Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.
Use the vocabulary words from"Read It"to complete the
following sentences. (rock cycle)
Answers
The rock cycle demonstrates how rocks repeatedly transform from one type to another due to a variety of natural processes. When rock is eroded into small pieces, these smaller pieces are compacted to become a sedimentary rock. That rock can then melt to become magma, then cooled and solidified into an igneous rock. If intense heat and pressure is applied to this rock, it will become a metamorphic rock. Then the whole process can occur again, sometimes in a completely different order.

Answer: Free nitrogen comes from bacteria breaking down the nitrogen compounds which causes it to be released in the air. Fix nitrogen is from soil, plants and animals consuming it which causes it to recycle, nitrogen is cycled through: plants, soil, animals, bacteria and water and the atmosphere. I hope this helped!
Explanation:
Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

Camilo and his parents travel to Yellowstone National Park for a vacation. They read that below Yellowstone National Park lies a supervolcano that is responsible for small earthquakes and hotspot activity in the area.
The convection of hot rock transfers heat throughout Yellowstone National Park. This heat transfer causes geysers and hot springs to form. Explain the process of convection that rock in the mantle of Earth undergoes.
Answers
Answer:
The Earth is hotter at the center and cooler at the surface. Convection occurs when cooler, denser magma near the surface sinks back toward the core. Warmer, less dense magma near the core is displaced upward toward the surface.
At Yellowstone, there is a hotspot where the crust is thinner and the magma comes closer to the surface.

By adding tape to his BAAD, Cramwood increased its mass and increased
its inertia. The bigger BAAD requires more force to stop and ends up smacking Cramwood in the head when he applies the brakes.
What is inertia?Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.
The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.

Pair 1
Explanation:
The poles are opposite, so opposite closer together and the distance is closer together, so there is stronger magnetic field
The pair of magnet that have the greatest magnitude would be Pair 1.
Why do they have the greatest magnitude ?Magnets will only attract each other and therefore have a great magnitude if they are facing opposite poles. Pair 3 are therefore out because it has the same pole facing the other.
Magnitude of magnetic force will increase the closer the magnets are to each other. Seeing as Pair 1 has the lowest distance of 0. 3 cm, it means that Pair 1 would have the greatest magnitude.

In the same science fair, Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscope, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
List three controlled variables in this experiment.
Answers
Answer:
Independent variable- effect of caffeine
Dependent variable- heart rate
Hypothesis- If a stimulant such as caffeine is administered to earthworm, then its heart rate increases. The experiment is based on the research question; "Does caffeine increase the heart rate of an earthworm?" We can see from this research question that the independent variable is the effect of caffeine and the response it produces is a change in the heart rate (the dependent variable)
This now leads us to a hypothesis that states thus; 'If a stimulant such as caffeine is administered to earthworm, then its heart rate increases.'
Controlled variables are:- amount of caffeine she adds
- earth worm (in natural state)
- how much caffeine is actually absorbed by the worm

Name the process in the mantle that causes the plates to move and explain how the process occurs/happens/works.
Answers
Mantle convection
Explanation:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
Answer: The Convection Cell
Explanation: Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
Answers
The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.
Buried rocks melt deep within the mantle.
