The phenomenon in hearing that is analogous to spatial frequency channels in vision is critical bands. Hence, the correct option is A: Critical bands.

Critical bands are regions of the audible frequency range in which a complex sound is divided into individual, discrete frequency bands by the human auditory system.

For instance, when different frequencies in a complex sound, such as a musical instrument or a human voice, are picked up by the ear, they are sent to the brain via various channels that respond to specific frequencies.

These channels are referred to as critical bands. The frequency range of these bands varies depending on the loudness of the sound.

Fossil fuels e.g., coal, oil and gas are non renewable energy sources because they take years to form.

When a 35.0%-efficient Carnot heat engine is run in reverse to form a refrigerator, the refrigerator's coefficient of performance would be 2.857.

The coefficient of performance (COP) of a refrigerator is a measure of its efficiency in removing heat. It is defined as the ratio of the heat removed from the refrigerated space to the work input.
In this case, we are given that the Carnot heat engine is 35.0% efficient. The efficiency of a heat engine is defined as the ratio of the work output to the heat input.

Since the refrigerator is the reverse of the Carnot heat engine, the COP of the refrigerator can be determined by taking the reciprocal of the efficiency of the heat engine.

To calculate the COP of the refrigerator, we can use the formula:

COP_refrigerator = 1 / efficiency_heat_engine

Given that the efficiency of the Carnot heat engine is 35.0%, we can substitute this value into the formula:

COP_refrigerator = 1 / 0.35

Simplifying the expression:

COP_refrigerator = 2.857

Therefore, the coefficient of performance of the refrigerator is approximately 2.857.
In conclusion, when a 35.0%-efficient Carnot heat engine is run in reverse to form a refrigerator, the refrigerator's coefficient of performance would be 2.857.

In this case, the Coefficient of Performance (COP) for the refrigerator after reversing a 35.0% efficient Carnot engine is 1.54, illustrating the high efficiency of the Carnot refrigerator when used as model for heat engine devices.

In the context of thermodynamics, when a Carnot engine is reversed, it operates as a refrigerator. As given, the Carnot engine has an efficiency of 35.0%, which means the Coefficient of Performance (COP) for the refrigerator mode would be given by COP = 1 / (1 - Efficiency). Here Efficiency is given as 0.35. So, the COP = 1 / (1 - 0.35) = 1.54.

Essentially, a Carnot refrigerator (like a Carnot heat engine) is based on the Carnot cycle, which is an ideal thermodynamic cycle used as an idealized model for heat engines and refrigerators. Its high coefficient of performance makes it an optimal model for these devices.

If the moon were at its gibbous phase as seen from Earth, the phase of the Earth as seen from the moon would be a nearly full Earth.

This is because the phase of the Earth as seen from the moon is opposite to the phase of the moon as seen from Earth. So, if the moon is at its gibbous phase, it means that the sun is illuminating more than half of the moon's surface, and the remaining part of the moon is in shadow. From the moon's perspective, the Earth would appear as a mostly illuminated disk with just a small part in shadow, making it almost a full Earth.

The maximum acceleration of the simple harmonic oscillator is 9.8 m/sec^2.

The maximum acceleration of a simple harmonic oscillator can be calculated using the formula

a max = 4π^2A/T^2

where A is the amplitude and T is the period.

Plugging in the given values of A = 0.65 m and T = 3.6 sec, we get:

a max = 4π^2(0.65 m)/(3.6 sec)^2

Simplifying the expression, we get:

a max = 4π^2(0.65 m)/12.96 sec^2

a max = 4π^2(0.05 m/sec^2)

a max = 9.8 m/sec^2

Therefore, this means that the oscillating object experiences a maximum acceleration of 9.8 m/sec^2 at the extreme points of its motion (i.e. when it is at the furthest point from equilibrium).

* using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2

V2= 1.54 liters which proves when temperature decreases , volume decreases as well.

Explanation:

The volume increases as the temperature increases, and volume decreases as the temperature decreases.

using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2

Change Celsius to kelvin by adding 273.

2 liters/ 315 K = V2/243 K

Cross multiply and then divide by 315 to find V2

2 liters x 243 K / 315 K = V2

The Kelvin cancels itself out.

486 liters /315=V2

V2= 1.54 liters.

This proves that when the temperature decreases , so does the volume.

Of the proposed alternatives to human-induced climate change discussed in class, the one that operates over the same time interval as the recent rapid rise in global temperature is the increase in greenhouse gas emissions, primarily carbon dioxide (CO2) from burning fossil fuels.

The rapid rise in global temperature is mainly due to human activities, such as burning fossil fuels for energy, deforestation, and industrial processes.

These activities release large amounts of CO2 and other greenhouse gases into the atmosphere, trapping heat and causing the Earth's temperature to rise.

This process has been accelerated in recent decades, aligning with the increase in industrialization, urbanization, and global energy consumption.

Consequently, reducing greenhouse gas emissions is a critical strategy to mitigate the effects of human-induced climate change and slow down the warming trend.

The speed is constant and the direction of motion changes.

Thus, the car maintains a constant speed and it does not maintain a constant velocity - the instantaneous speed varies as it goes around the corner due to the change in direction of motion.

When a car rounds a corner at a steady speed, it changes its direction of motion, and therefore, its velocity changes as well. Velocity is a vector quantity that takes into account both the speed and direction of an object's motion. Since the direction changes, the velocity changes as well. However, if the car maintains the same speed throughout the turn, then the speed remains constant. Speed is a scalar quantity that only takes into account the magnitude of an object's motion, and it is measured as the distance traveled per unit of time.

Answer:

Energy.

Explanation:

Émilie du Châtelet is known for her work in physics and mathematics in the 1700s, during a time when women were not typically involved in these fields. One of her most significant contributions was her translation and commentary on Isaac Newton's "Principia Mathematica," which helped to spread Newton's ideas throughout Europe.

In her own research, Émilie du Châtelet made significant contributions to the understanding of energy and conservation laws. Specifically, she formulated and tested a conservation law for what she called "living force," which we now understand as kinetic energy. This quantity depends on an object's mass and the square of its speed, and is conserved in a closed system, just like momentum. Her work laid the foundation for the modern concept of energy conservation, which is a fundamental principle in physics.

The modern concept of energy conservation and helped establish the importance of mathematics in physics.

Émilie du Châtelet formulated and tested the conservation law for kinetic energy, which is the quantity that depends on an object's mass and the square of its speed. Kinetic energy is the energy an object possesses due to its motion, and it is defined as one-half the product of an object's mass and the square of its velocity, or KE = 1/2mv².

Before Châtelet, the concept of energy was not well-defined, and many scientists believed that the total amount of motion in a closed system was conserved. Châtelet, however, recognized that kinetic energy is distinct from momentum and that energy can be transformed from one form to another, but it cannot be created or destroyed.

To test her theory, Châtelet performed experiments in which she dropped balls from various heights and measured their velocities upon impact. She found that the total energy of the system (the sum of the kinetic energy of the ball and the potential energy due to its height) was conserved throughout the process, even though the ball's momentum changed due to the force of gravity.

Châtelet's work laid the foundation for the modern concept of energy conservation and helped establish the importance of mathematics in physics.

Answer:

huh

Explanation:

Sometimes no. such as in other types of waves like electromagnetic waves, the medium does not physically move with the wave.

The medium in which a wave travels can move with the wave under certain circumstances, but it is not always the case. The movement of the medium depends on the type of wave and the nature of the medium itself. In mechanical waves, such as sound waves or water waves, the medium particles do indeed move as the wave propagates through them. For example, in a water wave, the water molecules move in a circular or elliptical motion as the wave passes through the water. Electromagnetic waves, including light waves, can travel through vacuum, which has no physical medium. In this case, the wave consists of oscillating electric and magnetic fields that propagate through space without the need for a medium to physically move. Therefore, whether the medium moves with the wave or not depends on the specific characteristics of the wave and the medium it is traveling through.

Answer:

 U = 25 J

Explanation:

The energy in a set of charges is given by

          U = \(k \sum \frac{q_i}{r_i}\)

in this case we have three charges of equal magnitude

          q = q₁ = q₂ = q₃

with the configuration of an equilateral triangle all distances are worth

          d = a

          U = k ( \(\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3}\) )

we substitute

           15 = k q² (3 / a)

            k q² /a = 5

For the second configuration a load is moved to the measured point of the other two

          d₁₃ = a

The distance to charge 2 that is at the midpoint of the other two is

          d₁₂ = d₂₃ = a / 2

           U = k (\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3})

            U = k q² (  \(\frac{2}{a} + \frac{1}{a} + \frac{2}{a}\) )

            U = (kq² /a) 5

substituting

            U = 5 5

            U = 25 J
