Answer:

The correct option is D. 4.3×10¹⁴ Hz

Explanation:

It is because the frequency and the wavelength are inversely proportional to each other.

So, c=f × lambda

And, frequency = velocity/wavelength

The frequency of the laser beam is D. 4.3×10¹⁴ Hz

One hertz (Hz) equals one cycle per second. A complete AC or voltage wave is called a cycle. The first half of the cycle is alternating. Period is the time it takes a waveform to complete a complete cycle. Frequency is essentially how often something repeats.

The rate at which the current changes direction in one second is called the frequency. Expressed in hertz (Hz), the international unit of measurement. One hertz equals one cycle per second.

The horizontal speed at which the water leaves the hole is[tex]4.09 ms^-1.[/tex]

Speed is the rate of change of the position of an object in a given direction. It is expressed as the distance traveled per unit of time, typically measured in meters per second (m/s). It is also commonly represented by the symbol ‘v’. Speed is a scalar quantity, meaning it has only magnitude, not direction.

The kinetic energy per unit volume at the point of the hole is equal to the density of the water multiplied by one-half the square of the velocity of the water leaving the hole.

Since these two values are constant across a horizontal streamline, we can set up the following equation:

[tex]ρgh = ρ(v^2/2)[/tex]

Solving for v, we get:

[tex]v = √(2gh)[/tex]

Plugging in the values for the height of the water above the hole (h = 0.4 m) and the acceleration due to gravity[tex](g = 9.81 ms^-2)[/tex], we get:

[tex]v = √(2*9.81*0.4) = 4.09 ms^-1[/tex]

The coefficient of kinetic friction for the skier if the magnitude of frictional force is 25N will be 0.04638.

Kinetic friction can be defined as a force which acts between the moving surfaces. A object moving on the surface experiences a force in the opposite direction of the movement. The magnitude of the force will also depend on the coefficient of kinetic friction between the two objects.

F = μk Fn

where, F is the frictional force,

μk is the coefficient of kinetic friction,

Fn is the normal force

Fn = mass × acceleration due to gravity

Fn = 55 × 9.8

Fn = 539N

F = μk Fn

F = 25N,

25 = μk × 539

μk = 25/ 539

μk = 0.04638

The speed of the wave that is propagated is 10 meters per second.

A wave is a disturbance or variation that gradually conducts electricity from point to point in a medium and can take the form of elastic deformation or a change in pressure, electric or magnetic intensity, electric potential, or temperature

The speed of a wave is determined by the frequency of the wave and its wavelength. In this case, the child is sending pulses down the rope at a rate of 2 pulses per second, so the frequency is f = 2 Hz.

The distance between the pulses is 5 meters, which is the wavelength of the wave, represented by lambda (λ).

The speed of the wave (v) is given by the formula:

v = f * λ

Substituting the values we have, we get:

v = 2 Hz * 5 m = 10 m/s

Answer:

The smallest possible value of the principal quantum number (n) for an electron in an atom is n = 1. This is referred to as the first energy level or the "1s" orbital, and it corresponds to the lowest energy state of an electron in an atom.

Explanation:

In general, the value of n determines the size and energy of the electron orbital. The larger the value of n, the larger the size of the orbital and the higher the energy of the electron. The smallest possible value of n is therefore always 1, and it corresponds to the electron being in its lowest energy state.

The orbital period of this asteroid is approximately 353.55 Earth years.

Kepler's third law states that the square of the orbital period (in years) of a planet or asteroid is proportional to the cube of its semi-major axis (in AU).

Therefore, we can use the following formula to calculate the orbital period:

(T / 1 year)^2 = (a / 1 AU)^3

where;

Plugging in the values for the asteroid at 50 AU, we get:

(T / 1 year)^2 = (50 / 1 AU)^3

Correct option at constant speed is "The push on the box by the student and the push on the student by the box" due to Newton's Third Law.

This is because every force has an equal and opposite reaction force according to Newton's Third Law of Motion. In this case, the student is pulling the rope, which exerts a force on the box, and the box is exerting an equal and opposite force on the student through the rope.

The other options listed do not correspond to a force pair because they either involve a single force acting on an object or two forces that are not equal and opposite. The normal force on the box and the weight of the box, for example, are two forces acting on the same object but are not equal and opposite. Similarly, the weight of the box and the weight of the student are two different forces acting on different objects and are not equal and opposite.

It's important to note that even though the box is moving at a constant speed, there are still forces acting on it. In this case, the force of friction is balancing the force applied by the student, resulting in zero net force and constant velocity.

The ball had a maximum height that was 3.0 meters lower than its initial height (h₀).

Before being thrown down, let's call the ball's initial height h0. The ball's height after it was thrown down and bounced back up is called h1.

After being thrown, the ball takes half as long to reach its maximum height (h1) as it does to bounce back to the ground (2.9 s divided by 2 = 1.45 s).

Using the following equation for vertical displacement under gravity's constant acceleration:

                   y = v₀ × t + (1/2) × a × t²

where:

The initial velocity of the ball, v₀, is negative because it was thrown straight down;

a is the acceleration caused by gravity (9.8 m/s²); and

t is the time it takes for the ball to reach its maximum height (1.45 s).

We can use the equation for velocity under constant acceleration to determine the initial velocity of the ball, v₀ :

                       v = v₀ + a × t

where:

v is the velocity of the ball at time t (0 m/s since it has reached its maximum height)

Combining the two equations:

                     0 = v₀ + 9.8 m/s² × 1.45 s

                 v₀ = -9.8 m/s² × 1.45 s

Substituting the values for v₀ and t into the equation for vertical displacement:

                      h₁ - h₀ = v₀ × t + (1/2) × a × t²

h₁ - h₀ = (-9.8 m/s² × 1.45 s) × 1.45 s + (1/2) × 9.8 m/s² × (1.45 s)²

                       h₁ - h₀ =   -13.8 m + 10.8 m

                           h₁ - h₀

                             = -3.0 m

So, the ball's greatest height above the floor was 3.0 m less than its initial height (h₀).

Answer:

Explanation:To find the change in kinetic energy, we subtract the initial energy from the final energy. This answer in positive because the car gains energy when it increases its velocity.

The energy of the flower pot is potential energy. The potential energy of the flower pot when it weighs 3 N in a height of 300 m is 900 J.

Potential energy of an object is the energy generated by virtue of its position whereas, kinetic energy is the energy generated by virtue of its motion.

Potential energy = mass x gravity x height

Given the weight of the flower pot is 3N. That is the force by gravity. Then displacement = 300 m.

Thus, P = 3 m × 300 m = 900 J.

If the flower pot is placed at a height of 10 m, the potential energy reduces as follows:

Potential energy = 3 x 10 m = 30 J.

Remaining energy is converted to the kinetic energy

The final kinetic energy of the supply spacecraft is [tex]6.4 *10^{11} J[/tex] and final kinetic energy of the supply spacecraft can be found using the work-energy principle.

The work done by the tractor beam force can be found by integrating the force with respect to distance. Since the force is a function of x, we need to express the distance traveled by the spacecraft as a function of x. We know that the spacecraft starts from rest at x = 0 and moves a distance of [tex]4.0 * 10^5 m[/tex], so we have:

[tex]x = 0 + (1/2)ax^2 + 8x[/tex]

We can simplify this expression to:

[tex]x = (1/2)ax^2 + 8x[/tex]

Now we can express the work done by the tractor beam force as an integral:

W = ∫ F(x) dx from [tex]x = 0[/tex] to [tex]x = 4.0 * 10^5 m[/tex]

W = ∫ (ax + 8) dx from [tex]x = 0[/tex] to [tex]x = 4.0 * 10^5 m[/tex]

[tex]W = (1/2) a (4.0 * 10^5)^2 + 8 (4.0 *10^5)[/tex]

[tex]W = 6.4 * 10^{11} J[/tex]

The work done by the tractor beam force is [tex]6.4 * 10^{11} J[/tex].

Since the work done on the spacecraft is equal to the change in kinetic energy of the spacecraft, we have:

W = KE2 - KE

where KE is the initial kinetic energy of the spacecraft, which is zero.

Therefore, the final kinetic energy of the spacecraft is:

[tex]KE2 = W = 6.4 *10^{11} J[/tex]

The value of the resistance is approximately 0.047 kΩ.

What is Resistance?

Resistance is a measure of how much a material or device opposes the flow of electric current through it. Resistance is typically denoted by the letter R and is measured in Ohms (Ω) in the International System of Units (SI).

We can use the formula for the charging of a capacitor through a resistor:

V = V_0 * (1 - e^(-t/RC))

where V_0 is the initial voltage, V is the final voltage, t is the time, R is the resistance, and C is the capacitance.

In this case, the capacitor is charged 71 times per minute, so the time between charges is:

t = 60 s / 71

= 0.845 s

The capacitor is charged to 0.732 of its full voltage, so the fraction remaining is:

1 - 0.732 = 0.268

0.268 = e^(-0.845/RC)

Solving for RC, we get:

RC = -0.845 / ln(0.268) ≈ 1.42 s

Since we know the capacitance C is 33.0 nF, we can solve for the resistance R:

RC = R * C

= 1.42 s * 33.0 nF

= 0.0468 ≈ 0.047 kΩ

Therefore, the value of the resistance is approximately 0.047 kΩ.

The magnitude of the electric field in the region r≤a is zero.

What is Point Charge?

A point charge is a theoretical charge that is assumed to be located at a single point in space, with all of its electric charge concentrated at that point. It is an idealized model that is often used to simplify calculations in electromagnetism. A point charge can be either positive or negative and is characterized by its electric charge, which is a fundamental property of matter. The electric field created by a point charge decreases with distance from the charge, following an inverse square law. The concept of a point charge is often used in electrostatics, where the charge distribution of an object can be approximated as a collection of point charges.

Inside the hollow metal sphere (i.e., for r≤a), the electric field is zero because the excess charge +2Q on the sphere redistributes itself to cancel out the electric field due to the central charge +Q.

This can be shown using Gauss's Law. A spherical Gaussian surface of radius r≤a, centered at the center of the sphere and inside the metal shell, encloses only the point charge +Q. By symmetry, the electric field is radial and has the same magnitude at every point on the Gaussian surface. By Gauss's Law, the total electric flux through the surface is proportional to the charge enclosed by the surface. Since there is no charge inside the surface (because the excess charge on the metal sphere cancels out the charge inside it), the total electric flux through the surface is zero. Therefore, the electric field inside the hollow metal sphere is zero.

Thus, the magnitude of the electric field in the region r≤a is zero.
