A passive continental margin has a continental rise, while an active margin does not. Therefore, option A is correct.
What is passive continental margin?Where there is no plate border to mark the transition from land to sea, this is known as a passive continental margin.
A good example is the east coast of the United States, where the plate boundary is a distance from the shore along the mid-Atlantic ridge. Little geological activity occurs along passive borders.
Volcanoes, mountain belts, and earthquakes all identify active margins. They lack a continental uplift and an abyssal plain, in contrast to passive margins.
The Pacific and North American Plate boundaries are visible along the west coast of the United States, which is an example of an active margin. Where there is no plate border to mark the transition from land to sea, this is known as a passive continental margin.
Thus, option A is correct.

Rutherford's model of atoms describes the atom as a tiny, dense particle which contains a positively charged nucleus with electrons which are negative charged moving in orbitals.
What is Rutherford's model?Rutherford's model of atoms described the atom as a tiny, dense, positively charged core particle which is called a nucleus, in which nearly all the mass of the atom is concentrated, around within the nucleus which the light, negative constituents, called electrons, circulate at some specific distance, much like the planets which are revolving around the Sun.
During the Rutherford's experiment, the alpha particles are bombarded on the thin piece of gold foil. The alpha particles were expected to pass easily through this gold foil.

Describe a way that gravity influenced the formation of the solar system, with the planets orbiting the sun.
Gravity influenced the formation of the solar system, with the planets orbiting the sun.
What is Gravitational Force ?Gravitational force is force of attraction between two masses. Gravitational force(F) between two bodies is directly proportion to the product of masses(m₁,m₂) of two bodies and inversely proportional to square of distance(r) between them. mathematically it is written as,
F [tex]\alpha[/tex] m₁.m₂
F [tex]\alpha[/tex] 1/r²
F = G m₁,m₂÷r²
where G is gravitational constant, whose value is 6.6743 × 10⁻¹¹ m³ kg-1s⁻².
Force is expressed in Newton N in SI unit. its dimensions are [M¹L¹T⁻²].
According to Kepler's first law of motion, every planet is moving in an elliptical orbit with sun has situated at one of the foci of the orbit.
when a planet moves in the orbit around the sun, it moves in a stable orbit. in this orbit , centripetal force is equal to centrifugal force, in this case centripetal force appears as gravitational force. Means Gravitational force between sun and planet balances the centrifugal force which is outwards. In such a way gravity influenced the formation of the solar system.
Hence gravity plays crucial role in the formation of solar system.

When electricity moves through a metal wire, the wire is
A. A resistor
B. A conductor
C. an insulator
D. a power supply
When electricity moves through a metal wire, the wire is option B. A conductor.
What is a Conductor?Conductors are materials that allow electricity to flow easily through them. An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow and causes resistance.The flow of electricity through a wire is the flow of electrons. An electron is a negatively charged subatomic particle. In electrical conductors, the flow of electricity results from the movement of electrons from one atom to the next.To learn more about conductors, refer to: https://brainly.com/question/27533161

Define potential energy (PE)
Answer:
Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system.
This form of energy has the potential to change the state of other objects around it, for example, the configuration or motion.
Various forms of energy can be grouped as potential energy.
Each of these forms is associated with a particular kind of force acting in conjunction with some physical property of matter (such as mass, charge, elasticity, temperature etc).
For example, gravitational potential energy is associated with the gravitational force acting on object's mass; elastic potential energy with the elastic force (ultimately electromagnetic force) acting on the elasticity of a deformed object; electrical potential energy with the coulombic force; strong nuclear force or weak nuclear force acting on the electric charge on the object; chemical potential energy, with the chemical potential of a particular atomic or molecular configuration acting on the atomic/molecular structure of the chemical substance that constitutes the object; thermal potential energy with the electromagnetic force in conjunction with the temperature of the object.
For an example of gravitational potential energy, consider a book placed on top of a table.
To raise the book from the floor to the table, work must be done, and energy supplied. (If the book is lifted by a person then this is provided by the chemical energy obtained from that person's food and then stored in the chemicals of the body.) Assuming perfect efficiency (no energy losses), the energy supplied to lift the book is exactly the same as the increase in the book's gravitational potential energy.
The book's potential energy can be released by knocking it off the table.
As the book falls, its potential energy is converted to kinetic energy.
When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
Explanation:
Answer:
potential energy is basically stored energy

A spring has a force constant of 40000 N/m.
How far must it be stretched for its potential energy to be 42 J?
Answer in units of m
Answer:
0.05m
Explanation:
Given parameters:
Force constant of the spring = 40000N/m
Potential energy = 42J
Unknown:
Extension = ?
Solution:
To solve this problem, use the expression below:
E.PE = [tex]\frac{1}{2}[/tex] k e²
k is spring constant
e is the extension
42 = [tex]\frac{1}{2}[/tex] x 40000 x e²
e = 0.05m

A. The energy stored in Harry's musclesbwas destroyed.
B. The energy was returned to Harry's muscles
C. Kinetic energy changed to potential energy.
D. Potential energy changed to kinetic energy.
Answer:
C. Kinetic energy changed to potential energy.
Explanation:
The kinetic energy is converted to potential energy when he reaches the top of the hill.
As with every system, energy is neither created nor destroyed but transformed from one form to another.
This is from the law of conservation of energy.
Kinetic energy is produced when Harry moves the up the hill. As he reaches the top of the hill and comes to rest, potential energy is formed.
Potential energy is the energy due to the position of a body.
