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.

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.
can someone please expain newton's second law of motion in a paragraph please? i'll give brainliest
Answer:
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

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 true about radioactive isotopes of an atom?
They do not break down.
They break down quicker than stable isotopes.
They undergo radioactive decay to form larger isotopes.
They break down to form heavier isotopes.
Answer:
They break down quicker than stable isotopes.
Explanation:
I hope this helps
Have a blessed day
The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.
What is radioactive isotope?A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.
Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.
Therefore, option C that is, they break down quicker than stable isotopes is correct.

What connections can you make between Albinism in humans and Albinism in animals?
Answer:
the connections you can make between albinism in humans and in animals is that animals can appear in white or pink or an animal will have pink eyes, nail, skin/scales while an human will also have nails and skin, the human body can't have scales and a human can't really have pink eyes
Hope this helps :p
Explanation:
dont read unless you need some examples...
Melanin is produced by cells called melanocytes, which are found in your skin, hair and eyes. Albinism is caused by a mutation in one of these genes. Different types of albinism can occur, based mainly on which gene mutation caused the disorder.This genetic condition gets passed to offspring when both parents carry the recessive gene. When albinism is present, the animal can appear white or pink. An animal can be completely albino (pure albino) or have leucism. Pure albino animals will have pink eyes, nails, skin and/or scales.Ocular albinism type 1 is inherited in an X-linked pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome , one of the two sex chromosomes

Does a wave transport energy, matter, or both? Explain your answer in 1-2 sentences (Will give brainliest)
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.
