Answer:
The rule to remember is that opposites attract. Every magnet has both a north and a south pole. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.

During class, you jump up and run over to get a ruler because you love making graphs. This is an example of acceleration.
True or False?
Answer:
The answer is true
Explanation:
Because acceleration is the change in velocity like running and walking for example. You move with more velocity because you are running.

Explain how kinetic energy and potential energy change as a rollercoaster moves up and down hills on its track.
Explanation:
Before the roller coaster starts moving, it is at rest and energy at rest is potential energy. As the roller coaster moves the potential energy is converted to kinetic energy as kinetic energy is energy in motion. As it gets to the top of a hill it assumes a rest position from a height for a short time and as it comes down the potential energy is converted again to kinetic energy. This continues for the whole ride until it comes to an end.
Velocity is speed in a certain direction.

diagram below shows how air movement near the equator can form
thunderstorms.
Using the image below, determine which description correctly explains
which heat transfer is shown and why.
A. decrease in relative humidity loers the temeprature therefore creting
thunderstorms
B. heating by energy from the Sun causes the cooling and waring of air and ocean
currents

D. warming in the upper atmosphere leads to thunderstorms in the troposphere
Answer:
D. Warming in the upper atmosphere leads to thunderstorms in the troposphere
Explanation:
The image is showing the circulation of air, which is heat rising and cold air falling. Also, thunderstorms occur in the troposphere.

Answer:
Asteroids are objects made of clay and silicate that orbit the sun but are too small to be considered planets.
Most asteroids revolve around the sun in an orbit between those of Mars and Jupiter.
They form a wide band called the Asteroid belt.
Other asteroids have orbits that cross Earth’s orbit. These asteroids are called Earth-crossers.
Asteroids probably consist of matter that never agglomerated into a planet when the solar system was forming.
The comet’s core is composed of ice and dust.
Comets heat up and begin to change from a solid to a gas as they approach the sun.
The matter surrounding a comet’s core is vaporized and forms a very bright halo of ice or dust not sure, and an enormous cloud of dust or gasses not sure envelopes the head of the comet.

PLEASE SOMEONE HELP ME ILL GIVE THE PERSON BRAINLIEST
If a ball was dropped from the Empire State Building, or from the Golden Gate Bridge, or from the Statue of Liberty, and from the top of a table, tell Gravitron how long it would take each of the balls to hit the bottom. Fill in the table below:
Dropped from:
Time (seconds)
Empire State Building
Golden Gate Bridge
Statue of Liberty
If a ball is dropped from different heights, it will take different amounts of time to hit the ground due to the force of gravity. The time it takes for an object to fall is determined by its initial height and the acceleration due to gravity.
Let's consider the three different heights mentioned in the question: the Empire State Building, the Golden Gate Bridge, and the Statue of Liberty. To calculate the time it would take for a ball to hit the ground from each of these heights, we need to use a formula.
The formula to calculate the time it takes for an object to fall is:
t = √(2h/g)
where t is the time, h is the initial height, and g is the acceleration due to gravity (which is approximately 9.8 m/s^2).
Now, let's fill in the table with the calculated times:
Dropped from: Empire State Building
Time (seconds): t = √(2h/g)
To calculate the time, we need to know the height of the Empire State Building. The Empire State Building is approximately 443.2 meters tall. Plugging in the values into the formula:
t = √(2 * 443.2 / 9.8) ≈ √(90.4) ≈ 9.51 seconds
So, it would take approximately 9.51 seconds for a ball to hit the ground if it was dropped from the Empire State Building.
Dropped from: Golden Gate Bridge
Time (seconds): t = √(2h/g)
To calculate the time, we need to know the height of the Golden Gate Bridge. The height of the Golden Gate Bridge's main towers is approximately 227 meters. Plugging in the values into the formula:
t = √(2 * 227 / 9.8) ≈ √(46.34) ≈ 6.81 seconds
So, it would take approximately 6.81 seconds for a ball to hit the ground if it was dropped from the Golden Gate Bridge.
Dropped from: Statue of Liberty
Time (seconds): t = √(2h/g)
To calculate the time, we need to know the height of the Statue of Liberty. The height of the Statue of Liberty from the ground to the tip of the torch is approximately 93 meters. Plugging in the values into the formula:
t = √(2 * 93 / 9.8) ≈ √(18.88) ≈ 4.35 seconds
So, it would take approximately 4.35 seconds for a ball to hit the ground if it was dropped from the Statue of Liberty.
Finally, if the ball is dropped from the top of a table, which is a much lower height, the time it takes to hit the ground is negligible. It would take a fraction of a second for the ball to reach the ground.
Remember, these calculations assume no air resistance and that the ball is dropped without any initial velocity.
