D Volcanic and Sedimentary
Answer:
c
Explanation:
I took the k12 test and got it right
A continental slope is a boundary between the Continental crust and Oceanic crust. Therefore, option (C) is correct.
What is a continental slope?A continental slope can be described as the slope between the outer edge of the continental shelf and the deep ocean floor. The continental slope is defined as a cut by submarine canyons in many locations and marks the seaward edge of the continental shelf.
Continental slopes follow the boundary between continental and oceanic crust. The Continental slope has a steepness range from 1 to 25 degrees, the average is 4 degrees.
The continental margin lies between the continental shelf and the abyssal plain and comprises a continental slope that is surrounded by the flatter continental rise. It contains thick sediments deposited by currents from the shelf and slope.
The shelf generally ends at a point of increasing slope known as the shelf break and the sea floor under the break is the continental slope.

What is the most likely reason that nonmetals are electrical insulators?
Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in order to fill their valence shells.
Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.
Since all nonmetals have valence shells that are full, they hold electrons tightly to avoid changing.
Since all nonmetals have valence shells that are completely empty, they do not attract or release any electrons.

Question 3 is weird but I ran out of answers.
is hydrogen a neutral atom or ion
Answer:
Hydrogen is the smallest chemical element. It has one proton and one electron, making it neutral. However, the ions of hydrogen atom are charged species. Thus, the key difference between hydrogen atom and hydrogen ion is that the hydrogen atom is neutral whereas hydrogen ion carries a charge.
Answer:
A normal hydrogen (H) atom does not have any neutrons in its tiny nucleus. That tiny little atom (the tiniest of all) has only one electron and one proton. You can take away the electron and make an ion, but you can't take away any neutrons.

What is the effect of constant stirring on the solubility of solids and liquids?
Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute
In your own words, describe how the energy of a pendulum is changed as it moves through one cycle of its motion. Pls help online school sucks
In a perfect world without air resistance, the top of the swing would have the most potential energy, but the least amount of kinetic energy. As the pendulum falls down, it gains more kinetic energy as it travels faster due to gravitational acceleration but loses more potential energy as it loses height. The total amount of energy in the system (the sum of kinetic and potential energy) stays the same.
The energy of a pendulum is changed from Kinetic to Potential Energy (and vice-versa) when it moves through one cycle of its motion.
What is Kinetic Energy ?The kinetic energy of an object is the energy that it possesses due to its motion and is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
When we move the bob of the pendulum to start the movement you "charge" it with Potential Energy (Gravitational) by varying its position (height) in relation to the ground.
When we release the bob it moves towards the equilibrium position changing Potential into Kinetic Energy (through the movement with Velocity).
At the equilibrium point the bob doesn't stop but goes on up to the same height "re-charging" it with Potential Energy.
The sum of Kinetic (K) and Potential (U) Energy (called Mechanical Energy is always the same:
E = K + U = constant
Therefore, The energy of a pendulum is changed from Kinetic to Potential Energy (and vice-versa) when it moves through one cycle of its motion.

Answer:
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

what did ruthorford discover that thomson did not understand
Answer: Atoms aren't entirely empty space
Explanation:
Rutherford did his scatter experiment to disprove Thomson's Plum Pudding Model. Rutherford shot helium nuclei at a sheet of gold and expected the particles to all go straight through to a sensor. The reason he expected this was because Thomson said that atoms are mostly made of empty space. Not all the particles went through the gold sheet, a lot of them actually reflected back to him. This meant that atoms aren't entirely empty space and something had to deflect the helium nuclei

How does increasing the mass affect the kinetic and potential energy of a pendulum?
Explanation:
Anytime matter is in motion it has kinetic energy. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Both the kinetic energy and potential energy are directly proportional to the mass of the object. Hence, increasing the mass will increase the kinetic and potential energy of the pendulum.
What is kinetic energy ?The kinetic energy of an object is generated by virtue of its motion. Whereas, the potential energy is generated by virtue of its position. hen the object is at rest, the energy is stored in it in the form of potential energy. When the object starts moving, its potential energy starts to converts to kinetic energy.
The kinetic energy of an object is related to its mass and velocity by the equation:
Ke = 1/2 mv²
Potential energy P = mgh
where, g is the acceleration due to gravity and h is the height of the object from the surface.
Hence, both potential energy and kinetic energy are directly proportional to the mass of the object. An increase in mass increase both form of energy of the object.
Therefore, the kinetic and potential energy of the pendulum increases with mass.
