Answer in Explanation form
A wave carries its energy without transporting matter. Waves are seen to move into an ocean or lake, yet the water always returns to its resting position.
A wave transports energy, but not matter. Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter.
What is a wave?A wave is a disturbance that travels through space and matter, transferring energy from one place to another. Waves can take many forms, including mechanical waves (such as sound waves and seismic waves) and electromagnetic waves (such as light waves and radio waves).
Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter. For example, sound waves can transmit energy through the air without moving any air molecules, and light waves can transmit energy through empty space without moving any particles. However, waves can still have an impact on matter by interacting with it, such as when a wave causes an object to vibrate or when a wave of light is absorbed by a substance.

Explanation:
scientist created diagram X to represent the molecules of a kind of gas in a closed container. Diagram Y represents the molecules in the container after the size of the container was reduced. The temperature in the container was not changed. What most likely happened to the system when the scientist changed the size of the container? A. Matter was added. B. Matter was removed. C. The pressure increased. D. The pressure decreased.
The most likely outcome when the scientist changed the size of the container is that the pressure increased.
Option (C) is correct.
When the size of the container is reduced while keeping the temperature constant, the gas molecules experience a decrease in volume. According to Boyle's law (P₁V₁ = P₂V₂), if the volume decreases, the pressure of the gas will increase.
Diagram X represents the initial state with larger volume, and diagram Y shows the final state with reduced volume. Since the temperature remains constant, the pressure must change to counterbalance the change in volume.
As the volume decreases, the gas molecules have less space to move around, and they collide more frequently with the container walls. This increased collision rate results in a higher pressure exerted by the gas on the container walls.
Hence, the most likely outcome when the scientist changed the size of the container is that the pressure increased, which corresponds to option C.

What substances can be released in a volcanic eruption
Why does an object with less mass move faster after a collision with an object with more mass?
Answer:
if two objects of different mass have the same momentum, then the object with the least mass has a greater velocity
The greater the force that is applied to an object of a given mass, the more the object will accelerate
Explanation:
For example, doubling the mass of an object results in only half as much acceleration for the same amount of force
Write a paragraph comparing protons, neutrons, and electrons. Be sure to include mass, location, and electric charge.
Answer:
Explanation:
Dalton's Atomic Theory explained a lot about matter, chemicals, and chemical reactions. Nevertheless, it was not entirely accurate, because contrary to what Dalton believed, atoms can, in fact, be broken apart into smaller subunits or subatomic particles. We have been talking about the electron in great detail, but there are two other particles of interest to us: protons and neutrons. We already learned that J. J. Thomson discovered a negatively charged particle, called the electron. Rutherford proposed that these electrons orbit a positive nucleus. In subsequent experiments, he found that there is a smaller positively charged particle in the nucleus, called a proton. There is also a third subatomic particle, known as a neutron.
Protons, neutrons, and electrons are fundamental particles that constitute the building blocks of atoms.
Protons and neutrons are found in the nucleus, the central core of the atom, whereas electrons are located in electron shells surrounding the nucleus. Protons carry a positive electric charge and have a mass of approximately 1 atomic mass unit (amu).
Neutrons, on the other hand, are electrically neutral, meaning they have no electric charge, but they also have a mass of about 1 amu. Electrons, which are much smaller than protons and neutrons, have a negligible mass of approximately 1/1836 amu and bear a negative electric charge that exactly balances the positive charge of protons, resulting in an overall neutral charge for the atom. The combination of these three particles determines an element's chemical properties and behavior in chemical reactions.

What is the function of peristalsis?
Multiple choice question.
A)
to move food through the digestive system
B)
to remove excess liquid from the body
C)
to chemically digest food to release nutrients
D)
to absorb nutrients into the blood
Answer: A
Explanation
The digestive tract carries out the function of peristalsis by moving food through the system. Peristalsis also removes excess liquid from the body. Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis. Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.

Answer:

Explanation:
Friction is similar to drag. Like drag it acts on an object in the opposite direction from the object’s motion.
How does the friction slow motion?
Answer:
• Friction is a force that occurs when two surfaces slide past
one another.
• The force of friction opposes the motion of an object,
causing moving objects to lose energy and slow down.
• When objects move through a fluid, such as air or water, the
fluid exerts a frictional force on the moving object. The
frictional force from a fluid is called a drag force.
• Friction examples: tires skidding to a stop on a road,
sandpaper rubbing against wood, air pushing against the
nose of an airplane
• Friction drag force causes objects to slow down as they move through a
fluid, such as air or water.
• Drag force depends primarily on the following variables:
– Cross‐sectional area of an object moving through the fluid
– Speed of moving object
– Density of the fluid
– Drag coefficient (determined by experiments; related to the shape of
the object)
• Drag force is especially dependent on the speed of an object. As an
object’s speed increases, the drag force from the fluid increases
exponentially.
• For example, when you drive at high speeds, the frictional force of air on
the car increases and fuel economy decreases

My project is on candles and wax.
If it'll help, here is my hypothesis: If the waxes being tested are beeswax, palm wax, paraffin wax, and soy wax, then the palm wax should burn the slowest and last the longest.
Answer:
OK, you can say:
Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in organic, nonpolar solvents. Natural waxes of different types are produced by plants and animals and occur in petroleum.

Brainliest me
If my skater begins at a height of 5 meters, then the skater will have enough total potential energy to successfully complete the skate park ramp from start to finish.
If my skater starts at a height of 5 metres, he or she will have enough total potential energy to complete the skate park ramp from beginning to end. Potential energy is a physics notion that is affected by an object's height and mass. Because of its position in a gravitational field, an object at a specific height above the earth has potential energy.
The skater has a particular amount of potential energy connected with their starting height of 5 metres. As they go down the ramp, this potential energy is turned into kinetic energy, or motion energy. As the skater moves down the ramp, their speed rises, as does their kinetic energy.
