The name of the gravitational force acting on a mass on the surface of the Earth is gravity larger masses have stronger  gravitational fields. If the field is stronger on a planet, objects will accelerate towards the ground at a faster  rate.​

Gravity is a force that attracts two objects with mass towards each other. It is the force that gives weight to physical objects and is what keeps us grounded on the surface of the Earth.

Therefore, The strength of the gravitational field depends on the mass of the object creating the field and the distance from the object. The larger the mass of the object, the stronger the gravitational field. The closer an object is to the source of the gravitational field, the stronger the field will be.

The name of the gravitational force acting on a mass on the surface of the Earth is weight.

Larger masses have greater  gravitational fields.

If the field is stronger on a planet, objects will accelerate towards the ground at a constant rate.​

Gravitational force is described as the force of attraction between all masses in the universe more especially the attraction of the earth's mass for bodies near its surface.

This is better explained by Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

The gravitational acceleration on planet X is about 0.405 times that of Earth's.

The period, T, of a simple pendulum is given by:

T = 2π√(L/g)

where L is the length of the pendulum and g is the gravitational acceleration. If we assume that the length of the pendulum remains constant between Earth and planet X, we can write:

T_X/T_Earth = √(g_Earth/g_X)

where T_X is the period on planet X and T_Earth is the period on Earth. We can substitute the given values to get:

1.530 s/2.243 s = √(g_Earth/g_X)

Squaring both sides of the equation, we get:

(g_Earth/g_X) = (2.243/1.530)^2 = 2.467

Therefore, the ratio of g_X/g_Earth is:

g_X/g_Earth = 1/g_Earth/g_X = 1/2.467 = 0.405

So the gravitational acceleration on planet X is about 0.405 times of Earth's.

Faraday's Law states that a change in magnetic flux induces an electromotive force (EMF) in a conductor, while Lenz's Law describes the direction of the induced EMF. According to both laws, when the north pole of a bar magnet moves toward a coil of wire, an induced current will flow in a direction that opposes the change in magnetic flux.


1. Faraday's Law: This law states that the electromotive force (EMF) induced in a conductor is proportional to the rate of change of magnetic flux through the conductor. Mathematically, it is represented as EMF = -dΦ/dt, where Φ is the magnetic flux and t is time.
2. Lenz's Law: This law determines the direction of the induced EMF and states that the induced EMF will act in such a way as to oppose the change in magnetic flux that caused it. It is a consequence of the conservation of energy.
3. Combining Faraday's and Lenz's Laws: When the north pole of a bar magnet is moved toward a coil of wire, the magnetic flux through the coil increases. According to Lenz's Law, the induced current will flow in a direction that opposes this increase in magnetic flux. This means that the induced current will create its own magnetic field with a south pole facing the approaching north pole of the bar magnet, opposing the change in magnetic flux.

Answer:

elastic potential energy

Explanation:

The situation above shows an example of an "elastic potential energy." This type of potential energy depends on the force being applied to the elastic object.

In the situation above, the elastic object is the rubber band. The resultant energy is then being stored until such time that this object will be freed. Once this happens, the elastic object will revert to its original form and the rock will soar (be released).

The amount of energy that is being stored largely depends on the distance of the "stretch" being applied to the object. It is said that the greater the force, the greater the stretch and the greater the distance covered by the rock (and vice-versa).

When light enters and leaves the prism, it changes direction

When light travels through a triangular prism, these hues are frequently seen. The prism separates the white light into its individual colors, which are red, orange, yellow, green, blue, and violet. Dispersion is the process through which visible light is divided into its various colors.

What causes a rainbow to occur when white light passes through a prism?

The various colors of visible light are separated using a prism. Different wavelengths of light bend at different angles as they slow down and slow down through the prism. Through this, light is divided into several wavelengths, creating a rainbow of hues.

This is how dispersion of light (white light), where it breaks into its seven basic colors, occurs when it passes through a prism. When subjected to refraction, white light separates into its component colors because various colors of different wavelengths experience varying degrees of divergence.

Violet, the hue with the greatest frequency in visible light, also has the maximum amount of energy. Red, which has the lowest visible light frequency, has the least energy.

B. What are the base units of electric current?

To find out that the electric current is a vector or scalar quantity, Tim should ask what is the symbol for electric current. Hence, option C is correct.

A physical quantity whose size is a complete description of it. Volume, density, speed, energy, mass, and time are a few examples of scalars. Other quantities, like as force and velocity, are referred to as vectors since they have both magnitude and direction.

Real numbers that are typically positive but not always characterize scalars.

In physics, a vector is a quantity with both magnitude and direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity. A vector does not have position, while having magnitude and direction. In other words, a vector's shape is unaltered if it is shifted parallel to itself as long as its length is unaltered.

g = (6.67 * 10⁻¹¹ * 3 * 10³ * 4.5 * 10³) / (1.5)²

g = [(6.67 * 3 * 4.5) * (10³⁺³⁻¹¹)] / 2.25

If the ball exits the track while undergoing an acceleration of 3g, 55.4m away from the base of the track does the block land

Acceleration ac = V²/R = 3g

V = √3gR

By using kinematic equation for vertical motion of ball,

S = u t  + 1/2 gt²

S = 2R, U = 0

t = √4R/g

Horizontal distance is given by

D = vt = √3gR × √4R/g

D = 2√3 R

D = 55.4m

To get the equation for the horizontal distance, one can rearrange the slope percent equation. Divide both sides by run to rewrite the equation's terms. The slope percent is applied to both sides. Horizontal distance is calculated as run = (rise 100) / slope%. When two points are separated by a horizontal distance, the slope is zero percent.

They combined in groups to make protons, neutrons, and their antiparticles. The correct option is A.

They combined in groups to make protons, neutrons, and their antiparticles. During the particle era, which occurred immediately after the Big Bang, the universe was filled with a hot soup of particles including quarks. As the universe cooled, the quarks combined in groups of three to form protons and neutrons, which are the building blocks of atoms. This process is known as hadronization. The antiparticles of these hadrons were also formed during this time. So, in summary, the quarks did not evaporate, freeze out, or combine to form electrons, neutrinos, or W and Z bosons, but rather they combined in groups of three to form protons, neutrons, and their antiparticles.

During the particle era, quarks existed freely, but as the universe cooled, they eventually combined in groups of three to form particles like protons and neutrons.

When electrons are emitted from the cathode, they can have zero velocity, one velocity, or a range of velocities depending on the conditions under which they are emitted.

For example, in a vacuum tube, electrons are emitted from the cathode due to thermionic emission and they typically have a range of velocities.

However, in a photoelectric effect experiment, electrons are emitted from the cathode due to the absorption of photons and they typically have a well-defined velocity determined by the energy of the incident photons.

Similarly, in a field emission experiment, electrons are emitted from the cathode due to a high electric field and they typically have a high velocity.

Therefore, the velocity of the electrons emitted from the cathode depends on the mechanism of emission and the conditions under which they are emitted.

The electric field strength is approximately -3.34 × 10^29 newtons per coulomb (N/C).

To determine the electric field strength, we can use the following equation that relates the change in speed of a charged particle to the electric field strength:

Δv = a * Δt

Where:

Δv is the change in velocity (speed) of the electron

a is the acceleration of the electron

Δt is the time taken

Given:

Initial velocity (v1) = 2.0 × 10^7 m/s

Final velocity (v2) = 4.0 × 10^7 m/s

Distance (d) = 1.4 cm = 0.014 m

The change in velocity can be calculated as:

Δv = v2 - v1

Δv = (4.0 × 10^7 m/s) - (2.0 × 10^7 m/s)

Δv = 2.0 × 10^7 m/s

We can rearrange the equation to solve for acceleration (a):

a = Δv / Δt

To find the time (Δt), we can use the equation:

d = (1/2) * a * Δt^2

Rearranging this equation to solve for Δt:

Δt = sqrt((2 * d) / a)

Substituting the given values:

Δt = sqrt((2 * 0.014 m) / (2.0 × 10^7 m/s))

Δt = sqrt(1.4 × 10^(-8) s^2 / m^2)

Δt = 3.74 × 10^(-4) s

Now we can calculate the acceleration (a):

a = Δv / Δt

a = (2.0 × 10^7 m/s) / (3.74 × 10^(-4) s)

a = 5.35 × 10^10 m/s^2

Finally, we can find the electric field strength (E) using the equation:

E = a / q

Where q is the charge of the electron. The charge of an electron is approximately -1.6 × 10^(-19) coulombs.

E = (5.35 × 10^10 m/s^2) / (-1.6 × 10^(-19) C)

E ≈ -3.34 × 10^29 N/C

The electric field strength is approximately -3.34 × 10^29 newtons per coulomb (N/C).
