this is for science class Gravity and Mass vs. Weight Notes
Answer:
Explanation:
There are two factors that affect gravity: mass and distance.
Law of Gravity: Every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Gravity: the force by which each object draws all the other objects towards its center.
Gravity is affected by mass and distance.
Everything with mass has gravity.
The more mass an object has, the more gravity it has.
The farther you are from the source of gravity, the lesser of gravity you will feel.
In space, your weight will read 0 and the objects in space are hard to move due to the different gravitational forces acting upon each object from different areas.
Weight: Weight is the force of gravity on an object.
Weight is completely dependent on gravitational force acting on an object.
The more gravity there is, the more weight an object will have.
Mass and weight are not the same.
Mass does not change because it is the amount of matter in an object which does not change no matter where the object is. However, weight changes because it is the effect of gravity on an object.
In order to find weight, use the formula W=mg where W is the weight, m is the mass and g is the gravitational force.
What happens to the compass needle as you move the compass around?
A.The compass needle always points north
B.The compass needle points in random directions.
C.The compass needle follows the pattern of magnetic field lines
D.THE compass needle's north pole always points to the north pole of the magnet
When the compass needle as you move the compass around, Then the compass needle follows the pattern of magnetic field lines. The correct option is C.
What is the pattern of magnetic field lines?
Magnetic field lines are imaginary lines used to represent the direction and strength of the magnetic field around a magnet or a current-carrying wire. The pattern of magnetic field lines depends on the shape and orientation of the magnet or the wire, as well as the direction and strength of the magnetic field.
The magnetic field lines around a magnet emerge from the north pole and loop back into the south pole in a continuous path. They are always closed loops, meaning they do not begin or end anywhere but instead form a continuous path around the magnet. The magnetic field lines are closer together near the poles of the magnet, indicating a stronger magnetic field in those regions. They become less dense as they move further away from the poles, indicating a weaker magnetic field in those regions.
Here in the question,
When a compass is moved around, the compass needle aligns itself with the direction of the magnetic field lines in the vicinity. Magnetic field lines are the paths that a small compass would follow if it were placed at various points around a magnet. They indicate the direction of the magnetic field at each point.
The compass needle has a north-seeking pole and a south-seeking pole. The north-seeking pole of the compass needle aligns itself with the direction of the magnetic field lines, which are oriented from the north pole of a magnet to the south pole. This means that the north-seeking pole of the compass needle will point towards the south pole of a magnet, while the south-seeking pole of the compass needle will point towards the north pole of the magnet.
Therefore, as the compass is moved around a magnet or any other magnetic field, the compass needle will follow the pattern of the magnetic field lines, and the north-seeking pole of the compass needle will always point towards the south pole of the magnet or the magnetic field source.

Benefits from fission as energy
Answer:
It can provide cheap energy resources for the planet. ...
It offers a low-emission energy solution. ...
It works for extended periods of time. ...
It is a reliable source of energy. ...
It provides high concentrations of energy. ...
It has the lowest annual mortality rate of any energy resource.
Explanation:
Explanation:
Low-cost energy
Although building nuclear power plants has a high initial cost, it’s relatively cheap to produce energy from them and they have low operating costs.
Reliable
One of the biggest benefits of nuclear energy is that it is a reliable power generation source.
Zero-carbon emissions
Nuclear power reactors do not produce any carbon emissions. This is a huge advantage over traditional sources of energy, like fossil fuels, which releases tons of carbon dioxide into the atmosphere.
Nuclear fusion is the holy grail of harnessing energy. If we can learn to control atomic fusion (the same reactions as those that fuel the sun), we could practically have unlimited energy.
High energy density
It is estimated that the amount of energy released in a nuclear fission reaction is ten million times greater than the amount released when burning fossil fuels
Why is it important for the path of a circuit to be circular?
Answer:
When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.

If a professional football player ran at you and collided with you, what would happen? Why? Use the terms force, mass, and velocity in your explanation.
Answer:
the force of the football player would cause you to fall over and possibly get a concussion because the football players mass is probably more than yours and the velocity of the football player would cause you to fall over or in football terms "get tackled"
Explanation:
Explanation:
Newton stated within his first law of motion that any object of mass at rest (velocity, designated as v, is zero) will tend to stay at rest, and any object in motion (velocity is not zero) will tend to stay in motion at the same speed and direction (acceleration, designated as a, is zero), unless acted upon by a force. Applied to football collisions, the more massive a football player (the more he weighs), the less likely he is to be slowed down, sped up, or diverted by an outside force, such as opponents. The first law is often called the law of inertia because the term inertia means the resistance to motion. For instance, the quarterback who desires to score a touchdown when very near to the goal line will often use the quarterback-sneak. In this scenario, the interior offensive line of players is used as a massive wall to block the defensive line so the quarterback can sneak around or over his men who are very resistant to being moved back.
A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?
Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
How can you use the movement of molecules to determine when a phase change has occurred?
Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

Recording the location of a star requires a measurement of:
altitude
azimuth
time
all of the above
To accurately record the location of a star, you would typically need to measure the altitude, azimuth, and time.
Altitude: The altitude refers to the angle above the horizon at which the star is located. It is measured vertically from the observer's position.
Azimuth: The azimuth refers to the horizontal angle or direction in which the star is located. It is measured clockwise from a reference direction, often north.
Time: Recording the time of observation is crucial for celestial navigation and astronomy. It helps determine the position of the star relative to Earth's rotation and allows for calculations related to the star's apparent motion.
Therefore, to precisely record the location of a star, you would need to measure the altitude, azimuth, and time.
