Which is an example of an object increasing its kinetic energy
Question 3 options:
an airplane after landing on a level runway.
a rocket before launch.
a train stopped at the station.
a mouse running faster after spotting a cat.
Answer:
The answer to this question is the A choice. A rocket before launch.
Explanation:
In the definition of kinetic energy, it says: In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It 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.

What is the mass and volume of the nucleus relative to the size of the atom?
Answer:
The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.

A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.
A person would weight more on Neptune than on planet earth because the gravitational force in neptune is more.
What is gravitational force?Gravitational forces is a kind of attraction force which is present between two objects of masses.
Gravitational force on the neptune planet is more as compared to the gravitational force on the earth. So the mass of any object present in the neptune is more than the earth.
Hence a person would weight more on Neptune than on planet earth because gravitatinal force in neptune is more.

What is atomic mass made of?
Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

_____________________________________Best Regards,'Borz'Which best explains how convection affects the atmosphere
Answer:
The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds

The identity of the element shown in the model above is determined by the number of -
Answer:
The number of protons or electrons in its atomic structure
Explanation:
Elements are substances which constitute the building block of matter. The smallest particles of elements that can ever exist are known as atoms. Atoms of different elements are different in their structure properties. This difference is due to to the number of sub-atomic particles present in the atom of each element.
The three sub-atomicparticles are protons, neutrons and electrons. Protons and neutrons are present in the nucleus of an atom, while the electrons revolve around the nucleus in orbits. The identity of each element is determined by the number of protons present in the atomic nucleus of that element. This is known as the atomic number of that element. For neutral atoms, the proton number is equal to electron number.
For the given element, the electron and proton number are respectively 4, therefore, the atomic number of the element is 4. The element with atomic number 4 is Beryllium.

What is depicted as the yellow arrows in the following image? (Using a scientific vocabulary word we learned in class and provide its definition) Which makes a bigger current- faster moving electrons or slower moving electrons?
Answer:
Electric Current
Explanation:
The yellow arrows in the following image depict electric current. Electric current is defined as the continuous flow of electrons in an electric circuit. Electrons present in the conducting material which move from one to another atom randomly from the negative terminal through the connecting wires and back to the positive terminal.
Faster moving electrons make a bigger current because faster moving electrons collide more with each other that generates more heat which results into a higher current.
Hence, The yellow arrows in the following image depict electric current and Faster moving electrons make a bigger current.
The yellow arrow in the diagram shows the flow of electrons.
Current is defined as the flow of electrons in a circuit. The yellow arrows represents the direction of the flow of electrons in the circuit. The battery provides the potential difference that drives the flow of electrons through the wire.
Since current has to do with the movement of electrons in a circuit, the faster the movement of the electrons, the bigger the current.

I need to someone to explain the whole being of Chemistry. I do not understand a single thing, nothing makes sense to me. Literally, I'm going to fail this class because I do NOT understand a single thing taught to me. Maybe it's because I was mistakenly put into Chemistry Pre AP instead of on level but it's so hard and- I just do not get it.
Answer:
Explanation:
In Pre-AP Chemistry, the development of models to explain their macroscopic observations is a primary means through which students develop an understanding of the molecular world.
You will be forced to think and apply concepts to new situations, and even derive your own theories from application. This is excellent preparation for the higher levels of thinking required in college.
Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.
