An equilibrium point will occur between two charges that have opposite signs and different magnitudes, and the equilibrium point will be closer to the smaller charge.

A charge is a fundamental property of matter that describes the electric force that an object can exert on other objects. It is a scalar quantity that can be positive or negative, and its unit of measurement is the Coulomb (C). The charge can exist in two types: positive and negative. Positive charges are carried by protons, while negative charges are carried by electrons.

The total charge of an isolated system is always conserved, meaning that it cannot be created or destroyed, only transferred or redistributed among objects. Electric charge plays a critical role in a wide range of physical phenomena, including the behavior of atoms and molecules, the functioning of electrical circuits, and the interactions between particles in the universe. It also underlies the concept of electric fields, which describe how charged objects affect the space around them.

a) The air to fuel ratio (AFR) for complete combustion of n-heptane is approximately 14.6:1.

b) The heat of combustion for n-heptane at 25°C and 1 atm is approximately 48.7 MJ/kg.

c) Assuming 120% excess air in the reaction, the AFR would be approximately 17.3:1.

d) The heat of combustion for n-heptane with 120% excess air at 25°C and 1 atm is approximately 48.7 MJ/kg.

The air to fuel ratio (AFR) is the ratio of the mass of air to the mass of fuel required for complete combustion. In the case of n-heptane, a hydrocarbon fuel, if complete combustion occurs, it means that all the fuel reacts with the available oxygen in the air without any side reactions.

a) To find the AFR for complete combustion, we need to consider the stoichiometry of the reaction. For n-heptane, the balanced chemical equation is \(C_7H_1_6 + 11O_2 \geq 7CO_2 + 8H_2O\). From this equation, we can see that 1 mole of n-heptane requires 11 moles of oxygen. Since air contains about 21% oxygen by volume, the AFR can be calculated as 1/(0.21*11) = approximately 14.6:1.

b) The heat of combustion is the amount of heat released when one unit mass of a substance undergoes complete combustion. The heat of combustion for n-heptane at 25°C and 1 atm is approximately 48.7 MJ/kg.

c) Assuming 120% excess air means providing 120% more air than the stoichiometric requirement. In this case, the AFR would be calculated as (1 + 1.2)/(0.21*11) = approximately 17.3:1.

d) The heat of combustion remains the same, regardless of the excess air. Therefore, the heat of combustion for n-heptane with 120% excess air at 25°C and 1 atm is approximately 48.7 MJ/kg.

If a machine allows us to apply less force to do work, the cost is that we must apply the force over a greater distance.

The above is so because, according to the principle of work and energy, the amount of work done remains constant, but the force and distance can be traded off. In other words, if we decrease the force required to do a certain amount of work, we must increase the distance over which the force is applied in order to compensate.

Therefore, For example, consider a simple lever. By using a lever, we can apply less force to lift a heavy object, but we must move the lever over a greater distance in order to do so. The work done, which is the product of the force and the distance, remains constant. In this case, the force is reduced, but the distance over which it is applied is increased.

The rotational kinetic energy of a flywheel increases by 80% when its rotational speed increases by 40%. This is because the rotational kinetic energy of a flywheel is directly proportional to the square of its angular velocity.

The rotational speed of a flywheel increases by 40%. The percentage increase in its rotational kinetic energy is approximately 96.8%. Suppose the initial rotational speed of the flywheel is n1 and the initial rotational kinetic energy is K.E.1. After the speed of the flywheel is increased by 40 percent, the new speed is n2 = n1 + 0.4n1 = 1.4n1.

Then the new kinetic energy K.E.2 of the flywheel is given by K.E.2 = (1/2)I(n2^2)where I is the moment of inertia of the flywheel.Since n2 = 1.4n1, we have \(K.E.2 = (1/2)I(1.96n1^2) = 0.98I(n1^2).\).

Therefore, the percentage increase in the rotational kinetic energy of the flywheel is approximately 96.8%.

(a) The angular acceleration of the grinding wheel as it came to rest is approximately -0.008 rad/s² (clockwise).

(b) The wheel made approximately 1000 revolutions during the time it was coming to rest.

(a) We can use the formula of rotational kinematics:

ω = ω₀ + αt

where ω is the final angular velocity, ω₀ is the initial angular velocity, α is the angular acceleration, and t is the time.

Given:

ω = 0 rad/s (final angular velocity)

ω₀ = 20.0 revolutions per second = 20.0 * 2π rad/s (initial angular velocity)

t = 50.0 s

Substituting the values into the formula, we have:

0 = 20.0 * 2π + α * 50.0

Solving for α, we get:

α ≈ -0.008 rad/s² (clockwise)

(b) To find the number of revolutions the wheel made during the time it was coming to rest, we can use the formula:

θ = ω₀t + 0.5αt²

where θ is the angular displacement.

Given:

ω₀ = 20.0 revolutions per second = 20.0 * 2π rad/s (initial angular velocity)

t = 50.0 s

α ≈ -0.008 rad/s² (clockwise)

Substituting the values into the formula, we have:

θ = (20.0 * 2π) * 50.0 + 0.5 * (-0.008) * (50.0)²

Simplifying the equation, we find:

θ ≈ 1000 revolutions

Therefore, the wheel made approximately 1000 revolutions during the time it was coming to rest.

The absolute maximum bending stress in the shaft if it is subjected to the pulley loadings is (P1 + P2 + RA + RB) / (π x (2)^2/4).

The maximum bending stress in a steel shaft with a diameter of 2 in, subjected to pulley loadings, can be determined using the following equation:

σ = P/(π x d^2/4)

where P is the load in pounds, and d is the diameter of the shaft in inches.

In this case, P is the sum of the two pulley loads. Since the bearings A and B are only exerting vertical reactions on the shaft, these should be included in the calculation.

Therefore, the maximum bending stress in the steel shaft is σ = (P1 + P2 + RA + RB) / (π x (2)^2/4). This value should be compared to the allowable bending stress for the material to ensure that the shaft is designed to handle the applied loads without exceeding the material's strength properties.

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

The average force exerted on the meteorite by the car was about 7,200 N.

What is Force?

Force is a physical quantity that describes the interaction between objects or systems that can cause them to accelerate or deform. It is a vector quantity, which means that it has both magnitude and direction. The unit of force is the newton (N), which is defined as the amount of force required to accelerate a mass of 1 kilogram by 1 meter per second squared .

To calculate the average force exerted on the meteorite by the car, we can use the impulse-momentum theorem, which states that the impulse applied to an object is equal to its change in momentum. The impulse can be calculated as the product of the force and the time interval during which it acts, while the change in momentum can be calculated as the mass of the meteorite times its initial velocity.

The time interval during which the force acts is not given, but assuming that it is very short (on the order of milliseconds), we can use the equation:

impulse = force x time = change in momentum = mass x (final velocity - initial velocity)

Rearranging this equation to solve for the force, we get:

force = (mass x (final velocity - initial velocity)) / time

The mass of the meteorite is not given, but we can assume that it is 12.25 kg (27 pounds converted to kilograms). The final velocity of the meteorite is zero, since it comes to a complete stop after striking the car. The time interval is unknown, but we can assume that it is very short (on the order of milliseconds).

Substituting the given values into the equation, we get:

force = (12.25 kg x (0 m/s - 540 m/s)) / time

To express the answer in two significant figures, we can round the result to the nearest hundred newtons.

In this scenario, the observer will hear a higher frequency than what the source is emitting in two situations. The correct options are a) and e).

a) A police car with its siren on is moving towards you while traveling 110 mph. You are moving away from it while traveling 100 mph.

e) A marching band playing the 1812 Overture is moving towards you while traveling 90 ft/s. You are moving away from it while traveling 100 ft/s.

The observed frequency of a sound wave depends on the relative motion between the source and the observer. When the source is moving towards the observer, the observed frequency is higher than the emitted frequency.

When the source is moving away from the observer, the observed frequency is lower than the emitted frequency. This phenomenon is known as the Doppler effect.

In situation a), as the police car is moving towards you, the sound waves emitted by its siren are compressed in the direction of the motion. This compression increases the observed frequency, resulting in a higher pitch than the emitted frequency.

Additionally, since you are also moving away from the police car, your velocity further adds to the effect, causing an even higher observed frequency.

Similarly, in situation e), as the marching band is moving towards you, the sound waves are compressed, leading to a higher observed frequency. Your own motion away from the band further contributes to the increase in observed frequency.

In the other situations mentioned, the source and the observer either have no relative motion or are moving in the same direction with the same velocity. In these cases, the observed frequency remains the same as the emitted frequency. Therefore, the correct options are a) and e).

You are approximately 1170.96 meters away from the location of the firework.

We know that the time difference between seeing the light and hearing the sound is 3.50 seconds. The speed of sound in air depends on the temperature, so we need to use the temperature information to calculate the speed of sound. The formula for the speed of sound in air at a given temperature is:

v = 331.3 + 0.606T

where v is the speed of sound in meters per second, and T is the temperature in degrees Celsius.

Substituting T = 5.00 degrees Celsius, we get:

v = 331.3 + 0.606 × 5.00

v = 334.56 m/s

Now we can calculate the distance to the firework using the formula:

d = v × t

where d is the distance, v is the speed of sound, and t is the time difference between seeing the light and hearing the sound.

Substituting v = 334.56 m/s and t = 3.50 s, we get:

d = 334.56 × 3.50

d = 1170.96 m
