The mass of the asteroid is C. 1.2 x \(10^{12}\) Kg

To find the mass of the other asteroid, we can rearrange the equation for the gravitational force between two objects:

F = (G * m1 * m2) / \(r^{2}\)

where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two asteroids, and r is the distance between them.

Given that the distance between the asteroids is 75000 m, the force of gravity between them is 1.14 N, and one asteroid has a mass of 8 x \(10^{7}\) kg, we can substitute these values into the equation and solve for the mass of the other asteroid (m2):

1.14 N = (6.67430 × \(10^{-11}\) N \(m^{2}\)/\(Kg^{2}\) * 8 x \(10^{7}\) kg * \(m2\)) / \((75000 m)^{2}\)

Simplifying and solving the equation, we find that the mass of the other asteroid (m2) is approximately 1.2 x \(10^{12}\) kg. Therefore, Option C is correct.

Explanation: The correct option is:

Both fossil fuels and wind energy can be used to produce electricity. However, burning fossil fuels does pollute the atmosphere, while using Earth's wind does not. Both fossil fuels and wind energy contribute to climate change, but the use of fossil fuels is much more damaging to the environment than the use of wind power.

Fossil fuels are non-renewable sources of energy that are formed over millions of years by the decomposition of organic matter. They release harmful greenhouse gases when burned, contributing to climate change. In contrast, wind energy is a renewable source of energy that uses turbines to harvest the power of wind. Wind energy does not produce any emissions, making it an environmentally friendly alternative to fossil fuels. While wind turbines can have some impacts on wildlife and habitats, the impact is much less severe than the effects of fossil fuel extraction and burning.

Added Part: Fossil fuels are non-renewable sources of energy that are derived from the remains of plants and animals that died millions of years ago. These sources include coal, oil, and natural gas. Wind energy, on the other hand, is a renewable source of energy that is generated by the kinetic energy of wind.

Here are some comparisons between fossil fuels and wind energy:

Environmental Impact: Fossil fuels have a significant negative impact on the environment. Burning fossil fuels produces greenhouse gases that contribute to climate change. The extraction of fossil fuels also has negative impacts on the air, water, and soil. Wind energy, however, has a very small environmental footprint. Wind turbines do not produce any emissions and do not require any water to generate electricity.

Energy Availability: Fossil fuels are abundant and have been the primary source of energy for decades. On the other hand, wind energy is a relatively new source of energy and the technology is still developing. However, the availability of wind energy is significant, as wind is a renewable source that is constantly available.

Sustainability: Fossil fuels are non-renewable, which means they will eventually run out. As the demand for energy continues to increase, the availability of fossil fuels will decrease. Wind energy is a renewable source of energy that will never run out.

Here are some pros and cons of both fossil fuels and wind energy:

Fossil Fuels:

Pros:

Reliable source of energy

High energy density

Large global infrastructure

Cons:

Non-renewable source of energy

Significant environmental impact

Price instability

Wind Energy:

Pros:

Renewable source of energy

Small environmental footprint

Low operating costs

Cons:

High initial costs for building wind turbines

Wind is an inconsistent source of energy

To graph the function g(x) = f(-x), you can start with the graph of f(x) and then reflect it about the y-axis.

To find the graph of the function g(x) = f(-x), we can start with the graph of the function f(x) and then reflect it about the y-axis.

If the graph of f(x) is symmetric with respect to the y-axis, meaning it is unchanged when reflected, then g(x) = f(-x) will have the same graph as f(x).

However, if the graph of f(x) is not symmetric with respect to the y-axis, then g(x) = f(-x) will be a reflection of f(x) about the y-axis.

In either case, the resulting graph of g(x) = f(-x) will be symmetric with respect to the y-axis.

The ion with a +3 charge, 28 electrons, and an atomic mass of 71 is the aluminum ion (\(Al^{3+}\)).

Aluminum (Al) typically has an atomic number of 13, which means it has 13 protons and 13 electrons in its neutral state. However, in the given ion, \(Al^{3+}\), the ion has lost three electrons, resulting in a +3 charge. This means that the ion now has 13 protons and only 10 electrons remaining, giving it a net positive charge of +3.

The atomic mass of aluminum is 26.98 atomic mass units (amu). The given ion has an atomic mass of 71 amu, which suggests that the ion has gained additional particles. In this case, the ion has also gained three neutrons, resulting in a higher atomic mass.

The total number of particles (protons, neutrons, and electrons) in the ion can be calculated by adding the number of protons (13) and the number of neutrons (3), which equals 16. Since the ion has a net charge of +3, it only contains 10 electrons.

In summary, the ion with a +3 charge, 28 electrons, and an atomic mass of 71 is the aluminum ion (\(Al^{3+}\)), which has 13 protons, 10 electrons, and 3 neutrons.

Types of luminous flames:

1. Yellow Luminous Flame

2. Smoky Luminous Flame

3. Orange Luminous Flame

4. Blue Luminous Flame

Luminous flames are characterized by their visible glow, which is caused by the incomplete combustion of fuel. The presence of soot particles in the flame causes the emission of light. There are different types of luminous flames, which can be classified based on their fuel composition and burning conditions. Here are some common types of luminous flames:

1. Yellow Luminous Flame: This is the most common type of luminous flame, often seen in open fires, candles, and gas stoves. It appears yellow due to the presence of soot particles in the flame. Yellow flames indicate incomplete combustion of hydrocarbon fuels, such as methane, propane, or natural gas. The high carbon content in these fuels leads to the formation of soot, which emits visible light.

2. Smoky Luminous Flame: This type of flame is characterized by a significant amount of black smoke and soot production. It is commonly observed in poorly adjusted or malfunctioning burners or engines. The excessive presence of unburned fuel in the flame results in incomplete combustion and the emission of dark smoke particles.

3. Orange Luminous Flame: An orange flame indicates a higher combustion temperature compared to a yellow flame. It is often seen in more efficient burners or when burning fuels with a higher carbon content, such as oil or diesel. The higher temperature helps in burning more of the carbon particles, reducing the amount of soot and making the flame appear less yellow.

4. Blue Luminous Flame: A blue flame is typically associated with complete combustion. It indicates efficient burning of fuel, resulting in minimal soot formation. Blue flames are commonly observed in gas burners or Bunsen burners. The blue color is a result of the combustion of gases, such as methane, in the presence of sufficient oxygen.

It's important to note that the luminosity of a flame can vary depending on factors such as fuel-air mixture, combustion temperature, and the presence of impurities. Achieving complete combustion and minimizing the production of soot is desirable for efficient and cleaner burning processes.

Answer:

A formula car is a single seat, open cockpit, open wheel racing car with substantial front and rear wings and an engine positioned behind the driver intended to be used in competition.

Explanation:

Molarity is the ratio between the amount of substance in the solute, measured in mol (n1), and the volume of the solution in liters (V). This concentration is measured in mol per liter (mol/L).

The mathematical formula used to calculate this concentration is given by:

M = n1/V

First, we need to transform 0.589 g of MgI2 into moles. For this, we use the molar mass of MgI2.

Molar mass of Mg = 24.305 g/mol

molar mass of I = 126.90 g/mol

MgI2 = (1*24.305) + (2*126.90) = 278.1 g/mol

Now we use the following formula to transform grams to moles: moles = mass/molar mass

mass = 0.589 g

molar mass = 278.1 g/mol

moles = 0.589/278.1

moles = 2.1 x 10^-3

Now let's calculate the molarity:

n1 = 2.1 x 10^-3 moles

V = 75 mL = 0.075 L

M = 2.1 x 10^-3 /0.075

M = 0.0282 M

Answer:

Explanation:

The protein comprises of two 60-kD polypeptides and two 40-kD polypeptides. Each one of the 40-kD chains has a disulfide-bond which is directly bonded to a 60-kD chain.

The 100-kD units attach noncovalently to produce a protein with a molecular mass of 200 kD. The interaction among the different subunits in the protein is not affected by the Gel filtration chromatography.

Hence, the protein seems to be 200 kD in size. When SDS-PAGE takes place samples are being subjected to heat and therefore undergoing denaturation conditions. The aftermath effect of this causes disorganization in the 100 kD units.

However, the reducing agent (BME) main task is the reduction of disulfide bonds in a protein.

It implies that BME is responsible for the reduction between the R1-S-S-R2 bond between 40 kD and 60 kD to R1-SH and R2-SH, resulting in seperate proteins.
