When observing two charged objects, if they repel each other, it implies that they have the same type of charge. In this case, ball 1 has a larger charge than ball 2.

Based on this information, we can conclude that the magnitude of the electric force on ball 1 is greater than the magnitude of the electric force on ball 2. The magnitude of the electric force between two charged objects depends on the charges of the objects and the distance between them. According to Coulomb's law, the electric force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Since ball 1 has a larger charge than ball 2, the product of the charges in the equation for electric force will be larger for ball 1. As a result, the magnitude of the electric force on ball 1 will be greater compared to the magnitude of the electric force on ball 2.

To produce 180 more tanks starting from point "b" (420 tanks and 800 bushels of corn), the society would need to increase its corn production by 540 bushels.

In order to produce more tanks, the society needs to allocate additional resources to tank production. Let's assume that each tank requires 3 bushels of corn as raw material. Since the society wants to produce 180 more tanks, it would need an additional 180 tanks * 3 bushels per tank = 540 bushels of corn.

To meet this increased demand for corn, the society must increase its corn production. Starting from point "b" with 800 bushels of corn, they would need to produce an additional 540 bushels of corn to reach the required total of 1,340 bushels (800 + 540).

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When the crate falls downward through the snow, it experiences two forces: the gravitational force and the upward force.

Initially, when the crate starts to move downward through the snow, its speed increases and its acceleration is downward. This means that the net force acting on the crate is downward and is greater than the upward force exerted by the snow. The net force is the difference between the gravitational force (weight) and the upward force from the snow.

However, as the crate moves deeper into the snow and its speed starts to decrease, the upward force exerted by the snow becomes stronger. Eventually, when the crate's speed becomes zero (it comes to a stop), the upward force from the snow becomes equal in magnitude to the gravitational force.

-Initially, the magnitude of the upward force exerted by the snow is less than the magnitude of the gravitational force.

-As the crate slows down, the magnitude of the upward force increases.

-When the crate comes to a stop, the magnitude of the upward force                becomes equal to the magnitude of the gravitational force.

The magnitude of the friction in newtons is 10 N.

The magnitude of the friction force can be calculated using the formula

F_friction = μ * F_normal, where μ is the coefficient of friction and F_normal is the normal force.

In this case, since the block is on a horizontal surface, the normal force is equal to the weight of the block, which can be calculated as

F_weight = m * g, where m is the mass of the block and g is the acceleration due to gravity (approximately 9.8 m/s^2).

Thus, F_normal = 5 kg * 9.8 m/s^2 = 49 N.

Given that the magnitude of the push force is 25 N and the block accelerates with a magnitude of 2 m/s^2, we can use Newton's second law, F_net = m * a, to find the net force acting on the block. Rearranging the equation, we get

F_net = m * a = 5 kg * 2 m/s^2 = 10 N.

Since the friction force acts in the opposite direction of the push force, the magnitude of the friction force is equal to the magnitude of the net force, which is 10 N. Therefore, the magnitude of the friction in newtons is 10 N.

In this problem, the total work done on the block in the absence of friction is equal to the change in its potential energy, mgh. After the block reaches point P, it still has some kinetic energy, but this energy is dissipated through friction.

The coefficient of friction between the block and the horizontal surface is 0.20. The work done on the block by friction is equal to the force of friction times the distance the block slides. The work done by friction is equal to the initial kinetic energy of the block, which is equal to its potential energy at the start, minus its potential energy at point P, multiplied by -1.

So, the distance that the block slides on the horizontal surface is: Where m is the mass of the block, g is the acceleration due to gravity, h is the height of the slope, hP is the height of the bottom of the slope, f is the coefficient of friction, and k is the spring constant.

Explanation:

1. Volcanoes occur at specific locations on the Earth's surface, mainly along tectonic plate boundaries.

2. Volcanism is the result of geological processes that occur inside the Earth.

3. Scientists use various methods to monitor volcanoes and predict eruptions. They use seismometers to detect earthquakes, which can indicate the movement of magma beneath the surface.

4. Volcanoes can also occur in other tectonic settings, such as within continental plates or on mid-ocean ridges.

Where volcanoes occur:

Volcanoes occur at specific locations on the Earth's surface, mainly along tectonic plate boundaries. There are three main types of plate boundaries: divergent, convergent, and transform. Volcanoes typically occur at divergent and convergent plate boundaries. At divergent boundaries, magma rises up to the surface as the plates move away from each other, forming fissures or vents that release lava and ash. At convergent boundaries, one plate subducts or goes beneath the other, and the magma rises up through the crust and erupts on the surface. There are also volcanic hotspots, which occur when a plume of hot magma rises from deep within the Earth's mantle and breaks through the crust to form a volcano.

Why volcanoes occur:

Volcanism is the result of geological processes that occur inside the Earth. The Earth's crust is made up of tectonic plates that move and interact with each other. When plates move apart at divergent boundaries, the underlying mantle is partially melted, and magma rises up to the surface. When plates collide at convergent boundaries, the denser oceanic plate is forced beneath the lighter continental plate in a process known as subduction. As the subducting plate sinks deeper into the Earth, it heats up and melts, creating magma that rises to the surface to form volcanoes. Volcanic hotspots are thought to be caused by a plume of hot magma rising from deep within the Earth's mantle and melting the crust above it.

How scientists can predict volcanic eruptions:

Scientists use various methods to monitor volcanoes and predict eruptions. They use seismometers to detect earthquakes, which can indicate the movement of magma beneath the surface. They also monitor gas emissions from the volcano, as changes in the types and amounts of gas can indicate an impending eruption. Ground deformation, measured using GPS and other instruments, can also provide clues about the movement of magma beneath the surface. Scientists use this data to create models of the volcano's behavior and predict when an eruption is likely to occur. They can then issue warnings and evacuation orders to minimize the impact of the eruption.

Outline the function of volcanoes in other tectonic settings:

Volcanoes can also occur in other tectonic settings, such as within continental plates or on mid-ocean ridges. In these settings, volcanoes can create new land, add nutrients to the soil, and provide geothermal energy. Volcanic eruptions can also release gases that affect the Earth's climate, such as carbon dioxide and sulfur dioxide. Over time, volcanic activity can change the landscape and shape the Earth's surface. For example, the Hawaiian Islands were formed by a volcanic hotspot that created a series of volcanic islands as the Pacific plate moved over it.

Tom's 2019 income tax liability is $110. The correct answer is option e. None of these choices are correct.

Tom's income tax liability can be calculated as follows:

First, we determine Tom's total income by adding his unearned income and income from mowing lawns:

Total income = Unearned income + Lawn mowing income

Total income = $3,400 + $300

Total income = $3,700

Next, we calculate Tom's taxable income by subtracting the threshold for taxing unearned income:

Taxable income = Total income - Threshold for taxing unearned income

Taxable income = $3,700 - $2,600

Taxable income = $1,100

Now, we can calculate Tom's income tax liability by applying the tax rate to his taxable income:

Income tax liability = Taxable income * Tax rate

Income tax liability = $1,100 * 10% (since the first $2,600 of net unearned income is taxed at 10%)

Income tax liability = $110

Option d, 1.12 x \(10^{-19}\)J is the energy of a photon of light if the wavelength of the light wave is 4.65 x \(10^{-7}\)m.

Energy (E) of a photon of light is given by the formula:

E=hf

where, h = Planck's constant and f = frequency of light. But, we are given the wavelength of light, λ = 4.65 x \(10^{-7}\)m.

So, we know that

c = fλ

where, c is the speed of light in a vacuum. Rearranging this formula to solve for f,

f = c/λ

Putting this into the energy formula gives:

E = hf = hc/λ

We know that Planck's constant is h = 6.626 x \(10^{-34}\)J.s and the speed of light in a vacuum is c = 3.00 x \(10^{8}\)m/s. So,

E = hc/λ = (6.626 x \(10^{-34}\)J.s)(3.00 x \(10^{8}\)m/s)/(4.65 x \(10^{-7}\)m) = 4.28 x \(10^{-19}\)J

Therefore, the energy of a photon of light if the wavelength of the light wave is 4.65 x \(10^{-7}\)m is 4.28 x \(10^{-19}\)J which is option d.
