The resistance of the resistor in this circuit is 82.31 Ohms

We would first have to solve for the angular frequency

ω = 2π* f

f = 180 hz

= 2* 3.14 * 180

= 1130.4

Next we would have to solve for the  Inductive reactance XL = ω* L

= 1130.4 * 0.027

= 30.52

The current is

3.2 v / 30.52

= 0.1048

Impedance Z = V/ I

9.2 v / 0.1048

= 87.79

To get the resistance we would have to use

Z² = (R² + XL²)

87.79² = R² + 30.52²

R²  = 87.79² - 30.52²

= 7707.08 - 931.47

= 6775.6

R = √6775.6

= 82.31 ohms

Answer:Because if the shape gets changed it will move faster without to much weight

Explanation:

Answer: If Maxwell's wheel were to rotate twice as fast, its kinetic energy would increase by a factor of four. This is because the kinetic energy is proportional to the square of the angular velocity.

Explanation:

I'm assuming that you are referring to a specific laboratory experiment or problem. However, you haven't provided any details about the experiment or the given information. Please provide me with the necessary information to answer your questions.

However, I can provide you with some general information that may help you solve your problem.

To find the angular velocity of the wheel when it is fully unwound, you can use the conservation of energy principle. The initial energy of the system is equal to the final energy of the system. The initial energy is the potential energy stored in the spring, which is given by ½kx², where k is the spring constant and x is the displacement of the spring. The final energy is the rotational kinetic energy of the wheel, which is given by ½ Iω², where I am the moment of inertia of the wheel and ω is the angular velocity. Setting these two energies equal, you can solve for ω.

To compute the downward acceleration of a falling wheel of the same shape and size but made of a different material which is three times as heavy, you need to use the equation for the gravitational force, which is given by F = mg, where m is the mass of the object and g is the acceleration due to gravity. Since the mass of the wheel is three times as heavy, the gravitational force acting on it will also be three times as heavy. Therefore, the downward acceleration will be the same as that of a wheel of normal weight.

If the radius of the axle of Maxwell's wheel is reduced to ½ the measured value, whereas the disk remains the same, the moment of inertia of the wheel will decrease. This is because the moment of inertia is proportional to the square of the radius. Therefore, the downward acceleration will be bigger. The exact value of the acceleration will depend on the new moment of inertia of the wheel.

To find a value a that is accurate to within a few percent, you need to provide me with the necessary information about the experiment or the problem.

The ratio of the moments of inertia of a disk and a hoop of the same radius and mass is ½. This can be derived using the formula for the moment of inertia of a disk (½mr²) and a hoop (mr²) and dividing the moment of inertia of the hoop by the moment of inertia of the disk.

If Maxwell's wheel were to rotate twice as fast, its kinetic energy would increase by a factor of four. This is because the kinetic energy is proportional to the square of the angular velocity.

Answer:

\(\boxed{0}\)

Explanation:

Momentum is the measure of mass in motion.

\(\sf momentum = mass \times velocity\)

An object at rest has a velocity of 0.

\(p=mv\)

\(p = 25 \times 0\)

\(p=0\)

The momentum of an object at rest is always 0.

When there is a steady current in the circuit, the amount of charge passing a point per unit of time is the same everywhere in the circuit.

According to Ohm's law, the current flowing through a conductor is directly proportional to the potential difference (voltage) applied across it and inversely proportional to its resistance. In a series circuit, the current is constant throughout because the resistance is the same everywhere. Therefore, the amount of charge passing a point per unit of time is also constant and it is not affected by the value of the resistance..

The mirror reflects the light while the lens allows the light to pass through it. The lens and mirror are positioned parallel and opposite each other.

The basic difference between the lens and mirror is that mirror reflects the light while the lens allows the light to pass through it. Both are optical instruments but their laws are different.

The lens and mirror are positioned parallel and opposite each other. From the above conditions, it is observed that first, the light gets passed through the lens.

After it passes through the light got reflected. As the light reflected the mirror it again passes through the lens and converts the distributed or parallel lights into a single beam of light.

The single beam of light is known as the spotlight.

Such types of design for a spotlight use a lens and a mirror, combined with a gas-discharge lamp, to project a powerful parallel beam of light.

the wavelengths in the hydrogen spectrum of the first four members of the series where m=1, the first four members have the wavelength of \(1.464 * 10^7 m,\) \(1.231 * 10^7 m,\) \(1.164 * 10^7 m,\) and \(1.097 * 10^7 m.\)

The wavelengths of the spectral lines in the Lyman series of the hydrogen spectrum can be calculated using the Rydberg formula:

1/λ = \(R * (1/n1^2 - 1/n2^2)\)

Where λ is the wavelength of the spectral line, R is the Rydberg constant (approximately \(1.097 * 10^7 m^-^1)\), and n1 and n2 are positive integers representing the energy levels of the electron in the hydrogen atom.

For the Lyman series, we have m = 1, which means the electron transitions from higher energy levels (n2) to the first energy level (n1 = 1).

Let's calculate the wavelengths for the first four members of the Lyman series:

For n2 = 2:

1/λ = \(R * (1/1^2 - 1/2^2)\)

1/λ = \(R * (1 - 1/4)\)

1/λ = \(R * (3/4)\)

λ = \(4/3R\)

Substituting the value of the Rydberg constant:

λ = \((4/3) * (1.097 × 10^7 m^-^1)\)

λ ≈ \(1.464 * 10^7 m\)

For n2 = 3:

1/λ = \(R * (1/1^2 - 1/3^2)\)

1/λ = \(R * (1 - 1/9)\)

1/λ = \(R * (8/9)\)

λ = \(9/8R\)

Substituting the value of the Rydberg constant:

λ = \((9/8) * (1.097 * 10^7 m^-1)\)

λ ≈ \(1.231 * 10^7 m\)

For n2 = 4:

1/λ = \(R * (1/1^2 - 1/4^2)\)

1/λ = \(R * (1 - 1/16)\)

1/λ = \(R * (15/16)\)

λ = \(16/15R\)

Substituting the value of the Rydberg constant:

λ = \((16/15) * (1.097 * 10^7 m^-^1)\)

λ ≈ \(1.164 * 10^7 m\)

For n2 = 5:

1/λ = \(R * (1/1^2 - 1/5^2)\)

1/λ = \(R * (1 - 1/25)\)

1/λ = \(R * (24/25)\)

λ = \(25/24R\)

Substituting the value of the Rydberg constant:

λ = \((25/24) * (1.097 * 10^7 m^-^1)\)

λ ≈ \(1.097 * 10^7 m\)

Therefore, the wavelengths of the first four members of the Lyman series are approximately:

\(1.464 * 10^7 m,\)

\(1.231 * 10^7 m,\)

\(1.164 * 10^7 m,\)

and \(1.097 * 10^7 m.\)

During the ice age, the total amount of energy in the Earth system decreased due to changes in orbital parameters (Milankovitch cycles), redistributing solar energy, while atmospheric CO2 levels decreased as a feedback mechanism, amplifying the cooling effect.

During the ice age, the total amount of energy in the Earth system decreased. This change occurred primarily due to changes in Earth's orbital parameters known as Milankovitch cycles. These cycles affect the distribution and intensity of solar radiation reaching the Earth's surface.

Milankovitch cycles involve variations in the Earth's eccentricity, axial tilt, and precession. These variations lead to changes in the amount and distribution of solar energy received by different parts of the Earth over long periods. However, it's important to note that the total amount of energy from the Sun did not change during the ice age.

The decrease in the total amount of energy in the Earth system resulted from the redistribution of solar energy due to Milankovitch cycles. These variations caused changes in the Earth's climate system, including the redistribution of heat through changes in the intensity and seasonality of sunlight.

The ice age was primarily triggered by a combination of Milankovitch cycles and the resulting changes in the Earth's climate. As solar radiation distribution shifted, it influenced temperature gradients and altered atmospheric circulation patterns. This led to changes in precipitation patterns and the formation of large ice sheets in regions where snowfall exceeded melting.

The decrease in atmospheric carbon dioxide (CO2) levels observed in the ice record during the ice age was a feedback mechanism rather than a direct cause. As the climate cooled, the capacity of cold water to dissolve and retain CO2 increased, leading to its absorption by the oceans. This caused a decrease in atmospheric CO2 levels, further amplifying the cooling effect.

In summary, the ice age was primarily caused by variations in Earth's orbital parameters (Milankovitch cycles), resulting in a redistribution of solar energy and changes in climate. The decrease in the total amount of energy in the Earth system was a consequence of these changes, while the decrease in atmospheric CO2 levels acted as a feedback mechanism, reinforcing the cooling effect.

T = 2π √(l/g) is equation for the period of oscillation of a simple pendulum.

Define period of oscillation.

The length of time it takes for a basic pendulum to swing back and forth from one position to the next is its period of oscillation. We typically use the extreme position as a reference since the pendulum is more relaxed there, making computations simpler.

The length (l) of the pendulum—the distance from the pivot point to the center of the attached mass—determines the oscillation period. The gravity of the system (g) varies from planet to planet and at different heights inside a planet since gravity changes with height. The period of oscillation of the pendulum is unaffected by the mass of the pendulum.

Solution:

The EMF of a cell represents its maximum potential difference, while the potential difference across the cell when passing a current through an external resistance is reduced due to the internal resistance of the cell.

The electromotive force (EMF) of a cell refers to the maximum potential difference that the cell can provide when it is not connected to any external circuit. It is essentially the voltage produced by the chemical reactions occurring within the cell. On the other hand, the potential difference across the cell when it is passing a current through an external resistance is often lower than the EMF.

This difference in values can be attributed to the internal resistance of the cell. When a current is drawn from the cell, it encounters resistance within the cell itself due to factors such as the resistance of the electrolyte and the internal structure of the cell. This internal resistance causes a voltage drop within the cell, reducing the potential difference across the external circuit.

According to Ohm's Law (V = I * R), when current flows through a resistance (R), a voltage drop (V) occurs. In this case, the internal resistance of the cell causes a voltage drop within the cell itself. Hence, the potential difference across the external resistance is slightly lower than the EMF of the cell.
