The force of the racket on the ball compared to the force of the ball on the racket is the same. So, option (3) is correct.

The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

Every time one object applies force to another, the other object applies an equal and opposing force to the first.

According to Newton's third law, there is an equal and opposite reaction to every force (action) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces. So, the force of the racket on the ball compared to the force of the ball on the racket is the same.

Charged particles are fundamental to the behavior of electric currents, electric circuits, and resistance. An electric current is the flow of charged particles, typically electrons, through a conductor.

The flow of charged particles generates an electric field that induces a potential difference, or voltage, across the conductor.Electric circuits are constructed by connecting conductors and electrical components, such as resistors, capacitors, and inductors, in a specific configuration. The arrangement of the components determines how the current flows through the circuit.

The flow of current through the circuit depends on the resistance offered by the components in the circuit and the potential difference across the circuit.Resistance is the property of a conductor that opposes the flow of current. The resistance of a conductor is proportional to the number of charged particles in the conductor, the length of the conductor, and the cross-sectional area of the conductor. The resistance can also be affected by the temperature of the conductor and its material properties.

In summary, charged particles are responsible for generating electric currents that flow through electrical circuits. The behavior of the currents is determined by the arrangement of the components in the circuit and the resistance offered by the conductors and components. Resistance is a fundamental property of a conductor that opposes the flow of charged particles and can be affected by various factors.

The phenomenon observed is doppler effect and the speed of the ambulance would be 374 m/s.

The Doppler effect equation for sound waves is given by:

f' = f(v ± v₀) / (v ± vᵢ)

Where f is the frequency of the emitted sound wave, f' is the observed frequency, v is the speed of sound in air, v₀ is the velocity of the observer relative to the air, and vᵢ is the velocity of the source relative to the air.

In this case, the person standing next to the road is the observer, and the ambulance is the source. The observed frequency f' is 0.9f, and the speed of sound in air v is 340 m/s.

Substituting these values into the equation, we get:

0.9f = f(v + v₀) / (v - vᵢ)

Simplifying and rearranging, we get:

v₀ = (0.1v + vᵢ)

The ambulance is moving away from the observer, so v₀ is negative. Substituting the known values, we get:

v = 340 m/s

v₀ = -0.1v

v - v₀ = v + 0.1v = 1.1v

Therefore, the velocity of the ambulance is:

vᵢ = v(1 - v₀/v) = v(1 + 0.1) = 1.1v

vᵢ = 1.1(340 m/s) = 374 m/s

So the speed of the ambulance is 374 m/s.

The magnitude of the electric force, F, on the test charge is given by:

F = k * q0 * (p / (r^2))

The magnitude of the electric force on a test charge q0 placed at a distance r away from a dipole can be calculated using Coulomb's law. Coulomb's law states that the force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.

For a dipole, the electric force can be calculated by considering the force between the test charge and each of the charges in the dipole and then adding the forces vectorially.

A dipole is a two-point electrical charge system, where one point has a positive charge and the other has an equal and opposite negative charge.

Dipoles are fundamental to many electrical and chemical processes, and they play a crucial role in molecular bonding and interactions. Dipoles can also be created artificially, such as in an electric dipole or a magnetic dipole.

The magnitude of the electric force, F, on the test charge is given by:

F = k * q0 * (p / (r^2))

where k is Coulomb's constant (approximately 8.99 x 10^9 N(m/C)^2), p is the dipole moment, and r is the distance between the test charge and the dipole. The dipole moment can be calculated from the magnitude of the charges in the dipole and the separation distance between them.

The repulsion force between the two Arkon nuclei when the distance between them is 1x10⁻³μm is approximately 7.4x10⁻¹⁴N. The correct option is d. 7.4x10⁻¹⁴N.

The formula for repulsion force between two Arkon nuclei when the distance between them is given by Coulomb's law. Coulomb's law states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, the law can be expressed as F=kq1q2/r²,

Where F is the force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb's constant.The electric charge of one electron is 1.6x10⁻¹⁹C.

Therefore, the charge of the Arkon nucleus with 18 protons = 18(1.6x10⁻¹⁹) C = 2.88x10⁻₈⁸ CThe force between the two Arkon nuclei can be calculated using the formula above.

F=kq1q2/r²

Substituting the values we have;F = (9x10⁹)(2.88x10⁻¹⁸ C)2/(1x10⁻³ m)2F ≈ 7.4x10⁻¹⁴ N. Therefore, the repulsion force between the two Arkon nuclei when the distance between them is 1x10-3μm is approximately 7.4x10⁻¹⁴N. The correct option is d. 7.4x10⁻¹⁴N.

Answer: 6,277,647m

Explanation:

Radius of Earth = 6400km

To calculate the gravitational acceleration of a planet, we use the following formula:

g = mG/r^2

Gravitational acceleration is equal to the mass of the planet multiplied by the gravitational constant all divided by the radius of the planet squared.

We already know what the gravitational acceleration will be, 2.45m/s^2.

So, 2.45m/s^2 = mG/r^2

the mass of the earth is equal to 5.9*10^24.

And the gravitational constant is equal to 6.67408 * 10^-11.

We don't know the radius though.

2.45m/s^2 = 5.9*10^24 * 6.67408 * 10^-11 divided by r^2

2.45m/s^2 = 3.93 * 10^14 divide by r^2

Now, we can cross-multiply.

2.45m/s^2 * r^2 = 3.93 * 10^14

divide r^2 from both sides.

r^2 = 3.93 * 10^14 divided by 2.45m/s^2

r^2 = 1.6*10^14.

Now, take the square root of both sides.

r = 12,677,647 meters from the center of the Earth.

To calculate the height from the surface of the Earth, we need to subtract r by the Earth's radius.

That will be 12,677,647-6.400.000m = 6,277,647m from the surface of Earth.

According to the Bohr model, the energy levels of a hydrogen atom are given by the equation E = -13.6 \(eV/n^{2}\), where n is the principal quantum number.

The 6th excited state refers to the state where the electron is in the 7th energy level, since the ground state is considered to be n = 1. Plugging this value into the equation, we get E = -13.6 \(eV/7^{2}\) = -0.216 eV.

This energy level is relatively high, meaning the electron is far from the nucleus and is therefore loosely bound.

Hydrogen atoms in this excited state are typically unstable and can undergo transitions to lower energy levels by emitting photons of specific wavelengths.
