The free enterprise system allows the citizen to own and operate a private business for profit.
The basic principles of a free enterprise system were laid out by Scottish philosopher Adam Smith in an influential book published in 1776: An Inquiry into the Nature and Causes of the Wealth of Nations. The Nobel-prize winning 20th century economist Milton Friedman said of Adam Smith, "The key insight of Adam Smith's Wealth of Nations is misleadingly simple: If an exchange between two parties is voluntary, it will not take place unless both believe they will benefit from it." Smith argued for such voluntary exchanges within a free market system. He labeled the government-manipulated economic system that was prevailing in his day as "mercantilism," a system in which governments specifically authorized some merchants as the official agents of commerce (rather than endorsing free enterprise). The mercantilist system also viewed wealth as though there were a fixed amount of it available in the world, represented by precious metals such as gold and silver, and that nations were in competition over who got more of that fixed amount of world wealth. Smith saw that wealth was something that could be created and increased through voluntary exchange and free enterprise. Smith's ideas formed the basis for what we have come to know as capitalism.

Suppose these waves represent the sound of a siren on a passing ambulance. Which wave represents the sound of the siren after it has passed you? Explain your answer.
The wave A has a higher frequency and wave B has a lower frequency.
I REALLY need help. Please.
Answer:
The correct answer is "wave B has a lower frequency."
Explanation:
The Doppler effect is defined as the change in apparent frequency of a wave produced by the relative movement of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave movement when the sender and the receiver, or observer, move relative to each other.
This is the effect that occurs in this case. And it is explained as follows: When the ambulance approaches the observer, the wave "compresses", that is, the wavelength is short, the frequency high and, therefore, the tone of the perceived sound will be sharp. On the other hand, when the ambulance moves away from the observer, the wave "decompresses", that is, the wavelength is long and the frequency low.
Then the correct answer is "wave B has a lower frequency."

C) 1 to 2
D) there is no pattern that indicates stability in the nucleus
the correct answer is the letter A)1 to 1
The nuclei of atoms that are the most stable have proton to neutron ratios of 1:1. Thus, the correct option for this question is A.
What is the nucleus of an atom?The nucleus of an atom may be defined as the center of any atom that significantly consists of protons and neutrons. Due to the positive charge on protons and neutral charge on neutrons, the nucleus of an atom is found to be positively charged.
In the structure of any atom, the number of protons and neutrons in the nucleus of an atom remains equal most of the time.
But when it comes to isotopes, when atoms of different elements have the same atomic number but different mass number, the number of neutrons significantly changes.
Therefore, the nuclei of atoms that are the most stable have proton to neutron ratios of 1:1. Thus, the correct option for this question is A.

A student measured the pH of four solutions. Which pH indicates the highest hydronium ion concentration? 3.2 7.0 9.1 12.4
Answer: 3.2
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
[tex]pH=-\log [H_3O^+][/tex]
[tex]pH=log\frac {1}{H_3O^+}[/tex]
Thus as pH and [tex]H^+[/tex] are inversely related, a solution having lower pH will have more amount of [tex]H^+[/tex] concentration. And a solution having more pH will have less amount of [tex]H^+[/tex] concentration.
Thus the solution with lowest pH of 3.2 will have highest hydronium ion concentration.

Particles of charge +75, +48, and -85μC are placed in a line. The center one is 0.35 m from each of the others. Calculate the net force on each charge due to the other two.
The net force on each charge due to the other two can be calculated using Coulomb's Law. The net force on the +75μC charge is 0.263 N in the positive x-direction, and the net force on the -85μC charge is -0.263 N in the negative x-direction.
Explanation:To calculate the net force on each charge due to the other two, we can use the formula for the electric force between two charges: F = k x q1 x q2 / r2, where F is the net force, k is the Coulomb's constant (9 x 109 N m2/C2), q1 and q2 are the charges, and r is the distance between the charges.
Let's calculate the net force on the +75μC charge due to the +48μC and -85μC charges. The distance between the +75μC charge and the +48μC charge is 0.35 m. Substituting these values into the formula, we get F1 = (9 x 109 N m2/C2) x (75 x 10-6 C) x (48 x 10-6 C) / (0.35 m)2 = 0.263 N.
The net force on the -85μC charge due to the +75μC and +48μC charges is the same as the net force on the +75μC charge, but in the opposite direction, giving us: F2 = -0.263 N.
Therefore, the net force on the +75μC charge is 0.263 N in the positive x-direction, and the net force on the -85μC charge is -0.263 N in the negative x-direction.

What is the difference between Earth's magnetic and geographic poles? How do navigators take advantage of this?
The difference between the positions of these two poles when viewed at different locations is defined as the magnetic declination which allows these angles for navigators to determine their true geographic position.
What is Magnetic declination?Magnetic declination is also known as magnetic variation. It is the angle on the horizontal plane between magnetic north and true north which varies depending on the position on the Earth's surface and changes over time.
Declination is positive when the angle is east of true north and negative when it is west. It changes over time and with place.
Magnetic declination is caused by the complex shape of the Earth's magnetic field which defines to the use of a compass with its needle pointing north for navigation.
Thus, the difference between the positions of these two poles when viewed at different locations is defined as the magnetic declination which allows these angles for navigators to determine their true geographic position.

What is the frequency of light with a wavelength of 725 nm?
The frequency of light with a wavelength of 725 nanometers is approximately 4.14 × 10^14 Hz, which is calculated using the formula for the relationship between the speed of light, wavelength, and frequency.
Explanation:The frequency of light can be calculated using the equation c = fλ, where 'c' is the speed of light, 'f' is the frequency, and 'λ' is the wavelength. The speed of light (c) is approximately 3.00 × 108 m/s. So, if the light has a wavelength of 725 nm (or 725 × 10-9 m, to convert nanometers to meters), the equation can be rearranged to solve for frequency (f): f = c/λ.
Substituting the given values, then we get: f = (3.00 × 108 m/s) / (725 × 10-9 m) = 4.14 × 1014 Hz. Therefore, the frequency of light with a wavelength of 725 nm is approximately 4.14 × 1014 Hz.

How to find acceleration with mass coefficient of friction and applied force
Final answer:
To find acceleration with mass, coefficient of friction, and applied force, we can use Newton's second law and the formula for frictional force. The applied force can be calculated by subtracting the force of friction from the net force.
Explanation:
To find acceleration with mass, coefficient of friction, and applied force, we can start with Newton's second law. Newton's second law states that the net force on an object is equal to the mass of the object multiplied by its acceleration: F_net = m * a. In the case of friction, we can use the formula for frictional force: F_friction = µ * N, where µ is the coefficient of friction and N is the normal force.
The normal force can be calculated as the product of mass and acceleration due to gravity: N = m * g. The applied force can be calculated by subtracting the force of friction from the net force: F_net - F_friction = F_applied.

two sets of 3 consecutive integers have a property that the product of the larger two is one less than seven times the smallest set up and solve an equation that can be used to find both sets of intigers
Final answer:
To find the two sets of consecutive integers that satisfy the given property, we can set up and solve an equation. The equation is (x+1)(x+2) = 7x - 1. Solving this equation, we find two possible values for x: 1 and 3. Substituting these values, we find the two sets: {1, 2, 3} and {3, 4, 5}.
Explanation:
To find the two sets of consecutive integers, let's assign variables to the smallest integer in each set. Let's say the first set starts with x, so the consecutive integers in that set would be x, x+1, and x+2. Similarly, let's say the second set starts with y, so the consecutive integers in that set would be y, y+1, and y+2.
According to the given property, the product of the larger two integers (in this case, (x+1)(x+2)) is one less than seven times the smallest integer (in this case, 7x-1).
We can now form an equation: (x+1)(x+2) = 7x - 1.
To solve this equation, we can expand the left side and then simplify:
x^2 + 3x + 2 = 7x - 1
x^2 - 4x + 3 = 0
Now, we can factor the quadratic equation:
(x - 1)(x - 3) = 0
So the possible values for x are 1 and 3. Substituting these values back into the original equations, we can find the two sets of consecutive integers:
For x = 1, the integers are 1, 2, 3. And for x = 3, the integers are 3, 4, 5.
Therefore, the two sets of consecutive integers that satisfy the given property are {1, 2, 3} and {3, 4, 5}.

Explanation:
The magnetic spectrum consists invisible and visible part of the spectrum. The invisible part consists of radio waves. These are waves used for radios, tvs, and cellphone communications. They satisfy all the properties of transverse waves.
The visible part comes from light. This is the part that is visible to the naked eye. Examples are ultraviolet rays, the sun, neon lights etc. To determine how hot something is, the visible portion is used. The brighter the object, the hotter it is. Thus, the brightness of the stars can be determined by the color of the light emitted. The visible rays satisfy all the properties of transverse waves. However, light is considered a dual nature - it has wave and electron-like properties.
