In a computer simulation, Juan moves a magnet (Magnet 1) closer to another magnet (Magnet 2) that cannot move. Which statement accurately describes the change in potential energy?
a
The potential energy does not change because the magnets in the system do not change.
b
The potential energy increases because Magnet 1 moves against the magnetic force.
c
The potential energy decreases because Magnet 1 moves against the magnetic force.
d
The potential energy decreases because Magnet 1 moves in the same direction a
Answer:
C
Explanation:
The potential energy decreases because Magnet 1 moves against the magnetic force. If it was increased it would be kinetic
When Magnet 1 moves against the magnetic force, the potential energy will increase.
Potential energy:
It is the enregy of present in the object or system due to the position of the different parts of the system.
Here, when one magnet bring closer to another magnet the magnetic force will increase.
Therefore, when Magnet 1 moves against the magnetic force, the potential energy will increase.

Answer:
False
Explanation:
It depends on the density of an object, not the wight.
Answer: it’s false
Explanation: false
A ship is heavy, but it sinks, right? If something sinks or floats is based off of its density.
Things that are less dense than the liquid they are on will float

B. Matter moves at right angles to the direction of a longitudinal wave, and at right angles to the direction of a transverse wave.
C. A longitudinal wave does not need matter through which to travel, while a transverse wave does.
D. A longitudinal wave needs matter through which to travel, while a transverse wave does not.
Explain the relationship between mass and gravity
Answer:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Explanation:
i did some research and this is what I got. hope it helps.
Mass is the amount of matter present in an object. All objects in the universe attract every other object in the universe. This force is called the gravitational force or gravity. This force is proportional to the product of the masses of the two objects and inversely proportional to the square of distance between them.
More is the mass, more is the gravitational force or gravity

Isaac Newton believed that light was made of particles.
What is light?Light or visible light is electromagnetic radiation that can be perceived by the human eye.Visible light is usually defined as having wavelengths in the range of 400 – 700 nanometers (nm), corresponding to frequencies of 750 – 420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths)Given is the theory of light by Sir Isaac Newton.
Corpuscular Theory →
According to Newton's corpuscular theory of light, light is composed of very tiny, elastic and rigid particles called corpuscles. When this corpuscles enters into our eye, we get the sensation of light or sensation of vision.Therefore, Isaac Newton believed that light was made of particles.

the amount of water in cirrus clouds
the amount of water that has evaporated into the air

the amount of water vapor in the air compared to the amount the air can hold
Answer:
It is D
Explanation:
edge unit test review thing
Relative humidity measures the amount of water vapor in the air compared to the amount the air can hold at a specific temperature. The correct option is option (4).
It is a measurement of the moisture content in the air relative to its capacity to hold moisture.
The relative humidity is expressed as a percentage and indicates how close the air is to being saturated with water vapor. A higher relative humidity value means that the air contains a larger amount of water vapor compared to its capacity at that temperature.
Therefore, It is important to note that relative humidity is not a direct measure of the amount of water in specific cloud types or the amount of frozen water that has condensed from the air. The correct option is option (4).

A student has designed a circuit with one battery, two light bulbs, and two switches, pictured to the left. She would like for each switch to control one light bulb, so that when one switch is open and the other is closed, one of the light bulbs will remain lit. From the image, we can see that neither light bulb is lit, even though one of the switches is closed. What is the error the student made? Your explanation should include a discussion of the flow of electrons in the circuit.
Answer:
The bulb is not powered because the negative end of the battery is not connected to the electric current,making it dysfunctional. The electrons have to flow through the positive and negative ends of the battery in order for it to work.
Hope this helps.
The mistake of the student is that the circuit was left open hence current can not flow across in the circuit.
What is a circuit?A circuit is designed for the flow of current. In this case, we know that current can only flow when the circuit is closed. A closed circuit implies that the switch has been closed.

The dog's foot prints are overlapping the shoes that are overlapping the tire marks from 3 different tires, if the dog is his seeing dog then it would make sense that the dog's foot prints are next to his and they're going in the same direction, and since the dog's footprints overlap the others it means that they were there last.
People were confused so I'll resay it. The dog is the nephew's seeing dog, so he walks beside him. And if the dog's foot prints are overlapping all of the other's, that means the dog was there after all of the rest of them, and if the nephew is with the dog then the nephew was there last.
Your 20-kg brother Mickey is on a see-saw. If you have a mass
of 50-kg and are 2 meters away from the center of the see-
saw, how far out would Mickey have to sit if he wants to apply
the same force onto you that you apply onto him? meters
Answer:
5
Explanation:
To apply the same force as the person, the brother have to sit at a distance of 5 m.
What is meant by torque ?
Torque is defined as the rotational analogue of force. It is the cross product of force and the displacement of the object.
Here,
Mass of the person, m₁ = 50 kg
Mass of the brother, m₂ = 20 kg
Distance of the person, d₁ = 2 m
For the see-saw to get balanced, the torque applied by the two persons each side must be equal.
τ₁ = τ₂
where τ₁ is the torque applied by the person and τ₂ is that applied by the brother.
So, F₁d₁ = F₂d₂
m₁g x d₁ = m₂g x d₂
m₁d₁ = m₂d₂
Therefore, distance of the brother,
d₂ = m₁d₁/m₂
d₂ = 50 x 2/20
d₂ = 5 m
Hence,
To apply the same force as the person, the brother have to sit at a distance of 5 m.

Explanation:
As the Sun heats the ocean, the water evaporates, turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water. This process is called condensation. Drops of water fall back down to Earth again as precipitation, which can be in the form of rain, snow, sleet, or hail
three phases of water cycle are
