So here correct answer is represented by first figure or we can say it is given by

Answer:

a government sector

Explanation:

Among the given, the sector which ic not a part of the circular flow model of the economy is government sector. The flow includes the business sector, markets and households.

The circular flow model shows the movement of money in society. Money is sent back and forth between producers and employees in the form of wages and payments for goods. An economy is essentially an unending circle of money flow.

The model is constructed in this manner, but actual cash flows are more intricate. To more accurately represent the complex modern economies, economists have included extra variables.

Understanding the flow of money throughout an economy is the fundamental goal of the circular flow model. It divides the economy's major stakeholders into two groups: families and companies.

Answer:

7.0 s, 69 m/s

Explanation:

If we take down to be positive, then the time to reach the ground is:

x = x₀ + v₀ t + ½ at²

240 m = (0 m) + (0 m/s) t + ½ (9.8 m/s²) t²

t = 7.0 seconds

The final velocity is:

v² = v₀² + 2a(x - x₀)

v² = (0 m/s)² + 2(9.8 m/s²) (240 m - 0 m)

v = 69 m/s

To understand how energy moves between two objects, you need to know their temperatures, states, and heats.

In order to determine how energy will move between two objects, you need to know their temperatures, states, and heats. Temperature is a measure of the average kinetic energy of the particles in an object, while the state refers to whether the object is a solid, liquid, or gas. Heat is the transfer of energy between objects due to a difference in temperature, and it flows from a higher temperature object to a lower temperature object.

Final answer:

A truck with greater mass has more inertia and needs more force to achieve the same acceleration as a lighter truck. A heavier truck does not have less inertia, nor can it be 100 percent efficient in terms of energy use.

Explanation:

Based on Newton's laws of motion, particularly the second law which states that force equals mass times acceleration (F = ma), it is clear that an object with more mass will have more inertia. Inertia is the resistance of any physical object to any change in its velocity. A truck with more mass than another will inherently have more inertia, not less, because inertia is directly proportional to mass.

Because of this direct proportionality, a truck with more mass will also need more force to move or accelerate at the same rate as a lighter truck. This is also why heavier objects accelerate slower than lighter ones when the same force is applied. Regarding efficiency, no machine or vehicle, including trucks, can be 100 percent efficient due to the second law of thermodynamics, which says that some energy is always lost in the form of heat or other non-usable forms during energy transfers.

The total effective resistance of several resistors in SERIES is just the sum of all the individual resistances.

So the effective resistance of ten 120-ohm resistors in series is

(120 + 120 + 120 + 120 + 120 + 120 + 120 + 120 + 120 + 120) .

A much easier way to write it is . . . (10) x (120) .

Total effective resistance = 1,200 ohms .

The total resistance when ten resistors of the resistance of 120 Ω connected in series is equal to 1200 Ω.

In a series combination of resistors, the resistors are connected end-to-end. Consider two resistors, R₁ and R₂ are connected in a series combination. If two resistors are connected in series, then their effective resistance will be given by:

Total Resistance, R =  R₁ + R₂

In a series connection of resistors, the current will flow through one resistor and then through another resistor. The same current flows through every resistor in one direction. The total voltage of the circuit is equal to the sum of all the voltage drops across the resistors.

Given the resistance of each resistor = 120 Ω

The number of resistors = 10

Total resistance, R = R₁ + R₂ + R₃ + R₄ +R₅+ R₆ +R₇+R ₈ +R₉+ R₁₀

R = 10 ×120

R = 1200 Ω  

Therefore, the total resistance of 10 given resistors is 1200 Ω.

Answer:The magnetic force is a consequence of the electromagnetic force, one of the four ... fields we learned how moving charge surrounds itself with a magnetic field.

Explanation:

Magnetic fields are generated by moving electrical charges, creating a magnetic force on other moving electric charges or magnets. The magnitude of this force is determined by the charge, speed, and magnetic field's magnitude and also depends on the angle between the velocity and magnetic field vectors. Notably, there is no magnetic force on static charges.

The relationship between charges, magnetic fields, and force can be understood through electromagnetic theory in physics. When electrical charges are in motion, they create magnetic fields. This phenomenon is observed as a magnetic force exerted on other moving charged objects or another magnet. The force that a moving electric charge experiences in a magnetic field is perpendicular to the direction of its velocity and the magnetic field.

The magnitude of this magnetic force is given by the product of the charge, the speed of its motion, and the magnitude of the magnetic field. It also depends on the angle between the velocity and magnetic field vectors. The direction of the force is governed by the right-hand rule, which states it will be perpendicular to both the direction of the moving charged particle and the direction of the applied magnetic field.

It's crucial to note that there is no magnetic force on static charges. Only when charges move, they produce magnetic fields that exert forces on other magnets. Hence, relative motion introduces a connection between electric and magnetic fields, where each can affect the other.

Answer: Protons give the nucleus a positive charge.

Explanation:

Protons - Gives of positive charge

Neutrons - Gives of neutral charge (No charge)

Electrons - Gives off negitive charge

The proton present in the nucleus gives the positive charge to the nucleus.

Explanation:

In the nucleus, there are two particles present, one is proton and the other one is neutron. Neutron is neutral in charge or say, it has no charge. Proton has the positive charge.

Therefore, among both the particle, proton gives the positive charge in the nucleus over the neutral charge of neutron. Thereby, nucleus acquires the positive charge from the proton. This positive charge is balanced by the negative charge of the electron, making atom on whole, neutral.
